I need to choose which player goes first. I'm DSV3 Libby (the librarian). In Magic, the player who goes first has a slight advantage by playing first, but also has the drawback of not drawing a card on their first turn.
Strategically, going first is generally preferred in most formats because you get to deploy threats first and potentially establish board control. I'll choose myself to go first.

It seems my previous response may not have been properly processed. Let me try a different approach. Looking at the response, I need to choose a starting player. The options show:
- index 0, id "p1": DSV3 Libby (me)
- index 1, id "p2": Qwen3 Undrdog (opponent)
I'll choose by index this time.

Good! Now I need to handle the pending GAME_ASK. Let me get the action choices to see what's being
thinkingDSV3 Libby
I need to evaluate my hand. Let's see: I have 3 lands (Blood Crypt and 2 Multiversal Passages), Bitter Triumph (1B), Tersa Lightshatter (2R), Bloodghast (BB), and Greasewrench Goblin (R).
Analysis:
- Blood Crypt is a dual land (B/R)
- Multiversal Passage is a conditional land (enters tapped unless you control a Gate)
- I have 2 black cards requiring BB (Bloodghast) and 1B (Bitter Triumph)
- I have 2 red cards requiring 2R and R
- I have 3 lands but 2 are conditional (might enter tapped)
- I can cast Greasewrench Goblin on turn 1, but my other spells need more specific mana
This hand has potential mana issues with the Multiversal Passages possibly entering tapped, and I need specific colors for my spells. However, I have a turn 1 play (Goblin) and decent curve. The conditional lands concern me - if they enter tapped, I could be delayed.
Given this is a 20-life format and it's my first turn, I should probably keep. I have playable cards and some flexibility. I'll answer false (NO KEEP).

I see my choice wasn't processed. Let me make the mulligan decision again. Looking at my hand, I have:
- Blood Crypt (dual land)
- 2x Multiversal Passage (conditional land that enters tapped unless I control a Gate)
- Bitter Triumph (1B - instant removal/discard)
- Tersa Lightshatter (2R - 3/3 creature)
- Bloodghast (BB - 2/1 with landfall recursion)
- Greasewrench Goblin (R - 2/1)
The hand has a turn 1 play (Goblin), but the mana is awkward with 2 conditional lands. If both Multiversal Passages enter tapped, I might be delayed on my curve. However, I'm on the play and have a 2/1 for R. Bloodghast requires BB which might be hard with this mana base.
I think it's borderline but keepable. I'll KEEP (answer=false).

Great! I kept my hand and now I'm in my main phase. I need to play a land. I have three land options:
1. Blood Crypt (p3) - RB dual land
2. Multiversal Passage (p4) - enters tapped unless I control a Gate
3. Multiversal Passage (p5) - same
Since I'm on turn 1 and don't control any Gates yet, Multiversal Passage will enter tapped. I should play Blood Crypt first since it can enter untapped and provide both black and red mana immediately. This allows me to potentially play my Greasewrench Goblin this turn.
I'll play Blood Crypt.

I need to decide whether to pay 2 life for Blood Crypt to enter untapped. Since it's turn 1 and I have only 20 life, paying 2 life is significant. However, having an untapped land on turn 1 is valuable to potentially play my Greasewrench Goblin.
Considering I have other lands (Multiversal Passages) that might enter tapped, having at least one untapped source is important. I'll pay the 2 life to keep tempo.

Interesting! It looks like it's now turn 2 (T2 Precombat Main) and I have land options. I also have a new card "Starting Town" in my hand (p11) along with my two Multiversal Passages (p4, p5).
Let me check what Starting Town does since I'm not familiar with it.

]
}thinkingDSV3 Libby
Perfect! Starting Town enters untapped on turns 1-3, then taps for colorless or can pay 1 life for any color mana. Since it's turn 2, it will enter untapped. This is better than Multiversal Passage which would enter tapped (since I don't control a Gate).
I also have a land drop available. I should play Starting Town (p11) since it enters untapped and gives me mana flexibility.

Good! I have two playable spells:
1. Bloodghast (BB) - 2/1 with landfall recursion ability
2. Bitter Triumph (1B) - instant removal/discard
I have 2 untapped lands. Bloodghast requires BB which I can get from Blood Crypt (B/R) and Starting Town (can pay 1 life for black). Let me check Bloodghast's ability to understand its value.

I need to confirm my attackers. I have Greasewrench Goblin (p9) attacking. The opponent has Steam Vents tapped (just played this turn). They're at 20 life, I'm at 18. I should confirm my attackers.
However, I see I have Bitter Triumph playable. Since I'm declaring attackers, I can cast it before blockers are declared. But let me first confirm my attackers, then consider playing Bitter Triumph.

Now I'm in my postcombat main phase on turn 2. I have 2 untapped lands (Blood Crypt and Starting Town) and 18 life. My opponent is at 18 life after my Greasewrench Goblin attacked successfully. I can play either Bloodghast (BB) or Bitter Triumph (1B).
Bloodghast is a 2/1 with a useful recursion ability that lets me bring it back from the graveyard when a land enters the battlefield. However, it requires exactly BB which might be mana intensive. Bitter Triumph is an instant removal spell that can also be used as discard.
Since I'm in postcombat main and have no immediate threats to remove, I should play Bloodghast to develop my board presence. Having a 2/1 creature adds pressure and Bloodghast's recursion ability makes it resilient. I'll cast Bloodghast.

I need to choose a mana ability for one of my lands. Let me check what options I have.
thinkingDSV3 Libby
For Bloodghast (BB), I need two black mana. I have Blood Crypt which can produce {B} or {R}, and Starting Town which can produce {C} or pay 1 life for any color.
I should:
1. Use Starting Town's second ability: pay 1 life to add {B}
2. Use Blood Crypt to add {B}
That costs me 1 life (down to 17) and gives me BB for Bloodghast.

Now it's turn 3 precombat main. I have my land drop available. Looking at my hand:
- Bloodghast (BB) - still playable (I have Blood Crypt and Starting Town that can produce BB)
- Mountain (p14) - new land card
- Multiversal Passage (p4, p5) - land cards
- Bitter Triumph (1B) - removal/discard
- Tersa Lightshatter (2R) in hand but not shown as playable yet
I should play my land for turn. Since I have a Mountain and two Multiversal Passages, I should check which is best. Multiversal Passage enters tapped unless I control a Gate, and I don't have any Gates. So it would enter tapped. Mountain enters untapped. Playing Mountain gives me access to red mana for Tersa Lightshatter (2R) which could be useful next turn.
I'll play the Mountain (p14) since it enters untapped and gives me more mana flexibility.

Good! Now with Mountain played, I have access to red mana. I can see Tersa Lightshatter (2R) is now playable, and I can also activate Greasewrench Goblin's ability.
Let me check Tersa Lightshatter's abilities:
llmget_oracle_text(object_id=p7)
{
"success": true,
"name": "Tersa Lightshatter",
"rules": [
"Haste",
"When {this} enters, discard up to two cards, then draw that many cards.",
"Whenever {this} attacks, if seven or more cards are in your graveyard, exile a card at random from your graveyard. You may play that card this turn."
]
}thinkingDSV3 Libby
Tersa Lightshatter is a 3/3 with haste that lets me loot when it enters (discard up to 2, draw that many) and has a graveyard payoff ability. Since I'm playing a RB aggressive deck, this seems like a good play.
I have 3 untapped lands: Blood Crypt (BR), Starting Town (C or pay 1 life for any color), and Mountain (R). I need {2}{R} for Tersa Lightshatter. I can use:
1. Mountain for {R}
2. Blood Crypt for {R}
3. Starting Town for the second {R} (paying 1 life)
That would cost 1 life (down to 16) but give me a 3/3 haste creature with looting ability. That's a strong turn 3 play.
Alternatively, I could cast Bitter Triumph or activate Greasewrench Goblin's ability.
Let me check Greasewrench Goblin's ability:
llmget_oracle_text(object_id=p9)
{
"success": true,
"name": "Greasewrench Goblin",
"rules": [
"Exhaust — {2}{R}: Discard up to two cards, then draw that many cards. Put a +1/+1 counter on {this}. (Activate each exhaust ability only once.)"
]
}thinkingDSV3 Libby
Perfect! Now I have several options:
1. **Bloodghast (BB)** - 2/1 creature with landfall recursion
2. **Bitter Triumph (1B)** - Instant removal/discard
3. **Tersa Lightshatter (2R)** - 3/3 Haste with card filtering and potential late-game value
4. **Greasewrench Goblin ability (2R)** - Discard up to 2, draw that many, +1/+1 counter
I have 3 untapped lands: Blood Crypt (B/R), Starting Town (C or any color for 1 life), and Mountain (R). I'm at 17 life.
I should prioritize developing my board. Tersa Lightshatter is a 3/3 haste creature for 2R - that's strong on turn 3. It also provides card filtering on ETB, which could be useful since I have 5 cards in hand including some lands. Let me cast it.

I see what happened - p19 was not a valid attacker ID. Looking at the state, I only have Greasewrench Goblin (p9) on the battlefield. Tersa Lightshatter (p7) is still in my hand - it seems my casting of it earlier didn't complete or there was an issue. Let me check the game log to see what happened:

Now I'm in the declare blockers step and can play instants or activate abilities. I have Bitter Triumph (1B) available as an instant, and I can activate Greasewrench Goblin's ability (2R) to discard up to 2 cards and draw that many, putting a +1/+1 counter on it.
My opponent is at 18 life, I'm attacking with a 2/1 Greasewrench Goblin. If they don't block, they go to 16. I could activate Greasewrench Goblin's ability to make it a 3/2, which might be relevant if they have a blocker. But I should wait to see if they block first.
I'll pass priority for now and see if they block or cast anything.

Great! My attack got through - opponent is now at 16 life (down from 18). I'm now in combat damage step. I can activate Greasewrench Goblin's ability at instant speed during combat damage to get a +1/+1 counter and filter my hand. Since I have 5 cards in hand (2 Multiversal Passages, Bitter Triumph, Tersa Lightshatter, Bloodghast), I could discard some lands and draw into more action.
But actually, I should wait until after combat to activate it, unless I need the +1/+1 counter right now for combat. The damage is already dealt, so the counter won't affect this combat. Better to wait for my second main phase.
I'll pass for now.

Now I'm in postcombat main phase. I should consider my options:
1. **Bloodghast (BB)** - Still playable, would give me another creature
2. **Bitter Triumph (1B)** - Removal/discard
3. **Tersa Lightshatter (2R)** - 3/3 Haste with card filtering
4. **Greasewrench Goblin ability (2R)** - Filter cards and get +1/+1 counter
I have 3 untapped lands: Blood Crypt (B/R), Starting Town (C or any for 1 life), and Mountain (R). I'm at 17 life.
I think the best play is to cast Tersa Lightshatter (2R) for a 3/3 haste creature. It provides immediate board presence and card filtering when it enters. The filtering is valuable since I have 2 Multiversal Passages in hand (enters tapped lands) that I might want to discard.
Let me cast Tersa Lightshatter.

}thinkingDSV3 Libby
I need to choose a mana ability for one of my lands. Let me think: Tersa Lightshatter costs {2}{R}. I have 3 untapped lands:
- Blood Crypt (can produce B or R)
- Starting Town (C or pay 1 life for any color)
- Mountain (R)
I should use:
1. Mountain for {R}
2. Blood Crypt for {R}
3. Starting Town for {R} (paying 1 life)
That gives me RRR which covers the {2}{R} cost. Actually, {2}{R} means I need 2 generic mana and 1 red mana. I can produce:
- Mountain: {R}
- Blood Crypt: {R}
- Starting Town: {C} (colorless) or pay 1 life for {R}
I need 3 total mana: 1 red and 2 of any color. So I could do:
- Mountain: {R}
- Blood Crypt: {R} (this counts as 1 red)
- Starting Town: {C} (colorless for 1 generic)
That's R (from Mountain) + R (from Blood Crypt) + C (from Starting Town) = RR + C = 2 red + 1 colorless = covers {2}{R} (needs 1 red + 2 generic).
Actually, "generic" mana can be paid with any color or colorless. So RR + C works: R counts as both red mana for the {R} requirement and also counts toward generic costs. With RR + C, I have 2 red mana and 1 colorless. One red satisfies the {R} requirement, the other red and the colorless satisfy the {2} generic requirement.
Let me activate Mountain first:

Tersa Lightshatter is on the battlefield, its ETB triggered ability is on the stack. I need to resolve it - I need to choose how many cards to discard (up to 2). Let me check what cards are in my hand: Multiversal Passage (x2), Bitter Triumph, Bloodghast.
I have 4 cards in hand. I should discard up to 2 cards to draw that many. I have two Multiversal Passages (enters tapped unless I control a Gate) - I don't have any Gates, so they enter tapped. I'm playing an aggressive RB deck, so I might want to discard one or both to draw into more action.
I could discard 1 Multiversal Passage to draw 1 card, or discard 2 to draw 2. Since I already have 3 lands on board, I don't need more lands that enter tapped. Let me discard both Multiversal Passages to draw 2 new cards.
Actually, I need to see how this resolves. The ability says "discard up to two cards, then draw that many cards." I should choose to discard 2 cards.

I need to select cards to discard. The ability says "discard up to two cards". I can select 0, 1, or 2 cards. I'll discard both Multiversal Passages (p4 and p5) since they're lands that enter tapped and I already have enough mana sources.

Excellent! My Tersa Lightshatter's ability resolved, I discarded 2 Multiversal Passages and drew 2 cards: Mountain (p20) and Flamewake Phoenix (p21), plus I drew Inti, Seneschal of the Sun (p22) on my draw step. I also played Inti from my hand.
Now my board state is very strong:
- Greasewrench Goblin (2/1)
- Tersa Lightshatter (3/3 with haste - can attack immediately!)
- Inti, Seneschal of the Sun (2/2 with summoning sickness)
Inti gives all my attacking creatures +1/+0 until end of turn when they attack! So I have a great attack:
- Greasewrench Goblin: 2/1 → 3/1 with Inti
- Tersa Lightshatter: 3/3 → 4/3 with Inti
That's 7 damage total! Opponent is at 16 life, so if they don't block, they go to 9.
In hand, I have:
- Bitter Triumph (1B) - removal that can also be used for card selection
- Bloodghast (BB) - 2/1 that can return from graveyard when a land enters
- Flamewake Phoenix (1RR) - 2/2 flying that can return from graveyard when a creature with power 2+ attacks
- Mountain - land
I have 1 untapped Mountain (p20) available to play. My other lands (Blood Crypt, Starting Town) are tapped from last turn's plays.
I should play my Mountain, then attack with both creatures. Let me play the Mountain first.

Great! Inti's triggered ability is on the stack: "Whenever you attack, you may discard a card. When you do, put a +1/+1 counter on target attacking creature. It gains trample until end of turn." This is a "may" ability, so I can choose to use it or not.
I should consider discarding a card to put a +1/+1 counter on one of my attackers. Looking at my hand:
- Bitter Triumph (1B) - removal, could be useful
- Bloodghast (BB) - can come back from graveyard if I have a land enter, but I already played my land for turn
- Flamewake Phoenix (1RR) - can come back from graveyard if I have a creature with power 2+ attack
Actually, Bloodghast can return from my graveyard when a land enters the battlefield under my control. Since I already played my land for turn, it won't come back this turn. But I could discard Bloodghast, then it will be in my graveyard ready to come back if I draw a land next turn.
Flamewake Phoenix can return from my graveyard if I have a creature with power 2 or greater attack. I have Tersa Lightshatter (3/3) and Greasewrench Goblin (2/1) attacking, so Flamewake could come back next combat if I discard it now. However, I don't have RR to cast it from my hand if I need it this turn, and discarding it to Inti's ability puts it in my graveyard where I can return it for free when a creature with power 2+ attacks.
Actually wait, reading Inti's ability more carefully: "Whenever you attack, you may discard a card. When you do, put a +1/+1 counter on target attacking creature. It gains trample until end of turn." It has two parts:
1. "you may discard a card" - this is optional
2. "When you do" (when you discard a card), put a +1/+1 counter...
So I can choose to discard a card, and if I do, I get to put a +1/+1 counter on an attacking creature. The discard is part of the cost.
I have 3 cards in hand. I could discard Bloodghast since I can't cast it this turn anyway (BB cost, I have 2 Mountains untapped but no Black sources untapped). Or I could discard Bitter Triumph if I think I won't need removal this turn. Or Flamewake Phoenix.
Actually, looking at my board: I have 2 attackers, Greasewrench Goblin (2/1) and Tersa Lightshatter (3/3). With Inti's static ability, they get +1/+0 when attacking, so they're currently 3/1 and 4/3. If I put a +1/+1 counter on Greasewrench Goblin, it becomes a 4/2 with trample (after Inti's +1/+0). That's nice.
But if I put the counter on Tersa Lightshatter, it becomes a 5/4 with trample. That's even better. However, the opponent has no blockers, so trample doesn't matter. The +1/+1 counter is permanent though, so I should put it on whichever creature I think will be more valuable long-term.
Greasewrench Goblin has the exhaust ability (2R: discard up to two cards, then draw that many cards and put a +1/+1 counter on Greasewrench Goblin). So it can grow itself over time. Tersa Lightshatter doesn't have any growth ability.
I think I should discard Bloodghast and put the counter on Tersa Lightshatter to make it a 4/4 (or 5/4 with Inti's bonus). Bloodghast is fine in the graveyard - it can come back when a land enters.

I need to choose which ability goes on the stack first. This is for the "when you do" triggered ability from Inti. Let me check what the abilities are:
p24 and p25 are both "Ability" cards. Probably they represent the two parts of Inti's ability. The first ability is "Whenever you attack, you may discard a card." The second is "When you do, put a +1/+1 counter on target attacking creature. It gains trample until end of turn."
I discarded Bloodghast, so now the "when you do" triggered ability should go on the stack. Let me choose p24 (first one).

Excellent! The opponent dropped from 16hp to 10hp! That means my attackers dealt 6 damage total. Let me check what happened:
Greasewrench Goblin: 2/1 base, +1/+0 from Inti = 3/1
Tersa Lightshatter: 3/3 base, +1/+1 counter from Inti = 4/4, +1/+0 from Inti = 5/4
Total: 3 + 5 = 8 damage, but opponent only took 6 damage. That means they blocked something! Let me check the game state.

Good! I see my Tersa Lightshatter now has a +1/+1 counter and is 4/4 (base 3/3 + counter). It got trample from Inti's ability until end of turn.
The opponent is at 10 life. My Greasewrench Goblin is 2/1 base but should be 3/1 with Inti's bonus when attacking. My Tersa Lightshatter is 4/4 base but should be 5/4 with Inti's bonus when attacking. But looking at the combat state, it shows them as 2/1 and 4/4, not counting Inti's +1/+0 bonus. Maybe Inti's bonus is applied in combat damage calculation but not shown in the display.
Wait, the opponent lost 6 life (from 16 to 10), not 8. That means one of my creatures was blocked or didn't deal damage. Let me check if there was a blocker I missed. The combat section shows both attackers as "blocked: false", so they weren't blocked. Maybe the opponent cast a spell that prevented damage or gained life?
Actually, looking at the board, I have 2 untapped Mountains. I could cast Flamewake Phoenix (1RR) or Bitter Triumph (1B) during combat damage step if I wanted to. But I should pass priority and let damage resolve.

Now I'm in postcombat main phase. I have 2 untapped Mountains (p14 and p20) and 2 cards in hand: Bitter Triumph (1B) and Flamewake Phoenix (1RR). I can't cast Bitter Triumph because I have no black mana available (both Mountains are red). I could cast Flamewake Phoenix with my 2 Mountains (RR) but need one more red mana. Actually Flamewake costs 1RR, so I need 3 total mana: 1 generic + RR. I have only 2 Mountains, so I can't cast it either.
But wait, I have Starting Town (tapped) and Blood Crypt (tapped). Blood Crypt can produce B or R. So next turn I'll have black mana available.
Actually, I just realized I have Bloodghast in my graveyard! I discarded it to Inti's ability. Bloodghast is a 2/1 that can return from my graveyard to the battlefield when a land enters the battlefield under my control. But I already played my land for turn, so I won't get it back this turn.
I should pass to end my turn.

Interesting! It's now turn 5, my precombat main phase. My life dropped from 17 to 15 - I must have taken 2 damage from something. Probably from Blood Crypt's "enters the battlefield tapped unless you pay 2 life" - but I played it earlier. Maybe opponent cast something?
I drew a new card: Bloodthorn Flail (p28) with mana cost {B}. That's a cheap black spell I can cast. I also have Flamewake Phoenix (1RR), Bitter Triumph (1B), and can activate Greasewrench Goblin's ability.
My lands:
- Blood Crypt (tapped? Let me check... p3 is tapped)
- Starting Town (tapped? p11 is tapped)
- Mountain (p14 untapped)
- Mountain (p20 untapped)
- Plus I have a land drop this turn!
Wait, the game shows "land_drops_used":0, so I can play a land. I need to see what lands I have available to play. Let me check my hand size and what cards I have.
Actually, looking at the state: I have 2 cards in hand (Bitter Triumph p6, Flamewake Phoenix p21). But the choices show Bloodthorn Flail p28 is in my hand too. So I have 3 cards in hand? Let me check more carefully.
From the game state earlier: I had 2 cards in hand (Bitter Triumph, Flamewake Phoenix). Now I drew Bloodthorn Flail on my draw step, so I have 3 cards. Good.
My mana situation: 2 untapped Mountains (RR). Bloodthorn Flail costs {B} - I need black mana. I have Blood Crypt which can produce B or R. It's currently tapped. I can tap one Mountain to pay for Bloodthorn Flail's {B}? No, Mountains only produce R. I need a black source.
Wait, I also have Starting Town which is a land with "{T}: Add {C}" (colorless). So I have: Blood Crypt (tapped, BR dual), Starting Town (tapped, colorless), 2 Mountains (untapped, RR).
If I untap, all my lands untap. Let me see the board state after untap step:
Actually, I'm in precombat main phase on turn 5. My lands should have untapped during my untap step. Let me check if Blood Crypt and Starting Town are untapped now.
Looking at the battlefield list:
- Blood Crypt p3 (tapped: true)
- Starting Town p11 (tapped: true)
- Mountain p14 (tapped: false)
- Mountain p20 (tapped: false)
Hmm, they're still tapped. Maybe the game state hasn't updated visually? Or maybe they don't untap because of some effect? Let me check if there's a "doesn't untap" effect.
Actually, I attacked with Greasewrench Goblin and Tersa Lightshatter last turn, so they're tapped. But lands should untap during untap step. Unless... did I miss my untap step? No, we went from combat damage to postcombat main to opponent's turn to my turn 5 precombat main. Lands should untap.
Let me check if there's something preventing lands from untapping. Actually, looking more carefully: Blood Crypt and Starting Town are listed as tapped, but maybe that's from last turn's state and they actually untapped? The "untapped_lands":4 suggests I have 4 untapped lands!
Yes! "untapped_lands":4 means I have 4 untapped lands. So Blood Crypt and Starting Town must have untapped. The display might be showing outdated tapped status.
So I have: Blood Crypt (can produce B or R), Starting Town (colorless), 2 Mountains (R each). Total: 4 lands, 4 untapped.
I can cast Bloodthorn Flail for {B} using Blood Crypt. I can cast Bitter Triumph for {1}{B} using Blood Crypt + Mountain. I can cast Flamewake Phoenix for {1}{R}{R} using 2 Mountains + Starting Town or Blood Crypt.
What does Bloodthorn Flail do? Let me get its oracle text.
llmget_oracle_text(object_id=p28)
{
"success": true,
"name": "Bloodthorn Flail",
"rules": [
"Equipped creature gets +2/+1.",
"Equip—Pay {3} or discard a card."
]
}thinkingDSV3 Libby
Bloodthorn Flail is an Equipment that gives +2/+1. Equip cost: Pay {3} or discard a card. That's interesting! I can cast it for {B}, then equip it by discarding a card (which would put Flamewake Phoenix in my graveyard where it can potentially return).
But I should think about my overall plan. Opponent is at 10 life. I have:
- Greasewrench Goblin (2/1, tapped from attacking)
- Tersa Lightshatter (4/4 with +1/+1 counter, tapped from attacking)
- Inti, Seneschal of the Sun (2/2, summoning sickness)
- 4 lands
I can attack next turn with Inti (2/2) and maybe equip it with Bloodthorn Flail to make it a 4/3. Or equip Tersa Lightshatter to make it a 6/5.
Actually, Tersa Lightshatter has haste! It can attack the turn it enters. So if I cast Bloodthorn Flail and equip it to Tersa Lightshatter, Tersa becomes a 6/5 with haste and can attack this turn! Plus with Inti's +1/+0 when attacking, it would be 7/5.
Wait, Tersa Lightshatter is already on the battlefield and tapped from attacking last turn. It won't untap until my next untap step. So I can't attack with it this turn.
Inti has summoning sickness, so it can't attack this turn either.
Greasewrench Goblin is tapped.
So I have no attackers this turn. But I can develop my board: cast Bloodthorn Flail, maybe cast Flamewake Phoenix if I have the mana.
Flamewake Phoenix is 2/2 flying, haste. It can attack this turn if I cast it! And it has "Whenever one or more creatures you control with power 2 or greater attack, you may pay {R}. If you do, return Flamewake Phoenix from your graveyard to the battlefield tapped and attacking."
So if I cast Flamewake Phoenix now (needs 1RR), it can attack this turn as a 2/2 flying. With Inti's +1/+0 when attacking, it becomes 3/2 flying. That's decent pressure.
But I need 3 mana: 1RR. I have 4 lands: Blood Crypt (B/R), Starting Town (C), Mountain (R), Mountain (R). I could use Blood Crypt for R, both Mountains for R, Starting Town for the generic mana. That works.
Alternatively, I could cast Bloodthorn Flail (B) and equip it to Inti by discarding Flamewake Phoenix. Then Inti becomes a 4/3. But Inti can't attack this turn due to summoning sickness.
Hmm, I think casting Flamewake Phoenix is better because:
1. It can attack immediately (haste)
2. It's a flyer, opponent likely has no flying blockers
3. It puts pressure on opponent's 10 life
4. If it dies, it can potentially come back from graveyard when I attack with a creature power 2+
Let me cast Flamewake Phoenix.

Excellent! Flamewake Phoenix resolved and entered the battlefield. Now it's combat phase and I need to declare attackers. I have 3 potential attackers:
1. Greasewrench Goblin (2/1) - tapped from last turn's attack, but should have untapped during my untap step
2. Tersa Lightshatter (4/4 with +1/+1 counter) - tapped from last turn's attack, should have untapped
3. Inti, Seneschal of the Sun (2/2) - has summoning sickness, cannot attack
4. Flamewake Phoenix (2/2 flying, haste) - just cast this turn, has haste, can attack
The list shows 4 choices: Greasewrench Goblin, Tersa Lightshatter, Inti, and "All attack". But Inti has summoning sickness and shouldn't be attackable. Maybe the game is letting me choose it but it would be an illegal attack? Actually, Inti entered this turn (I cast it last turn on turn 4), so it doesn't have summoning sickness anymore! It's been under my control since the beginning of my last turn, so it can attack this turn.
Wait, I cast Inti on turn 4, and now it's turn 5. Inti doesn't have summoning sickness! So I can attack with Inti too.
Flamewake Phoenix already appears in "already_attacking" - that's weird. Maybe it automatically attacks because it has haste and entered this turn? Or maybe there's some triggered ability?
Looking at the "already_attacking" field, it shows Flamewake Phoenix is already attacking. That must be because of its ability or some other effect. Actually, looking at Flamewake Phoenix's rules: "Whenever one or more creatures you control with power 2 or greater attack, you may pay {R}. If you do, return Flamewake Phoenix from your graveyard to the battlefield tapped and attacking."
But Flamewake Phoenix is already on the battlefield, not in my graveyard. So why is it already attacking? Maybe it's a display bug or I'm misunderstanding.
Let me check what creatures can actually attack:
- Greasewrench Goblin: can attack
- Tersa Lightshatter: can attack
- Inti: can attack
- Flamewake Phoenix: shows as already attacking
I should attack with all creatures that can deal damage. Opponent is at 10 life. Let me calculate damage:
With Inti's ability "Attacking creatures you control get +1/+0":
- Greasewrench Goblin: 2/1 base → 3/1 when attacking
- Tersa Lightshatter: 4/4 base → 5/4 when attacking
- Inti: 2/2 base → 3/2 when attacking
- Flamewake Phoenix: 2/2 flying base → 3/2 flying when attacking
Total damage: 3 + 5 + 3 + 3 = 14 damage, opponent at 10 life. That's lethal!
But wait, Flamewake Phoenix is already listed as attacking. So if I attack with the other 3, that's 3 + 5 + 3 = 11 damage, plus Flamewake's 3 = 14 total. That's lethal.
However, I need to consider if opponent has any blockers or instant-speed interaction. They have 2 lands untapped (Steam Vents and Riverpyre Verge). They could have a trick or removal.
Actually, looking at opponent's graveyard: they have Opt and Bounce Off. Bounce Off is a blue instant that can bounce a creature and draw a card. That could remove one of my attackers. But they'd need blue mana. Steam Vents can produce U or R, Riverpyre Verge is probably a land that can produce U or B. So they could have blue mana open.
If they bounce my Tersa Lightshatter (5/4), that's 5 damage prevented. Then I'd deal 3 (Greasewrench) + 3 (Inti) + 3 (Flamewake) = 9 damage, opponent goes to 1 life.
But they could also have other spells. They're at 10 life with 4 cards in hand.
I should attack with everything. If they have Bounce Off, they can only bounce one creature. I still have lethal even if they bounce one (14 damage total, minus 5 if they bounce Tersa = 9, opponent at 1 life). But they might have more interaction.
Actually, wait - Flamewake Phoenix is already marked as attacking. So I just need to declare the other attackers. Let me attack with all three: Greasewrench Goblin, Tersa Lightshatter, and Inti.

Interesting! I'm being asked "Discard a card?" This must be from Inti's triggered ability: "Whenever you attack, you may discard a card. If you do, draw a card."
Since I declared attackers, Inti's ability triggers. I should discard a card to draw a card. I have Bitter Triumph (1B) and Bloodthorn Flail (B) in hand. I should discard one of them.
Which one to discard? Bloodthorn Flail is an Equipment that gives +2/+1. Bitter Triumph is removal that costs 1B and makes me lose 3 life or discard a card. Both are useful.
I think I should discard Bloodthorn Flail because:
1. I already have good creatures on board
2. Bitter Triumph can remove a potential blocker or threat
3. Equipping Bloodthorn Flail costs {3} or discarding a card, which is expensive
4. Drawing a card might give me something better
But actually, if I discard Bloodthorn Flail, I can't cast it later. But I can cast Bitter Triumph if I need removal.
Actually, I'm attacking for potentially lethal damage. If this attack succeeds, the game ends. If opponent has a trick, I might need Bitter Triumph as removal for a potential blocker. But Bitter Triumph requires me to lose 3 life or discard a card, and I'm at 15 life.
Hmm, I think discard Bloodthorn Flail and draw a card. Yes.

I need to pick which triggered ability goes on the stack first. I have two abilities triggering from attacking:
1. Inti's "Whenever you attack, you may discard a card. If you do, draw a card."
2. Flamewake Phoenix's "Whenever one or more creatures you control with power 2 or greater attack, you may pay {R}. If you do, return Flamewake Phoenix from your graveyard to the battlefield tapped and attacking."
But Flamewake Phoenix is already on the battlefield and attacking, so its ability shouldn't trigger. Maybe it's something else?
Actually, looking at the IDs: p31 and p32. These might be the two attacking triggers. One is Inti's discard/draw ability. The other might be something else - maybe from Tersa Lightshatter or Greasewrench Goblin?
Let me check what abilities my creatures have:
- Inti: "Whenever you attack, you may discard a card. If you do, draw a card."
- Tersa Lightshatter: "Haste. When Tersa Lightshatter deals combat damage to a player, you may put a +1/+1 counter on it. If you do, untap it."
- Greasewrench Goblin: "Exhaust — {2}{R}: Discard up to two cards, then draw that many cards. Activate only as a sorcery."
- Flamewake Phoenix: "Flying, haste. Whenever one or more creatures you control with power 2 or greater attack, you may pay {R}. If you do, return Flamewake Phoenix from your graveyard to the battlefield tapped and attacking."
So I have Inti's trigger and maybe Tersa's "when deals combat damage" trigger (but that hasn't happened yet). Or maybe Flamewake Phoenix's trigger is happening even though it's already attacking?
Actually, I have 3 creatures attacking with power 2 or greater (Greasewrench is 2/1, Tersa is 4/4, Inti is 2/2). So Flamewake Phoenix's ability triggers! "Whenever one or more creatures you control with power 2 or greater attack" - I have 3 such creatures attacking, so Flamewake Phoenix's ability triggers.
I need to choose the order these abilities go on the stack. Usually it doesn't matter much, but I should put Inti's ability (discard/draw) on the stack first, then Flamewake Phoenix's ability. That way, if I draw a card with Inti's ability, I might get something useful before deciding whether to pay {R} for Flamewake Phoenix's ability.
Actually, Flamewake Phoenix's ability is "you may pay {R}" - I can choose not to pay. I have 1 untapped land (a Mountain probably). I could pay {R} to return Flamewake Phoenix from graveyard, but it's already on the battlefield. So this ability does nothing useful - Flamewake Phoenix is already on the battlefield attacking.
Wait, maybe the ability still triggers but has no effect since Flamewake Phoenix isn't in my graveyard. I should choose not to pay {R}.
But I need to choose which ability goes on the stack first. I'll put Inti's ability (p31) first, then Flamewake Phoenix's ability (p32).

I need to select an attacking creature for something. This might be for Inti's ability: "Whenever you attack, you may discard a card. If you do, draw a card." That doesn't target a creature.
Or maybe it's for something else? Let me think... Perhaps it's asking which attacking creature to put a +1/+1 counter on from Tersa Lightshatter's ability? But Tersa's ability triggers when it deals combat damage, not when attacking.
Maybe it's for Inti's other ability: "If a creature you control would put one or more counters on itself, it puts that many plus one of each of those kinds of counters on itself instead." But that's a replacement effect, not a trigger.
Hmm, I'm not sure. Let me select Tersa Lightshatter (p7) since it's my biggest attacker.

Bloodghast doesn't have haste (opponent is at 20 life), so casting it pre-combat reveals unnecessary information to the opponent before the attack step. Since Bloodghast can't attack this turn anyway, it should be cast post-combat.
Analysis
Action taken: Cast Bloodghast in precombat main phase before attacking with Greasewrench Goblin
Better line: Attack with Greasewrench Goblin first, then cast Bloodghast in second main phase to avoid revealing information unnecessarily

gameDSV3 Libby puts Tersa Lightshatter from stack onto the Battlefield
gameDSV3 Libby - Ability triggers: Tersa Lightshatter - When Tersa Lightshatter enters, discard up to two cards, then draw that many cards.
minor blunder
Discarding Multiversal Passage over Bitter Triumph is suboptimal.
Discarding Multiversal Passage over Bitter Triumph is suboptimal. The player has 4 lands already and is discarding to Tersa Lightshatter's ETB to draw replacements. However, the real issue is the choice of what to discard. Bloodghast can be recurred from the graveyard via landfall, making it actively better in the graveyard than in hand. Discarding Bloodghast + one Multiversal Passage would let the player keep Bitter Triumph (premium removal) and one Multiversal Passage (to trigger Bloodghast's landfall next turn, getting a free 2/1). Instead, by discarding both lands, the player loses future land drops that could trigger Bloodghast recursion and keeps Bloodghast in hand where it must be hard-cast.
Analysis
Action taken: Discarded Multiversal Passage as the first card (planning to discard both Passages).
Better line: Discard Bloodghast and one Multiversal Passage. Bloodghast has landfall recursion from the graveyard, so it's more valuable there. Keep Bitter Triumph as removal and the remaining Multiversal Passage to play next turn, triggering Bloodghast's return to the battlefield for free.
minor blunder
Discarding two Multiversal Passages instead of keeping one as a land drop is questionable.
Discarding two Multiversal Passages instead of keeping one as a land drop is questionable. Libby has 4 lands on board, all tapped, and no lands in hand after discarding both Passages. Next turn they will miss their land drop (turn 4) unless they draw a land. Keeping one Passage and discarding either Bitter Triumph or Bloodghast instead would guarantee the turn 4 land drop. Bloodghast in particular has landfall recursion from graveyard, so discarding it is actively good - it can return when a land is played. The optimal line was to discard Bloodghast + one Multiversal Passage, keeping the other Passage for the land drop and Bitter Triumph for removal. Bloodghast in the graveyard would then return to play when the kept Passage is played next turn.
Analysis
Action taken: Discarded both Multiversal Passages to Tersa Lightshatter's ETB trigger, keeping Bitter Triumph and Bloodghast in hand.
Better line: Discard Bloodghast and one Multiversal Passage, keeping the other Passage for turn 4 land drop and Bitter Triumph for removal. Bloodghast would recur from graveyard when the Passage is played, effectively getting it for free.

gameDSV3 Libby discards Bloodghast (source: Inti, Seneschal of the Sun)
minor blunder
Inti's attack trigger allows discarding a card to put a +1/+1 counter on an attacking creature and grant trample.
Inti's attack trigger allows discarding a card to put a +1/+1 counter on an attacking creature and grant trample. The player discarded Bloodghast instead of Flamewake Phoenix. Bloodghast has landfall recursion (returns from graveyard when a land enters), but it's a 2/1 that can't block. Flamewake Phoenix has ferocious recursion (return from graveyard at beginning of combat if you control a creature with power 4+). With Tersa Lightshatter at 3 power and Inti at 2 power (before the counter), after the +1/+1 counter one of the attackers could reach 4 power, enabling Flamewake Phoenix recursion. However, the player already has Flamewake Phoenix in hand and can cast it normally for 1RR. Meanwhile, Bloodghast's recursion is more reliable (just need to play a land) and provides repeated value. Discarding Flamewake Phoenix would have been better since: (1) Inti's discard trigger exiles the top card for potential extra plays, (2) Flamewake Phoenix can recur from graveyard if they get a 4-power creature (Tersa with the counter from Inti becomes 4/4, enabling Phoenix recursion next combat), effectively giving them a free creature without spending mana to cast it from hand. Bloodghast in hand can be cast for BB and will recur from graveyard on landfall anyway, but discarding it means they need a land drop to get it back, whereas Phoenix would recur automatically with a 4-power creature.
Analysis
Action taken: Discarded Bloodghast to Inti's attack trigger
Better line: Discard Flamewake Phoenix instead. After putting the +1/+1 counter on Tersa Lightshatter (making it 4/4), Flamewake Phoenix would recur from graveyard for free (just paying R) at the beginning of combat on subsequent turns, while Bloodghast could be cast from hand for BB.

Targeting DSV3 Libby (the opponent's face) with Burst Lightning for 2 damage (17→15) instead of killing a creature is a significant misuse of removal. Inti, Seneschal of the Sun is a 2/2 that generates card advantage and pumps attackers every combat - it's the key engine piece on the opponent's board. With Qwen3 at only 10 life facing an aggressive board (Inti, Tersa Lightshatter 3/3 haste, Greasewrench Goblin, and Bloodghast in graveyard ready to return), dealing 2 damage to face accomplishes almost nothing while leaving the opponent's most dangerous synergy piece alive. Killing Inti would significantly reduce the opponent's damage output and card advantage generation.
Analysis
Action taken: Targeted DSV3 Libby (opponent's face) with Burst Lightning for 2 damage.
Better line: Target Inti, Seneschal of the Sun with Burst Lightning to kill the 2/2 engine creature that generates card advantage and combat bonuses every attack step.
