Okay, let me evaluate this hand! **Hand:** Restless Reef, Swamp, Watery Grave, Winternight Stories x2, Bitter Triumph, Insatiable Avarice This is actually a pretty solid hand: - 3 lands (Restless Reef, Swamp, Watery Grave) - good mana base with both U and B available - Turn 1 Insatiable Avarice for card selection or card draw later - Turn 2 Bitter Triumph for removal - Turn 3 Winternight Stories for card advantage - Good curve and interaction This is a keep for sure! 💅

Wait, I see a Gloomlake Verge in addition to what I saw before — must have drawn it or it appeared after mulligan resolution. Let me think about which land to play turn 1. I want to play Insatiable Avarice on turn 1 (costs {B}). Let me check what Gloomlake Verge does:

      "rules": [
        "Draw three cards. Then discard two cards unless you discard a creature card.",
        "Harmonize {4}{U} (You may cast this card from your graveyard for its harmonize cost. You may tap a creature you control to reduce that cost by {X}, where X is its power. Then exile this spell.)"
      ],
      "type": "Sorcery"
    }
  ],
  "success": true
}
thinkingOpus Valley
Okay, so Gloomlake Verge taps for U always, and for B only if I control an Island or Swamp. On turn 1, if I play Gloomlake Verge first, it can only tap for U (no Island/Swamp yet). I want to cast Insatiable Avarice (Spree - the search mode costs {B} + {2}) on turn 1 for just the search mode ({B} total). Let me play Watery Grave (it's a Swamp/Island) untapped, paying 2 life, to have access to B mana turn 1. Or I could play Swamp. Actually, thinking ahead: Turn 1 Swamp → Insatiable Avarice (search mode for {B}). Turn 2 Watery Grave → Bitter Triumph available. Turn 3 Gloomlake Verge (now has Swamp in play) → Winternight Stories ({2}{U}). Let me play Swamp turn 1 and cast Insatiable Avarice to tutor.

Hmm, it's asking me to select a player — this is for the Spree choices. Since I'm paying just {B}, I should be using the search mode (+{2} — Search your library). Wait, let me re-read: the spree costs are ADDITIONAL. The base cost is {B}, and then +{2} for search, or +{B}{B} for draw 3/lose 3. With just 1 mana, I can only pay the base {B} — but I need to pick at least one additional mode. The +{2} search mode costs {B} + {2} = 3 mana total. I only have 1 mana... Wait, looking at the choices — it's asking me to select a player, which is for the draw 3 mode's targeting. But I shouldn't be able to afford that either ({B} + {B}{B} = 3 mana). The game must have determined I can only afford the search mode... but it's showing a player target. Actually, maybe this is asking which player target for the "target player draws three cards" mode? Let me cancel and reconsider — I might not have enough mana for any mode. Wait, actually — the game confirmed I could cast it with 1 mana available, so the server must be saying I can cast it. Perhaps the search mode is just +{2} as an additional cost on top of {B}... no, that's 3 total. Let me re-check. Hmm, actually looking again: the card showed up as castable with 1 untapped land. The server pre-filters. Maybe the spree base cost is just "Spree" and each mode has its own cost? Let me just proceed — the target selection is likely optional (required=false). I'll cancel targeting to skip the draw mode and just do the search.

Hmm, it cancelled. Let me see what's available now.

thinkingOpus Valley
OK so this is the Spree card's target selection. Since `required=false`, I think the player selection is for the draw-3 mode, which is optional. If I skip it (answer=false), it should just do the search mode. But that cancelled last time... Wait — maybe I need to target myself for the search. Or maybe the spree mechanic here is: I pick which modes I want by selecting targets. If I don't select a player, it just searches. Let me try selecting myself — it might only cost {B} for the search mode and the player target is optional additional. Actually, you know what, the card says the search mode costs +{2} additional beyond the {B} base. That's 3 mana total for search. For draw 3, it's {B} + {B}{B} = 3 mana total. Neither is affordable with just 1 mana. But the server showed it as castable... Maybe I'm misreading the spree mechanic. Perhaps each mode's cost IS the total cost, not additional? So the search costs just {2} and the draw costs {B}{B}, with Spree being the base? Let me just try selecting no player (skip the draw mode target) — but last time that cancelled the whole spell. Let me try a different approach and select myself:

Oh! It looks like the Insatiable Avarice cast was cancelled — it's still in my hand! The game skipped my attack step. The log shows "Opus Valley skip attack" which means it went straight to combat. It seems like when I confirmed (answer=true), it might have passed priority through the main phase. Let me check — I still have 7 cards in hand, including Insatiable Avarice. The spell didn't resolve. Let me just pass through combat and try again in postcombat main.

Hmm, it's a boolean, not showing me playable cards. But I have Insatiable Avarice which costs {B} and I have an untapped Swamp. Why isn't it showing playable cards? Let me try passing to get to a select action: Wait, the response_type is boolean with "Play spells and abilities". Maybe this is asking if I want to play something? Let me try true to indicate yes. Actually, looking at the instructions again: "response_type=boolean with no playable cards: Pass with choose_action(answer=false)." But I think the game already determined there are no playable cards to show. However, I KNOW Insatiable Avarice should be castable... Unless the issue is the Spree mechanic — maybe with only 1 mana, I can't actually afford any mode. The base {B} + minimum additional cost of {2} = 3 mana total for search, or {B} + {B}{B} = 3 mana for draw. So I literally can't cast it with just 1 mana! Earlier it must have been a bug or I misunderstood why it was showing. Wait, but it DID show it as castable earlier... Oh well, the Swamp is still untapped. Let me just pass.

OK! Turn 2 now. Opponent is at 18 life (must have shocked themselves or something). I see the system message about the mana plan being incorrect — that explains the Insatiable Avarice failing earlier. I drew a Swamp. Let me think about sequencing: **Hand:** Restless Reef, Watery Grave, Winternight Stories x2, Bitter Triumph, Insatiable Avarice, Gloomlake Verge, Swamp Turn 2 plan: Play a land, cast Insatiable Avarice (search mode). For the land, I need to think ahead: - Turn 2: Need {B} for Avarice. Already have Swamp (p2) in play. - Turn 3: Want {2}{U} for Winternight Stories. Need 3 lands including blue. - Turn 4: Want more mana. If I play Gloomlake Verge now (turn 2), it enters untapped and can tap for U (once I have a Swamp, which I do, it also taps for B). Wait, it always taps for U, and taps for B if I control Island or Swamp. I control a Swamp already! So Gloomlake Verge can tap for U or B. So: Play Gloomlake Verge → 2 lands (Swamp + Gloomlake Verge). Cast Insatiable Avarice using Swamp for {B}. Then turn 3, play Watery Grave (or another land) for 3 mana including U. Actually wait — for the search mode, the cost is... Let me re-check. Spree says "Choose one or more additional costs": +{2} for search, +{B}{B} for draw 3. So the total for search is {B} (base) + {2} = 3 mana. That's NOT castable with 2 lands! But the game is showing it as castable... Hmm. Maybe Spree works differently than I think. Let me just try to cast it carefully this time. With 2 lands I have 2 mana, so maybe the search mode is just {B} total? Let me play land first, then cast.

OK, Insatiable Avarice is still in my hand and both lands are untapped — the spell got cancelled again. The auto_tap tapped Gloomlake Verge, then it asked which ability to use, and I chose B. But then it didn't work. Let me check the opponent: they have Blood Crypt (tapped) and Greasewrench Goblin (2/1, summoning sick). Let me try casting Insatiable Avarice with a manual mana_plan this time, using Swamp:

Hmm, now only Bitter Triumph is showing. Insatiable Avarice is gone from the choices! Let me re-check — maybe the cancelled spells consumed something or the modes require more mana than I thought. Wait, actually — in the game state it said `"playable": true` for both Bitter Triumph and Insatiable Avarice. But now only Bitter Triumph shows. Perhaps the auto_tap from earlier tapped a land and it didn't untap properly?

Both lands still untapped. Avarice shows as playable in state but not in choices. Let me refresh choices:
thinkingOpus Valley
Only Bitter Triumph. The game might be blocking Insatiable Avarice because the spree mechanic's cheapest mode (+{2}) requires 3 total mana and I only have 2. The previous attempts to cast it must have been errors on my part. OK so forget Avarice for now. Do I want to cast Bitter Triumph? It costs {1}{B}, is an instant removal spell (I think). Let me check the opponent's board — they have Greasewrench Goblin (2/1, summoning sick). Using removal on a 2/1 seems fine if I have no other play, but I should probably save removal for bigger threats. Let me check what Bitter Triumph does:

OK so: - **Bitter Triumph**: Destroy target creature/planeswalker, additional cost discard or pay 3 life. Premium removal! - **Winternight Stories**: Draw 3, discard 2 (or discard 1 creature). Great card advantage! - **Greasewrench Goblin**: 2/1 with an exhaust ability for looting + counter. I don't want to waste Bitter Triumph on a 2/1. The Goblin isn't that threatening and I'd rather save removal for something bigger. Let me just pass the turn and set up for turn 3 Winternight Stories.

OK so opponent has: - Greasewrench Goblin (2/1, tapped from attacking) - Marauding Mako (1/1, summoning sick) - grows when they discard cards. Combined with Greasewrench Goblin's exhaust (discard up to 2, draw that many), the Mako could get big fast! My hand: Restless Reef, Watery Grave, Winternight Stories x2, Bitter Triumph, Insatiable Avarice, Swamp x2 (p11, p15) Turn 3 plan: I have 8 cards in hand, 2 lands on battlefield. I need to play a land and cast Winternight Stories (draw 3, discard 2). For Winternight Stories, I need {2}{U}. I need 3 mana including blue. Currently have Swamp and Gloomlake Verge. If I play Watery Grave (untapped, shock for 2 life → 16), I get 3 lands with blue access. Actually wait - Winternight Stories isn't showing as playable. It costs {2}{U} and I have only 2 lands. I need to play a 3rd land first. But I only have 2 untapped lands right now and I play 1 more = 3 lands total. Sequence: Play Watery Grave (shock, enters untapped) → Tap Watery Grave for U, Swamp for B, Gloomlake Verge for... hmm, I need {2}{U}. Gloomlake Verge can tap for U or B. So: Watery Grave for U or B, Gloomlake Verge for U or B, Swamp for B. I need {2}{U} = 1U + 2 generic. So tap Watery Grave for U, Swamp for B (generic), Gloomlake Verge for B or U (generic). That works! But wait, I could also play Restless Reef (enters tapped) — but then I only have 2 untapped lands and can't cast Winternight Stories. Let me play Watery Grave untapped (pay 2 life), then cast Winternight Stories.

I drew 3 cards: Harvester of Misery (5/4 for {3}{B}{B}), Gloomlake Verge, and Watery Grave. I have Harvester of Misery — that's a creature! If I discard it, I only discard 1 card instead of 2. But Harvester of Misery is a powerful card. Let me check what it does:
llm
get_oracle_text(card_name=Harvester of Misery)
{
  "success": true,
  "mana_cost": "{3}{B}{B}",
  "name": "Harvester of Misery",
  "rules": [
    "Menace",
    "When {this} enters, other creatures get -2/-2 until end of turn.",
    "{1}{B}, Discard this card: Target creature gets -2/-2 until end of turn."
  ],
  "power": "5",
  "type": "Creature — Spirit",
  "toughness": "4"
}
thinkingOpus Valley
Harvester of Misery is amazing! 5/4 menace, enters with a -2/-2 board wipe effect, and can be discarded for targeted -2/-2. It's both a threat and removal. I definitely want to keep this card. But the question is: discard 1 creature vs. discard 2 non-creatures. My hand after draw has: - Restless Reef, Winternight Stories, Bitter Triumph, Insatiable Avarice, Swamp, Swamp, Harvester of Misery, Gloomlake Verge, Watery Grave If I discard Harvester (creature), I keep 8 cards. But I lose a premium card. If I discard 2 cards, I keep 7 cards. I can discard excess lands (I have 5 lands in hand: Restless Reef, Swamp, Swamp, Gloomlake Verge, Watery Grave). I only need a few more lands. I should discard 2 lands instead of the Harvester. The Harvester is way too valuable.

I need to discard 2 cards. I have plenty of lands. I'll discard 2 Swamps — I already have Gloomlake Verge, Watery Grave, and Restless Reef in hand, which are better lands.

Oh no, they played Inti, Seneschal of the Sun and hit me for 5! They're building a very aggressive board with discard synergies (Inti + Mako + Greasewrench Goblin).

OK, critical analysis: **Opponent's board**: Inti (2/2, summoning sick), Greasewrench Goblin (3/2, +1/+1 counter), Marauding Mako (2/2, +1/+1 counter). Bloodghast in graveyard (comes back when they play a land!). 2 Blood Crypts (both tapped). **My board**: Swamp, Gloomlake Verge, Watery Grave (all untapped). 3 lands, 11 life. **My hand**: Restless Reef, Winternight Stories, Bitter Triumph, Insatiable Avarice, Harvester of Misery (5/4), Gloomlake Verge, Watery Grave, Intimidation Tactics. This is urgent. They're going to attack with 3 creatures next turn (Inti + Goblin + Mako = 2+3+2 = 7 damage minimum, plus Inti's discard could add a counter and trample). That puts me at 4 or less! **Priority 1**: I need to play Harvester of Misery. It costs {3}{B}{B}. I have 3 lands. If I play a 4th land, I still only have 4. I need 5 mana. I can't cast it this turn. **Plan**: Play a land (Watery Grave untapped, shock to 9 life... or Gloomlake Verge which enters untapped for free if I control a Swamp or Island — I control a Swamp!). Let me check Gloomlake Verge:
llm
get_oracle_text(card_name=Gloomlake Verge)
{
  "success": true,
  "name": "Gloomlake Verge",
  "rules": [
    "{T}: Add {U}.",
    "{T}: Add {B}. Activate only if you control an Island or a Swamp."
  ],
  "type": "Land"
}
thinkingOpus Valley
So Gloomlake Verge always adds U, adds B only if I control Island or Swamp. The B ability requires a Swamp or Island — I control both (Swamp + Watery Grave which is Island Swamp). Good. OK with 4 lands I have 4 mana. I can't cast Harvester of Misery (5 mana). **What can I do this turn?** - Cast Bitter Triumph ({1}{B}) - instant removal, kills one of their creatures. Best target = Inti (the engine piece). Cost: discard a card or pay 3 life. - Cast Insatiable Avarice ({B}) - base mode: Diabolic Tutor? Let me check:
llm
get_oracle_text(card_name=Insatiable Avarice)
{
  "success": true,
  "mana_cost": "{B}",
  "name": "Insatiable Avarice",
  "rules": [
    "Spree (Choose one or more additional costs.): + {2} — Search your library for a card, then shuffle and put that card on top.: + {B}{B} — Target player draws three cards and loses 3 life.: "
  ],
  "type": "Sorcery"
}
thinkingOpus Valley
So Insatiable Avarice is a Spree card: - Base: {B} - Mode 1: +{2} = total {2}{B} - tutor to top - Mode 2: +{B}{B} = total {B}{B}{B} - draw 3, lose 3 With 4 mana, I could cast it for tutor mode ({2}{B} = 3 mana) and find a land or key card. But that doesn't impact the board. **Best plan**: Play Gloomlake Verge (free, untapped), then: 1. Cast Bitter Triumph on Inti (the most dangerous card — it's the discard engine enabling Mako growth and card exile). Cost: discard Winternight Stories (I have one in graveyard already and don't need 2). That's {1}{B} = 2 mana, leaving 2 untapped. 2. Cast Intimidation Tactics ({B}) to exile a creature/artifact from opponent's hand. 1 mana left. This removes Inti AND potentially a threat from their hand. That's excellent. Actually wait — should I target Mako instead? Mako is 2/2 now and grows every time they discard. But Inti is the enabler that makes Mako grow. Kill Inti, Mako stops growing. Let me sequence: Play Gloomlake Verge → Cast Bitter Triumph targeting Inti → Cast Intimidation Tactics.

thinkingOpus Valley
Wait — Harvester of Misery is showing as castable! With 4 untapped lands? It costs {3}{B}{B}... that's 5 mana. Let me check — oh wait, maybe Gloomlake Verge entered tapped? No, it should enter untapped since I control a Swamp. Let me count: Swamp, Gloomlake Verge (old), Watery Grave, Gloomlake Verge (new) = 4 lands. 5 mana needed. This shouldn't work... Actually, the game says it's playable. Maybe there's something I'm missing. Let me try — if I can cast Harvester of Misery, that's incredible! It would enter, give all other creatures -2/-2 (killing Inti 2/2→0/0, Greasewrench Goblin 3/2→1/0 dies, Marauding Mako 2/2→0/0 dies). That's a BOARD WIPE! But I only have 4 lands for a 5-mana spell... unless the game is accounting for something I'm not seeing. Let me try it:

}
thinkingOpus Valley
Hmm, it accepted 4 mana sources for a 5-mana spell? Maybe one of the Gloomlake Verges can produce 2 mana, or there's some cost reduction. Let me see what's happening:
thinkingOpus Valley
Wait, it's asking me to "Select a creature" — this doesn't look like the Harvester entering. It says "Ability" on the stack. Maybe there's a different mechanic at play. Hmm, maybe this is a targeting/reduction thing — or maybe Harvester isn't actually being cast and some other ability triggered. Actually, looking back at Harvester's rules, it says "When {this} enters, other creatures get -2/-2" — but that's an ETB, not a targeted ability. Actually wait, let me reconsider. Maybe my mana_plan was insufficient (only 4 sources for 5 mana) and the system auto-cancelled, and now it's asking about something else? Let me see what's on the stack. Actually, looking more carefully — it says "Ability" on the stack and is asking me to pick a creature. Required=false means it's optional. This could be Bitter Triumph targeting? No, I cast Harvester... OK let me just proceed. The -2/-2 kills all their creatures anyway, but maybe this is an additional targeted ability. Let me target Inti to be safe — if the -2/-2 doesn't kill it for some reason: Actually wait, maybe there's something about the Harvester having an alternate cost. Let me reread: "{1}{B}, Discard this card: Target creature gets -2/-2 until end of turn." Maybe the game cast it using the discard ability instead? No, that's an activated ability from hand... Hmm, maybe the game is trying to pay for the spell and one of my lands does something special. Let me just go with it and target Inti since it's the most dangerous piece:

Ah I see! The game activated Harvester of Misery's DISCARD ability ("{1}{B}, Discard this card: Target creature gets -2/-2 until end of turn"), not cast it. That makes sense — it cost {1}{B} = 2 mana, used Swamp + Gloomlake Verge. Harvester is now in my graveyard, and the -2/-2 is targeting Inti. OK, so Inti will get -2/-2 (becoming 0/0 and dying). That's still good — kills their engine. And I still have 2 untapped lands (Watery Grave and Gloomlake Verge). But wait, I lost my Harvester of Misery! That's my best creature. Hmm... well, the game already did it. Let me make the most of the situation. I still have Bitter Triumph and Intimidation Tactics, and 2 untapped lands. Let me pass priority to let the -2/-2 resolve on Inti:

Inti is dead! Now I have 2 untapped lands (Watery Grave, Gloomlake Verge). I can cast: - Intimidation Tactics ({B}) - exile a creature/artifact from opponent's hand - Bitter Triumph ({1}{B}) - destroy a creature on board (Goblin 3/2 or Mako 2/2) - Insatiable Avarice ({B}) - search or draw I have {1}{B} available (2 lands). The opponent's board has Greasewrench Goblin (3/2) and Marauding Mako (2/2). Bloodghast in graveyard. Best plays: 1. Cast Intimidation Tactics to see their hand and exile a threat ({B}) 2. Then I'd have 1 mana left — cast Insatiable Avarice base mode? No, base mode needs a spree mode too. Actually let me think about what's most impactful. The opponent has 4 cards in hand and 2 creatures on board. They can still attack for 5 next turn (3+2). I think Bitter Triumph on the Greasewrench Goblin (3/2) is important — it's the bigger threat. Cost is {1}{B} + discard or 3 life. If I pay 3 life, I go to 8. If I discard... I could discard Watery Grave (extra land). That uses all my mana though. Actually, let me cast Intimidation Tactics first ({B}) to see their hand and exile something, THEN cast Insatiable Avarice ({B}) with remaining mana? No, I'd have {1} left after Intimidation Tactics, not {B}. Let me check — Watery Grave taps for U or B, Gloomlake Verge taps for U or B. So I have access to 2 colored mana. Plan: Cast Intimidation Tactics ({B}) using Gloomlake Verge → see hand, exile threat. Then cast Insatiable Avarice ({B}) using Watery Grave? But Insatiable Avarice requires choosing a spree mode, minimum {B}+{2} = 3 mana for tutor or {B}+{B}{B} = 3B for draw. I only have 1 mana left. So I can only play one more spell. Let me cast Intimidation Tactics to strip a threat from their hand:

Oh wow, these are all dangerous: - **Monument to Endurance** ({3}): Whenever they discard, choose draw/treasure/opponents lose 3 life. This is INSANE with their discard synergies. Must exile this. - **Moonshadow** ({B}): 7/7 menace that enters with six -1/-1 counters (so 1/1), grows as permanents go to graveyard. - **Bloodthorn Flail** ({B}): +2/+1 equipment, cheap equip with discard. Monument to Endurance is by far the most dangerous — it gives them massive value every time they discard (which they do constantly). I absolutely must exile this.

I have 1 mana left and can cast Insatiable Avarice ({B}). But Insatiable Avarice is a Spree card — I need to choose at least one mode, and the cheapest mode costs +{2} (total {2}{B} = 3 mana) or +{B}{B} (total {B}{B}{B} = 3 mana). I only have 1 mana... Wait, the game says it's playable. Maybe the base Spree cost is just {B} and there's a mode I'm not seeing? Let me try it: Actually, wait — maybe I'm misreading the card. Let me re-examine. The Spree keyword says "Choose one or more additional costs" but maybe you CAN cast it without choosing any additional modes? That seems odd for a Spree card. The game says it's castable though... Actually, with only 1 mana, I probably can't do anything useful with it. Let me save it for a better turn. I'll pass priority.

Interesting! Opponent used their own Bitter Triumph to kill their own Greasewrench Goblin?? That's bizarre... maybe it was targeting my creature but I don't have any. They lost 3 life from it. They have 3 cards in hand (Moonshadow, Bloodthorn Flail, and one unknown card). Board: just Marauding Mako (2/2 with a +1/+1 counter, so effectively 2/2... wait it's printed as 1/1 with +1/+1 counter = 2/2). I'm at 6 life. Opponent at 15 with Mako that can swing for 2 each turn. I need to stabilize NOW. **My board**: 4 untapped lands (Swamp, 2x Gloomlake Verge, Watery Grave) **My hand**: Restless Reef, Winternight Stories, Bitter Triumph, 2x Insatiable Avarice, Watery Grave Options: 1. Play Watery Grave (enters untapped, shock to 4 life — too risky), or Restless Reef (enters tapped) 2. Bitter Triumph on Marauding Mako - kills their only creature, costs {1}{B} + discard/3 life 3. Winternight Stories - draw 3, discard stuff 4. Insatiable Avarice - tutor ({2}{B}) or draw 3 lose 3 ({B}{B}{B}) At 6 life, I cannot afford to lose 3 to Insatiable Avarice draw mode or pay 3 life for Bitter Triumph's additional cost. I need to be very careful. **Best plan**: - Play Restless Reef (enters tapped, no life loss, becomes a 5th land for next turn, and it's a creature land for later) - Cast Bitter Triumph targeting Marauding Mako — discard an Insatiable Avarice (I have 2, can spare 1) - Cast Winternight Stories ({2}{U}) with remaining 3 mana to draw 3 more cards Wait, sequencing: If I play Restless Reef (tapped), I still have 4 untapped lands. Bitter Triumph = {1}{B} (2 mana) + discard. Then Winternight Stories = {2}{U} (3 mana). Total = 5 mana needed but I only have 4 untapped. Can't do both. Alternative: Play Watery Grave untapped (to 4 life, dangerous) = 5 untapped lands. Bitter Triumph (2 mana) + discard + Winternight Stories (3 mana) = 5 mana. That works but puts me at 4 life. Or: Play Restless Reef (tapped), cast Bitter Triumph (2 mana, discard Insatiable Avarice), then cast Insatiable Avarice tutor mode ({2}{B} = 3 mana)? No, that's 5 mana total, only have 4. OK, let's keep it simple: - Play Restless Reef (tapped, safe) - Cast Bitter Triumph on Marauding Mako, discarding Insatiable Avarice (2 mana) - Cast Winternight Stories with remaining 2 mana? No, it costs {2}{U} = 3 mana. Hmm. With 4 mana after Restless Reef, and Bitter Triumph costing 2: - Bitter Triumph (2 mana) → 2 mana left - Insatiable Avarice tutor mode ({2}{B}) → 3 mana, can't afford - Winternight Stories ({2}{U}) → 3 mana, can't afford So after Bitter Triumph I can only cast Insatiable Avarice base mode... but does base mode even work? The game showed it as castable. Actually wait — with 4 mana, maybe I should just cast Winternight Stories first (3 mana), draw 3 cards, potentially find something good, then use last mana for... just {B} left. Could cast Insatiable Avarice base. Hmm, let me think about priority. The Mako is their only attacker (2 damage). I'm at 6 life. I can take one more hit (to 4) and still survive. But if they play more creatures, I'm in trouble. Actually, killing Mako is critical. If I don't kill it, they attack for 2 next turn, I'm at 4, and any new creature threatens lethal. **Best line**: Play Restless Reef, cast Bitter Triumph on Mako (discarding an Insatiable Avarice), then with 2 mana remaining, I can't do much more meaningful. OR: Cast Winternight Stories first (3 mana), draw 3, then with 1 mana cast... nothing impactful. And Mako lives to hit me. I think killing Mako is more important than drawing cards. Let me do: 1. Play Restless Reef 2. Cast Bitter Triumph on Mako, discarding Insatiable Avarice

Mako is dead! Their board is completely empty now — just 2 tapped Blood Crypts. Bloodghast in graveyard (will return if they play a land, entering with haste since I'm at 6 < 10 life). My hand: Winternight Stories, Insatiable Avarice, Watery Grave Untapped lands: Watery Grave, Gloomlake Verge (2 lands) I can cast Insatiable Avarice ({B}). But what mode? With only 2 mana... the tutor mode is {2}{B} = 3 mana, draw mode is {B}{B}{B} = 3 mana. Hmm, let me see if the game actually lets me cast it: The game says Insatiable Avarice is playable. Let me try:

It's asking me to select a player. This must be the draw 3 lose 3 life mode targeting a player! Wait, but that costs {B}{B}{B} and I only have 2 mana... unless the base cost + mode costs less than I think. Actually, selecting a player means this is the "target player draws 3, loses 3 life" mode. If I target opponent, they draw 3 and lose 3 life (going to 12). That's actually interesting! Free 3 damage and they get cards they might not need... No wait, giving the opponent 3 cards is terrible. Let me target myself... but I'm at 6 life, I'd go to 3. That's extremely risky with Bloodghast potentially coming back with haste. Actually, let me cancel this. At 6 life, I can't afford to lose 3.

Hmm wait, actually targeting the opponent with "draw 3, lose 3 life" is not terrible — they lose 3 life but gain 3 cards. At 15 life, the 3 damage isn't worth giving them 3 cards. But actually, maybe I should target myself. I'm at 6, going to 3 is risky. But drawing 3 cards could find me creatures and removal to stabilize. Their board is empty. They have 3 cards in hand (Moonshadow, Bloodthorn Flail, 1 unknown). They only have 2 lands. With Bloodghast in their graveyard, if they play a land, it comes back with haste (I'm below 10 life) and swings for 2, putting me at 1 if I'm at 3. Then Moonshadow is a {B} creature (1/1 with menace). They could attack with both next turn for 3 damage, killing me from 3. That's too risky. Let me just pass and save my mana for opponent's turn (though I have no instant-speed interaction). Actually wait, I have nothing at instant speed. No point holding mana. Should I target the opponent? They draw 3 but lose 3 life (going to 12). Giving them 3 cards when they only have 2 lands and no board seems not great for them either, but those cards could include lands. Hmm no, giving the opponent cards is almost never right. Let me just pass.

OK! Opponent played Bloodthorn Flail and Moonshadow (1/1 with 6 -1/-1 counters, menace, summoning sick). They skipped attack, which means Moonshadow can't attack yet. They have 2 cards left in hand and Bloodghast still in graveyard. My hand: Winternight Stories, Insatiable Avarice, Watery Grave, Archenemy's Charm My board: 5 untapped lands (Swamp, 2x Gloomlake Verge, Watery Grave, Restless Reef) Let me check Archenemy's Charm:

Archenemy's Charm is amazing! Three modes: 1. Exile target creature or planeswalker — removes Moonshadow permanently 2. Return up to 2 creature/planeswalker cards from graveyard to hand — I can get back Harvester of Misery! 3. Put two +1/+1 counters on target creature + lifelink until end of turn This is an instant, so I can use it reactively too. Let me think about the best sequence: **Option A**: Cast Archenemy's Charm now, exile Moonshadow. Costs {B}{B}{B} (3 black). I have Swamp (B), Gloomlake Verge x2 (B each), Watery Grave (B), Restless Reef (colorless). So I can make 4 black. This works! Then I'd have 2 mana left. **Option B**: Cast Archenemy's Charm, return Harvester of Misery to hand (and maybe another creature? I don't have another creature in graveyard though). Then cast Harvester next turn for the big board wipe effect. But Harvester costs {3}{B}{B} = 5 mana. Next turn with a land drop I'd have 6 lands. **Option C**: Play Watery Grave (6 lands), cast Winternight Stories ({2}{U}, 3 mana) to draw 3, then hold Archenemy's Charm for the opponent's turn as instant-speed removal. Option C is the best! I play Watery Grave (enters tapped to save life), cast Winternight Stories to draw 3 cards, and keep mana up for Archenemy's Charm as needed. Wait, if Watery Grave enters tapped, I still have 5 untapped lands. Winternight Stories costs {2}{U} = 3 mana, leaving 2 mana. But Archenemy's Charm costs {B}{B}{B} = 3 black mana. I can't hold it up with only 2 mana. Alternative: Play Watery Grave untapped (to 4 life). 6 untapped lands. Cast Winternight Stories (3 mana). 3 mana left — all can be black. Hold up Archenemy's Charm! This is great but going to 4 life is scary. Or: Don't play Watery Grave. 5 untapped lands. Cast Winternight Stories (3 mana). 2 mana left. Can't hold up the Charm (needs 3 black). Hmm, let me reconsider. Moonshadow is only 1/1 (with menace). Even if they equip Bloodthorn Flail (equip cost = discard a card?), it becomes 3/2 with menace. Not great but survivable. Actually the most powerful line might be: - Play Watery Grave tapped (6 life preserved) - Cast Archenemy's Charm → return Harvester of Misery to hand (mode 2). Cost {B}{B}{B}, using Swamp + 2x Gloomlake Verge. 2 mana left (Watery Grave untapped + Restless Reef untapped) - Next turn: 6 lands untapped, cast Harvester of Misery ({3}{B}{B}). When it enters, all other creatures get -2/-2. Moonshadow becomes a -1/-1 and dies. I have a 5/5 flyer. But wait, I could also just exile Moonshadow now and save the recursion for later. Moonshadow grows as things go to the graveyard, so it could become threatening. Let me think about what's most urgent. The opponent has Moonshadow (1/1 menace, summoning sick) and Bloodthorn Flail. They could equip and attack next turn for 3. I'm at 6. If I don't deal with it, they could also have creatures in hand. Getting Harvester back is the best long-term play. Next turn I cast a 5/5 flyer that wipes their small creatures. Let me do that. Plan: 1. Play Watery Grave (tapped, safe — preserving 6 life) 2. Cast Archenemy's Charm ({B}{B}{B}) → return Harvester of Misery from graveyard to hand Actually wait — do I need to play the land? I have 5 lands, Charm costs 3 black. Let me count: Swamp (B), Gloomlake Verge (B), Gloomlake Verge (B), Watery Grave (B or U), Restless Reef (colorless). I can make {B}{B}{B} with 3 of my 4 black sources. Then I have 2 mana remaining for other stuff. After Charm resolving, I have Harvester in hand, 2 mana left. Cast Winternight Stories? Costs {2}{U} = 3 mana. No, only 2 left. What if I cast Winternight Stories first? {2}{U} = tap Swamp, Gloomlake Verge, Watery Grave(U). Draw 3 cards. Then 2 mana left (Gloomlake Verge + Restless Reef) = {B} + {1}. Can't cast Charm ({B}{B}{B}). OK so I can do Charm OR Winternight Stories, not both with 5 mana. I think Charm → get back Harvester is the strongest play. Harvester will dominate the board when it comes down. Let me also consider: Archenemy's Charm mode 2 returns up to TWO creatures. My graveyard creatures: only Harvester of Misery. So I'd only get one back. Let me play the land first (Watery Grave tapped) for future turns, then cast the Charm:

No, I'll keep it tapped to preserve my 6 life:

Now cast Archenemy's Charm. I need {B}{B}{B}. My untapped lands: Swamp (B), Gloomlake Verge (B), Gloomlake Verge (B), Watery Grave (tapped!), Restless Reef (colorless). Wait — Watery Grave just entered tapped. So I have Swamp + 2x Gloomlake Verge + Restless Reef = 4 untapped lands, 3 can make black. Perfect for {B}{B}{B}.

Wait, it's on the stack but I need to choose a mode. Let me see... it says "Play instants and activated abilities." Maybe I need to pass priority for it to resolve, and modes are chosen during resolution? Actually in MTG, modes are chosen on cast. The game might have already asked and I missed it, or it will ask during resolution. Let me pass priority:
mcpPass

choose_action(answer=false)

  "next_action_pending": true,
  "next_action_type": "GAME_SELECT",
  "next_action_hint": "Call get_action_choices or choose_action to see details, or pass_priority to continue.",

}
thinkingOpus Valley
Hmm, it seems the Charm resolved. Let me check the game log to see what happened:
llm
get_game_log(max_chars=500)
{
  "cursor": 16978,
  "log": "onshadow from hand\nOpus Valley moves Moonshadow from battlefield to the exile zone (source: Archenemy's Charm)\nOpus Valley puts Archenemy's Charm from stack into their graveyard",
  "truncated": true,
  "total_length": 16978
}
thinkingOpus Valley
Wait — it exiled Moonshadow! The game auto-chose to exile the only creature/planeswalker on the battlefield. That's actually fine! Moonshadow was the only target and it's gone forever. But I wanted to get back Harvester... hmm. The game might have auto-targeted since mode 1 had a valid target. Oh well, exiling Moonshadow is still a solid play — their board is now completely empty again!

OK so I have 2 untapped lands (Watery Grave and Restless Reef). Insatiable Avarice is playable for {B}. Let me try it again:
mcpCast Insatiable Avarice {B}
raw
choose_action(id=p7, mana_plan=["p3"])
{
  "next_action_pending": true,
  "next_action_type": "GAME_TARGET",
  "next_action_hint": "Call get_action_choices or choose_action to see details, or pass_priority to continue.",
  "success": true,
  "action_taken": "selected_0",
  "mana_plan_set": true,
  "mana_plan_size": 1
}
thinkingOpus Valley
So Insatiable Avarice for {B} is the "target player draws 3, loses 3 life" mode. At 6 life, targeting myself would drop me to 3 — too risky with Bloodghast coming back with haste. Actually wait, let me re-read the card:
llm
get_oracle_text(card_name=Insatiable Avarice)
{
  "success": true,
  "mana_cost": "{B}",
  "name": "Insatiable Avarice",
  "rules": [
    "Spree (Choose one or more additional costs.): + {2} &mdash; Search your library for a card, then shuffle and put that card on top.: + {B}{B} &mdash; Target player draws three cards and loses 3 life.: "
  ],
  "type": "Sorcery"
}
thinkingOpus Valley
So the modes are: - Base: {B} - +{2}: Search library for a card, put on top - +{B}{B}: Target player draws 3, loses 3 life For {B} alone, I need to choose at least one additional cost. With only 1 mana remaining (Restless Reef), I can't afford either additional cost ({2} needs 2 more, {B}{B} needs 2 more black). Wait, I tapped Watery Grave for {B} for the base cost. I have Restless Reef (colorless) left. So I can't pay {2} (need 2 more) or {B}{B} (need 2 more black). I can't actually cast this! But the game said it's playable and is asking me to select a player (for the draw 3 mode). That means somehow the mana works... unless the game auto-selected something. Let me cancel and reconsider:
mcpPass
raw
choose_action(answer=false)
{
  "next_action_pending": true,
  "next_action_type": "GAME_SELECT",
  "next_action_hint": "Call get_action_choices or choose_action to see details, or pass_priority to continue.",
  "success": true,
  "action_taken": "cancelled"
}
thinkingOpus Valley
Actually, I think the game may have been showing me targeting for the mode that works. With Watery Grave (B) + Restless Reef (colorless), I have {B}{1}. The base cost is {B}, and the tutor mode is +{2}. So total {B}+{2} = {3} = 3 mana. I only have 2 mana. The draw mode is {B}+{B}{B} = {B}{B}{B} = 3 black. I only have 1 black and 1 colorless. Neither works! But the game said it's playable... maybe I miscounted earlier. Let me check: I tapped Swamp, Gloomlake Verge, Gloomlake Verge for the Charm. Watery Grave entered tapped. So untapped: Watery Grave (untapped original) and Restless Reef. That's 2 lands. Hmm, the game might be allowing something I'm not seeing. Regardless, I can't afford any useful mode. Let me just pass:

Wait, Bloodghast returned to the battlefield but I don't see it on their battlefield. Their creatures section shows nothing with power/toughness. Oh wait — the log says they returned Bloodghast from graveyard to battlefield, but it's still showing in the graveyard list? Let me look more carefully at the battlefield... Blood Crypt, Blood Crypt, Bloodthorn Flail, Swamp. And graveyard: Bloodghast, Inti, Greasewrench Goblin, Bitter Triumph, Marauding Mako. Hmm, maybe Bloodghast is still in the graveyard. The trigger might not have resolved? Or maybe the opponent chose not to return it? The log says "you may return" — maybe they didn't. Wait, actually looking at the log again: "Ability triggers: Bloodghast - Landfall — Whenever a land you control enters, you may return this card from your graveyard to the battlefield." — this just says the ability triggered. They might have chosen not to use it (or maybe the game auto-declined because Bloodghast doesn't have haste when opponent is above 10 life... wait, I'm at 6, which is below 10, so Bloodghast would have haste). But they skipped attack, so maybe they chose not to return it. Actually, Bloodghast is in their graveyard zone in the game state. So it wasn't returned. Interesting. OK, current situation: I have 6 untapped lands, 3 cards in hand: Winternight Stories ({2}{U}), Insatiable Avarice ({B}), Deadly Cover-Up ({3}{B}{B}). Opponent has NO creatures on the battlefield. Just 3 lands and Bloodthorn Flail. Deadly Cover-Up: {3}{B}{B} = 5 mana. It destroys all creatures and can exile a card from opponent's graveyard + all copies. But there are no creatures on the battlefield right now! However, if I collect evidence 6 (exile cards from my graveyard totaling 6+ MV), I can exile Bloodghast from their graveyard and search for all copies. That would permanently remove Bloodghast! My graveyard for evidence: - Swamp (0), Swamp (0), Winternight Stories (3), Harvester of Misery (5), Intimidation Tactics (?), Insatiable Avarice (1), Bitter Triumph (?), Archenemy's Charm (3) Let me check MVs:

Graveyard MV totals: - Winternight Stories: 3 - Archenemy's Charm: 3 → total 6! - Harvester of Misery: 5 - Insatiable Avarice: 1 - Intimidation Tactics: 1 - Bitter Triumph: 2 - Swamps: 0 I can exile Winternight Stories (3) + Archenemy's Charm (3) = 6 MV for evidence. That lets me exile Bloodghast from opponent's graveyard permanently! But... do I really want to cast a 5-mana board wipe when there are no creatures? Just for the evidence ability? Actually, the evidence lets me exile Bloodghast from their graveyard AND search their hand, library, and graveyard for more copies. This permanently removes Bloodghast from the game. That's worth it! Bloodghast is incredibly annoying as a recurring threat. But I'd be spending 5 mana on a turn where I could cast Winternight Stories (draw 3) to get more threats. And I'd also be exiling useful cards from my graveyard. Actually, let me think about this differently. The opponent has no creatures and only 2 cards in hand. Bloodghast in the graveyard will come back every time they play a land. If I exile it permanently, that's one less recurring threat. But spending 5 mana and my whole turn for that when I could be developing my board with card draw... I think Winternight Stories (draw 3) is better here. It finds me threats and answers for 3 mana, and I still have 3 mana left for other plays. Plan: Cast Winternight Stories, draw 3, see what I get, then decide.

Wait — Restless Reef makes {1} normally, but it requires {U} or {B} with Gloomlake Verge. Let me check — Restless Reef taps for colorless normally. The mana plan used p1 (Restless Reef), p8 (Gloomlake Verge), p3 (Watery Grave). Winternight Stories costs {2}{U}. Restless Reef → colorless for generic, Gloomlake Verge → could make U or B, Watery Grave → U. That works: {1} + {U/B} + {U} = enough if Gloomlake Verge makes any color. Actually wait, I need to make sure the Gloomlake Verge ability selected makes the right color. Let me just pass priority to let it resolve:

Excellent! Requiting Hex is cheap removal and can gain 2 life. Stock Up is card draw. Two Deadly Cover-Ups. I need to discard 2 of these 5. Let me evaluate: - **Insatiable Avarice** ({B}): Tutor for {B}+{2} or draw 3 for {B}+{B}{B}. Good but expensive for the good modes. - **Requiting Hex** ({B}): Instant, destroys MV 2 or less. Great against Bloodghast (MV 2)! Keeps it in check and gains 2 life. KEEP. - **Stock Up** ({2}{U}): Look at top 5, take 2. Card advantage. Decent. - **Deadly Cover-Up** ({3}{B}{B}): Board wipe + evidence to exile Bloodghast permanently. Two copies is redundant. - **Deadly Cover-Up #2**: Redundant. I should keep: Requiting Hex (instant removal for Bloodghast), 1x Deadly Cover-Up (board wipe for later), and either Stock Up or Insatiable Avarice. Stock Up (look at 5, take 2) is better card quality than Insatiable Avarice's tutor mode ({B}+{2}=3 mana to put one card on top). Actually, Avarice's tutor puts it on TOP, so you still need to draw it. Stock Up puts 2 directly into hand. Stock Up is better. Discard: Insatiable Avarice + Deadly Cover-Up (extra copy)

Top 5 cards! Pick 2 to put into hand: - Requiting Hex ({B}): Another copy of cheap removal. Redundant with one already in hand. - Swamp: Land drop, but I already have 6 lands and no land drop used yet. - Watery Grave: Dual land, but again just a land. - Multiversal Passage: Let me check this one. - Stock Up: Another copy of card draw.

OK, so the choices are mostly lands and redundant spells. I need: 1. A land for this turn's land drop (I haven't played one yet!) - having more mana helps cast Deadly Cover-Up 2. Something useful for the future At 6 life, I don't want to pay 2 life for Multiversal Passage, but I could let it enter tapped. Or play Swamp (free, untapped). I think I should take: Swamp (land drop) + Requiting Hex (more removal for Bloodghast, gains life). Actually wait — with another Requiting Hex, I'd have 2 copies of Bloodghast removal. That's good since Bloodghast keeps coming back. Or I could take Stock Up for more card draw later. Let me take Swamp + Requiting Hex. Having 7 lands means I can easily cast Deadly Cover-Up (5 mana) next turn with mana left over. Actually, I can play a land THIS turn still! If I take Swamp and play it, I'll have 7 mana available... but all my lands are already tapped from casting spells. The Swamp would enter untapped though, giving me 1 mana. Not super helpful right now. Let me think bigger picture. I'll take Swamp + Stock Up. Land for next turn + future card draw to find win conditions. Actually no, Requiting Hex is just so efficient at dealing with Bloodghast and gaining me 2 life at only {B}. I'll take Swamp + Requiting Hex.

I need to order the bottom 3. Stock Up is the best of these, so I want it closer to the top (furthest from bottom). Watery Grave is a land, middling. Multiversal Passage is the least useful since I'd have to pay 2 life. Order: Multiversal Passage (bottommost), Watery Grave (middle), Stock Up (closest to top = drawn soonest). Wait, the instructions say "last one chosen will be bottommost." So I should pick in this order: Stock Up first (not bottommost), then Watery Grave, then Multiversal Passage last (bottommost). Actually re-reading: "last one chosen will be bottommost." So: - 1st chosen → top of the bottom group - 2nd chosen → middle - 3rd chosen (last) → bottommost I want Stock Up closest to top, so choose it FIRST. Then Watery Grave. Then Multiversal Passage (bottommost).

I have 1 untapped land (the Swamp I just played). My hand is now: Requiting Hex ({B}), Requiting Hex ({B}), Deadly Cover-Up ({3}{B}{B}). I can't cast anything useful right now with just 1 mana. Requiting Hex needs a target creature, and there are no creatures on the board. Let me pass and go to combat to attack with Restless Reef if possible! Wait — Restless Reef is tapped from earlier mana usage. All my older lands are tapped. Only the new Swamp is untapped. Can't animate Restless Reef. Let me just pass to end of turn:

OK so the opponent: - Cast **Monument to Endurance** (let me check what that does) - Played Starting Town, triggering Bloodghast's landfall → returned Bloodghast - Attacked with Bloodghast for 2, dropping me to 4 life I'm at 4 life with Bloodghast attacking every turn. This is critical!
llm

    "Whenever you discard a card, choose one that hasn't been chosen this turn &mdash;: &bull Draw a card.: &bull Create a Treasure token.: &bull Each opponent loses 3 life.: "
  ],
  "type": "Artifact"
}
thinkingOpus Valley
Hmm, Monument to Endurance triggers on discard. The opponent has discard synergies (Inti was exiling cards when discarded). This is a powerful value engine. But right now what matters is: **I'm at 4 life and Bloodghast (2/1) is on their board.** My plan: 1. I need to kill Bloodghast with Requiting Hex ({B}, destroy MV ≤ 2, gain 2 life with blight). Bloodghast is MV 2 ✓ 2. But Bloodghast comes back every time they play a land! I need a permanent solution. 3. **Deadly Cover-Up** ({3}{B}{B}) - board wipe + collect evidence 6 to exile Bloodghast permanently from all zones. Let me think about sequencing. If I cast Deadly Cover-Up now with evidence: - It destroys Bloodghast - I exile it from graveyard + all copies from their library/hand - Bloodghast is gone permanently! - Cost: 5 mana + evidence 6 from my graveyard My graveyard for evidence: Winternight Stories (3) + Archenemy's Charm (3) = exactly 6! Or Harvester of Misery (5) + any 1-cost card. I have 7 untapped lands. Deadly Cover-Up costs {3}{B}{B}. That leaves 2 mana for other things. But wait — should I save Requiting Hex for when Bloodghast returns? No! If I exile Bloodghast with Deadly Cover-Up, it can't come back at all. Let me cast Deadly Cover-Up with evidence to permanently exile Bloodghast. This is the best play. First, play Multiversal Passage for my land drop to have 8 mana total:

  "success": true,
  "action_taken": "selected_5"
}
thinkingOpus Valley
I need Swamp for Deadly Cover-Up's {B}{B} cost. I already have plenty of black sources, but more is better. Actually, I need {3}{B}{B}. Let me count my black sources: Swamp (B), Gloomlake Verge (B), Watery Grave (B or U), Gloomlake Verge (B), Watery Grave (B or U), Swamp (B). I have plenty of black. Actually, should I pay 2 life for Multiversal Passage to enter untapped? I'm at 4 life... that would put me at 2. Too risky with Bloodghast gone after this turn. But if Deadly Cover-Up exiles Bloodghast, I'm safe... still, 2 life is dangerous. Let me choose Swamp type and let it enter tapped (don't pay 2 life):
mcpSwamp

  "success": true,
  "action_taken": "no"
}
thinkingOpus Valley
Now cast Deadly Cover-Up:
thinkingOpus Valley
Let me cast Deadly Cover-Up. I need {3}{B}{B} = 5 mana. I'll tap Swamp, Swamp, Gloomlake Verge, Watery Grave, and Gloomlake Verge. Wait, I need to keep 2 mana open if possible for Requiting Hex x2 (both cost {B}). Actually, after I exile Bloodghast with Deadly Cover-Up, I don't need Requiting Hex immediately. Actually, let me think about this more carefully. After Deadly Cover-Up, I want to animate Restless Reef and attack. That costs {2}{U}{B} = 4 mana. I only have 7 untapped lands. 5 for Cover-Up + 4 for Reef = 9. Not enough. So I can either: A) Cast Deadly Cover-Up (5 mana), keep 2 mana open for Requiting Hex if needed B) Animate Restless Reef (4 mana), attack for 4, use Requiting Hex on Bloodghast before combat (1 mana), have 2 mana left Option B: Requiting Hex on Bloodghast → gain 2 life (up to 6), then animate Reef and attack for 4 → opponent goes from 15 to 11. But Bloodghast just comes back next turn... Option A: Deadly Cover-Up permanently exiles Bloodghast. No more 2 damage per turn. I survive. At 4 life, permanently removing Bloodghast is WAY more important than dealing 4 damage. Bloodghast would kill me in 2 turns otherwise. Let me cast Deadly Cover-Up:

It requires me to either select more or cancel. Since "required" is false and I have 6 MV already, I think I need to cancel to stop adding more (which doesn't cancel the whole evidence, just stops adding). Wait, but it cancelled before... Let me re-read. Oh wait, maybe I need to select a 3rd card or the system expects a specific interaction. The message says "selected 2, min 1" and "selected mana value 6 of 6" — evidence is met.

The board wipe worked! Opponent has NO creatures. They have Bloodthorn Flail (equipment) and Monument to Endurance on the field. All 4 Bloodghasts are exiled! They have 1 card in hand (Flamewake Phoenix). I have 2 untapped lands (Gloomlake Verge and Watery Grave). I could cast one Requiting Hex, but there are no creatures to target! No point. Let me just pass to combat and then end turn.

OK so I have 3 Requiting Hex in hand and 8 untapped lands. Opponent has Flamewake Phoenix (2/2, tapped from attacking). I need to deal with it NOW or I die next turn. Let me check what Requiting Hex does:
llm
get_oracle_text(card_name=Requiting Hex)
{
  "success": true,
  "mana_cost": "{B}",
  "name": "Requiting Hex",
  "rules": [
    "As an additional cost to cast this spell, you may blight 1. (You may put a -1/-1 counteron a creature you control.)",
    "Destroy target creature with mana value 2 or less. If this spell's additional cost was paid, you gain 2 life."
  ],
  "type": "Instant"
}
thinkingOpus Valley
Requiting Hex destroys target creature with MV 2 or less. Flamewake Phoenix has MV 3 ({1}{R}{R})... let me check:
llm
get_oracle_text(card_name=Flamewake Phoenix)
{
  "success": true,
  "mana_cost": "{1}{R}{R}",
  "name": "Flamewake Phoenix",
  "rules": [
    "Flying",
    "Haste",
    "{this} attacks each combat if able.",
    "Ferocious &mdash; At the beginning of combat on your turn, if you control a creature with power 4 or greater, you may pay {R}. If you do, return this card from your graveyard to the battlefield."
  ],
  "power": "2",
  "type": "Creature — Phoenix",
  "toughness": "2"
}
thinkingOpus Valley
MV 3! Requiting Hex can only hit MV 2 or less. So I can't use it on Flamewake Phoenix. I need another plan. Let me check Monument to Endurance and Bloodthorn Flail:
llm
get_oracle_text(card_names=["Monument to Endurance","Bloodthorn Fla...)
{
  "cards": [
    {
      "mana_cost": "{3}",

    }
  ],
  "success": true
}
thinkingOpus Valley
OK, so I can't kill the Phoenix with Requiting Hex. But I CAN block it with Restless Reef! Let me animate Restless Reef and block with it. Restless Reef becomes a 4/4 with menace, so it can definitely eat a 2/2 Phoenix. But wait — Flamewake Phoenix has flying, so Restless Reef can't block it unless it has reach or flying. Hmm, does Restless Reef get any evasion abilities?
llm
get_oracle_text(card_name=Restless Reef)
{
  "success": true,
  "name": "Restless Reef",
  "rules": [
    "{this} enters tapped.",
    "{T}: Add {U}.",
    "{T}: Add {B}.",
    "{2}{U}{B}: Until end of turn, {this} becomes a 4/4 blue and black Shark creature with deathtouch. It's still a land.",
    "Whenever {this} attacks, target player mills four cards."
  ],
  "type": "Land"
}
thinkingOpus Valley
Restless Reef gets deathtouch but NOT flying or reach, so it can't block Flamewake Phoenix. Let me look at my graveyard for Winternight Stories - it can be used from the graveyard with Harmonize:
llm
get_oracle_text(card_name=Winternight Stories)
{
  "success": true,
  "mana_cost": "{2}{U}",
  "name": "Winternight Stories",
  "rules": [
    "Draw three cards. Then discard two cards unless you discard a creature card.",
    "Harmonize {4}{U} (You may cast this card from your graveyard for its harmonize cost. You may tap a creature you control to reduce that cost by {X}, where X is its power. Then exile this spell.)"
  ],
  "type": "Sorcery"
}
thinkingOpus Valley
Harmonize costs {4}{U} = 5 mana. I have 8 lands. I could use that to draw 3 cards and potentially find removal. But it's a sorcery so I need to do it now. Actually wait - the choices showed Winternight Stories and Restless Reef are playable. Let me think about my line: I have 8 untapped lands. I need to find an answer to Flamewake Phoenix. Drawing 3 cards with Winternight Stories Harmonize seems good - it costs 5 mana, leaving me with 3 mana. Let me do that first. Actually, I should also think about attacking with Restless Reef. It costs 4 to animate (2UB). If I animate and attack, I can mill them and deal 4 damage. But I need to survive their next turn too. Let me Harmonize Winternight Stories first to draw 3, then evaluate.

I drew 3 cards: Deceit (creature 5/5, costs {4}{U/B}{U/B}), Insatiable Avarice, and Doomsday Excruciator (6/6, costs {B}{B}{B}{B}{B}{B}). I have creatures I could discard! I should discard a creature to save myself from discarding 2 cards. Let me check Deceit and Doomsday Excruciator:
llm
get_oracle_text(card_names=["Deceit","Doomsday Excruciator"])
{
  "cards": [
    {
      "mana_cost": "{4}{U/B}{U/B}",

    }
  ],

Deceit is an Elemental Incarnation! And Doomsday Excruciator costs 6 black which is very hard to cast. I should discard a creature card. I'll discard Doomsday Excruciator since I can't easily cast it (need BBBBBB). Let me say yes to discarding a creature instead of 2 cards:

  "next_action_hint": "Call get_action_choices or choose_action to see details, or pass_priority to continue.",
  "success": true,
  "action_taken": "yes"
}
thinkingOpus Valley
I'll discard Doomsday Excruciator - can't cast it, and Deceit is actually useful (evoke for {U/B}{U/B} = 2 mana to bounce their Phoenix!):
mcpDoomsday Excruciator

choose_action(id=p59)

  "next_action_pending": true,

  "next_action_hint": "Call get_action_choices or choose_action to see details, or pass_priority to continue.",
  "success": true,
  "action_taken": "selected_target_1"
}
thinkingOpus Valley
Wait, Deceit shows as castable with 3 untapped lands? It costs {4}{U/B}{U/B} = 6 mana. But the evoke cost is {U/B}{U/B} = 2 mana! Yes, I can evoke it for 2 mana to bounce Flamewake Phoenix! This is amazing. I evoke Deceit, bounce Flamewake Phoenix, and then I have a clear board. Let me cast it:
mcpCast Deceit {4}{U/B}{U/B}
raw
choose_action(id=p57)
{
  "next_action_pending": true,
  "next_action_type": "GAME_CHOOSE_CHOICE",

  "success": true,

mcpCast with Evoke alternative cost: {U/B}{U/B} (source: Deceit)

}
thinkingOpus Valley
I need {U/B}{U/B}. I want to produce blue to trigger the bounce effect ("if {U}{U} was spent to cast it, return up to one other target nonland permanent to its owner's hand"). Let me produce blue:
mcp1. {T}: Add {U}.

Deceit is on the stack with evoke. Let me pass priority to resolve it:

Flamewake Phoenix is still on the battlefield! But Deceit went to the graveyard. Hmm - wait. The U/B hybrid mana I paid with blue... did the bounce trigger happen? Maybe the opponent had 1 card in hand and I chose not to target? Let me check the log:

  "log": "y draws three cards\nOpus Valley discards Doomsday Excruciator (source: Winternight Stories)\nOpus Valley paid for Winternight Stories - Discard a creature card instead of discarding two cards?\nOpus Valley moves Winternight Stories from stack to the exile zone\nOpus Valley casts Deceit with Evoke from hand\nOpus Valley puts Deceit from stack onto the Battlefield\nOpus Valley - Ability triggers: Deceit - When this permanent enters, if its evoke cost was paid, its controller sacrifices it.\nOpus Valley sacrificed Deceit (source: Deceit)",

I see - the evoke triggered sacrifice, but there's no mention of the bounce trigger. The {U/B} hybrid produced blue, but maybe I needed {U}{U} specifically (two blue mana, not hybrid). Let me re-read: "if {U}{U} was spent to cast it" - I only paid {U/B}{U/B} = 2 hybrid mana. I tapped Gloomlake Verge for U and Watery Grave for... let me check. Actually I only chose one mana source manually. The auto-tap may have produced black for the second pip. Ugh, the bounce didn't happen because I needed BOTH pips to be blue ({U}{U} spent). That's a misplay on my part. OK, Flamewake Phoenix is still there. I'm at 2 life with 1 untapped Watery Grave. I can cast Insatiable Avarice for {B} to search for an answer!

Let me cast Insatiable Avarice. I can use it as a tutor (pay 3 more to search) or just draw 3 and lose 3 life. Wait, I'm at 2 life - I can't afford to lose 3. Let me check the modes:
llm
get_oracle_text(card_name=Insatiable Avarice)
{
  "success": true,
  "mana_cost": "{B}",
  "name": "Insatiable Avarice",
  "rules": [
    "Spree (Choose one or more additional costs.): + {2} &mdash; Search your library for a card, then shuffle and put that card on top.: + {B}{B} &mdash; Target player draws three cards and loses 3 life.: "
  ],
  "type": "Sorcery"
}
thinkingOpus Valley
OK so the base cost is {B}, plus {2} to tutor. I have 1 untapped Watery Grave. I can only pay {B} + {2} = 3 mana total, but I only have 1 untapped land. Wait, the choices said Insatiable Avarice is castable - let me just try it with the tutor mode for {B} + {2} = 3 mana. But I only have 1 untapped land! Hmm, actually it said I can cast it with 1 untapped land. The base spree lets me choose just the {2} mode for total {B}+{2}=3 mana. But I only have 1 land untapped. Unless the base cost of {B} alone with just the first mode... wait, I need to re-read. Spree says "Choose one or more additional costs" - so {B} is the base cost, and I choose which modes to add. If I just choose the tutor mode, it's {B} + {2} = 3 total. That's too much. Actually wait - can I just cast it for {B} alone? No, spree requires choosing at least one mode. So minimum is {B} + {2} = 3 mana. But the game says it's castable with 1 untapped land... maybe I'm wrong. Let me just try:
mcpCast Insatiable Avarice {B}

What? Insatiable Avarice wasn't cast? It seems like the mana payment failed and it was cancelled. I must not have had enough mana (needed {B} + {2} = 3 total, only had 1 land). The game auto-cancelled it. OK so we're in combat. I skipped attack apparently. Let me continue:
