Game Log
chatOpus Hist: Keeping 7! Scalding Tarn on turn one — still one of the best fetchlands since Zendikar in 2009. Let's see what we're working with! 🔥
chatOpus Hist: Turn 1 Mako into Street Wraith cycle — that's the kind of synergy that reminds me of the old Hollow One decks from 2018 Modern. Discard payoffs never get old! 🦈
chatOpus Hist: Ah, Hollow One in the graveyard feeding the Nethergoyf — this deck feels like a love letter to the 2018 Hollow One Modern archetype! Turn 2 3/3 Mako swinging in. 🦈💪
chatOpus Hist: Bestow on a 4/4 Mako — Detective's Phoenix doing its best Rancor impression! 🕵️ Speaking of which, Rancor from Urza's Legacy, 1998... now THAT was an aura that changed everything. Phoenix here isn't far off!
chatOpus Hist: Counterspell from Alpha, 1993. The OG. Sorry, can't let you have that one! Richard Garfield's original design was so clean — UU to say "no." Timeless.
chatOpus Hist: 8/8 flying Mako incoming! Detective's Phoenix doing what Bestow creatures did best in Theros block — turning your beater into an absolute monster. Nighthowler flashbacks anyone? 😄
chatOpus Hist: GG! An 8/8 flying Mako to seal it. Bestow was always an underrated mechanic — Theros block 2013 gave us some gems. What a game! 🎉

Alright, time to choose who goes first! In competitive Magic, going first is almost always the right call — you get the tempo advantage, play your lands first, and apply pressure before your opponent can react. This has been true since Alpha in 1993, and it's still true today!

I've chosen to go first — as Richard Garfield intended! Now let's see what's next, likely the mulligan decision.
thinkingOpus Hist
Let me evaluate this hand: - **Mountain** + **Scalding Tarn** — Two lands, good mana base - **Nethergoyf** ({B}) — A classic callback to Tarmogoyf from Future Sight! Grows with card types in graveyard - **Marauding Mako** ({R}) — 1-drop that grows when we discard - **Street Wraith** — The iconic cycle-for-free card from Future Sight, a staple of Death's Shadow and Living End decks since 2007! Free card draw at 2 life - **Detective's Phoenix** x2 ({2}{R}) — Recursive hasty flyers This is a solid hand! Two lands including a fetchland (which fills the graveyard for Nethergoyf), two 1-drops, Street Wraith for free cycling, and recursive threats. Scalding Tarn can fetch for either color we need. This looks like a Rakdos/Izzet graveyard-focused deck. I'm keeping this.

Hmm, it seems the game auto-passed through my main phase without giving me a chance to play lands. We're in combat now. The only playable card showing is Street Wraith — but that's showing as a cast option (5 mana), not cycling. Wait, Street Wraith's cycling is "Pay 2 life" — it's essentially a free cycle. Let me think about whether to cycle it now. Actually, cycling Street Wraith here makes sense — it puts a creature card in the graveyard (helping Nethergoyf), triggers Marauding Mako's discard ability if Mako is on the battlefield (it's not yet), and draws us a card. But we don't have Mako on the field yet, so we'd miss that trigger. Let me think about sequencing: If I pass through combat, I can play a land in postcombat main, play Marauding Mako, then cycle Street Wraith to both draw a card and put a +1/+1 counter on Mako. That's the optimal line. Let me pass through combat for now.

}
thinkingOpus Hist
Postcombat main phase. Now let me plan the optimal sequencing: 1. Play **Mountain** (not Scalding Tarn first — I want to play Mountain, then cast Marauding Mako with it, then cycle Street Wraith to put a counter on Mako and fill graveyard for Nethergoyf) 2. Cast **Marauding Mako** with the Mountain 3. Cycle **Street Wraith** (pay 2 life, discard, draw) — triggers Mako's +1/+1 counter Wait, but Marauding Mako isn't showing as castable yet because I haven't played a land. Let me play Mountain first. Actually, let me reconsider. Should I play Scalding Tarn instead? Scalding Tarn can fetch a Mountain or an Island. If I play Scalding Tarn, I can still tap it to fetch a Mountain (untapped), giving me red mana for Mako, plus thinning my deck and putting a land in the graveyard for Nethergoyf card types. But that costs 1 life on top of the 2 life for Street Wraith cycling — 3 life total on turn 1. That's aggressive but this deck seems to want the graveyard. Actually, fetching puts a land card type in the graveyard (Scalding Tarn is a land), which helps Nethergoyf. Then cycling Street Wraith puts a creature card type in the graveyard. That's 2 card types already, making Nethergoyf a 2/3. Let me play Mountain for now — save the fetch for when I need to fix colors or need the graveyard type later. Mountain lets me cast Mako immediately without life loss.

Mako should have resolved. Now I want to cycle Street Wraith (pay 2 life, discard it, draw a card), which should trigger Mako's +1/+1 counter ability since we're discarding. But cycling isn't showing as an option — only the full cast of Street Wraith for {3}{B}{B}. The cycling should be an activated ability... Let me check if there's something I'm missing by looking at the game state.

I see — Street Wraith is showing as "playable" but only as a cast option for {3}{B}{B}. The cycling ability (pay 2 life) should also be available since it doesn't require mana. It's possible the interface is showing the cast as the only option, but cycling might be triggered by selecting the card. Let me try selecting Street Wraith and see if it gives me a choice between casting and cycling.

Excellent! Everything worked perfectly: - **Street Wraith** cycled to graveyard (creature type, making Nethergoyf a 1/2) - **Marauding Mako** got a +1/+1 counter (now 2/2) - Drew **Arena of Glory** — a great land that can produce double red! Now I have Arena of Glory in hand. Since I control a Mountain, it enters untapped. But I already used my land drop this turn. Let me pass the turn.

Not much info on the opponent's turn. They went to 18 — maybe a fetchland. Now for my turn 2: I have Arena of Glory and Scalding Tarn in hand. Let me think about what to play: - **Arena of Glory**: Enters untapped (I control a Mountain), can tap for R, or can exert for RR to cast a creature with haste - **Scalding Tarn**: Fetch for an Island or Mountain I should play **Arena of Glory** this turn. With Mountain + Arena of Glory, I have 2 red mana. I could: 1. Cast Detective's Phoenix for {2}{R} — but that needs 3 mana total (2 generic + 1 red), and I only have 2 lands 2. Wait... actually with Arena of Glory's exert ability ({R}, {T}, Exert: Add {R}{R}), I could pay R from Mountain, then exert Arena for RR, giving me RRR total — enough for Detective's Phoenix (2R)! And the creature would gain haste! That's a strong line! Play Arena of Glory, tap Mountain for R, exert Arena of Glory for RR (paying R from Mountain as the activation cost... wait, that uses the Mountain mana to activate Arena, giving me RR from Arena). So I'd have RR from Arena. That's enough for Detective's Phoenix at {2}{R} — exactly 3 mana (RR + the R I used to activate... no wait). Let me re-read Arena of Glory: "{R}, {T}, Exert {this}: Add {R}{R}." So the cost is {R} + tap + exert. I need to pay R first to activate it, then it produces RR. So: - Tap Mountain for R - Use that R to pay for Arena's exert ability, tapping and exerting Arena → produces RR - I now have RR floating - Detective's Phoenix costs {2}{R} = 3 mana, but I only have RR (2 mana) Not enough. So I can't cast Phoenix this turn. Let me just play Arena of Glory and pass, holding up mana for... well, I don't have instants. Actually, should I play Scalding Tarn instead and save Arena for turn 3 when I can exert it? With Scalding Tarn, I could fetch a Mountain, giving me 2 Mountains for turn 3 (Mountain + fetched Mountain + Arena of Glory = enough for Phoenix with exert). Hmm, but if I play Arena now, next turn I play Scalding Tarn, fetch, and have 3 lands. That also works. The key question is whether I want to attack with Mako this turn and what the opponent has. Let me play **Arena of Glory** now. Next turn with 3 lands I can cast Phoenix normally, or use Arena's exert for extra mana + haste.

Oh wow, Hollow One is showing as castable! We cycled Street Wraith last turn though, not this turn. Wait — the game might be tracking it from the cycling. But we cycled last turn, not this turn... Let me check if it costs {5} minus something. Actually, it's showing in my hand as a new draw (I drew it this turn from the cycling or natural draw). The cost reduction only applies to cards cycled/discarded THIS turn. So it still costs {5}. But the game is showing it as playable with only 2 untapped lands... Actually wait — maybe I can exert Arena of Glory! Mountain ({R}) + Arena exert ({R}, {T}: {R}{R}) = pay R from Mountain to activate Arena, get RR back. That's RR total. Still only 2 mana for a 5-cost spell. Unless the game knows something I don't. Hmm, let me just try to cast it and see what happens. If it's truly castable, the server has verified it.

Interesting, the game is asking how to use Arena of Glory. If I exert it, I get RR + haste for the creature, but I need to pay R to activate the exert ability. With only Mountain + Arena, I'd need Mountain's R to pay for Arena's exert cost, getting RR from Arena — 2 mana total. For Hollow One at {5}, that's not enough... Unless the cycling of Street Wraith from last turn is somehow still counting? Let me just try the exert — a 4/4 with haste on turn 2 would be incredible!
mcp2. {R}, {T}, Exert Arena of Glory: Add {R}{R}. If that mana is spent on a creature spell, it gains haste until end of turn.

Interesting! So what happened is: - Hollow One went to the graveyard (it was cycled, not cast!) — the game auto-cycled it for {2} - Mako got ANOTHER +1/+1 counter (now 3/3 with 2 counters) from the cycling discard trigger - I drew **Lightning Bolt** — a classic! - Graveyard has Street Wraith (creature) and Hollow One (artifact creature) — 2 card types (Artifact, Creature) - Nethergoyf is now a 2/3 - Opponent has Blood Crypt — they're playing Rakdos! Now I have a 3/3 Mako (no longer summoning sick), Lightning Bolt in hand, and both lands tapped. Let me head to combat and attack!

Now I understand what happened: - Opponent played **Thoughtseize** (from Alpha era of disruption, perfected in Lorwyn) — they made me discard Lightning Bolt! That's why Mako got another +1/+1 counter (3 total, now 4/4) and Lightning Bolt is in the graveyard - Opponent went to 13 (paid 2 life for Thoughtseize from 15) - Arena of Glory didn't untap (it was exerted) - I drew a THIRD Detective's Phoenix! - Graveyard now has: Street Wraith (creature), Hollow One (artifact creature), Lightning Bolt (instant) — 3 card types, making Nethergoyf a 3/4! My board: 4/4 Mako (untapped), Arena of Glory (tapped/exerted), Mountain (untapped). Only 1 untapped land (Mountain) giving me R. Opponent has only Blood Crypt (tapped) and Thoughtseize in graveyard. Empty board otherwise. Let me attack with the 4/4 Mako!

4 more damage! Opponent down to 9. Now I'm in postcombat main with: - 0 land drops used this turn (I haven't played a land yet!) - 1 untapped land (Mountain) - Scalding Tarn in hand - 3x Detective's Phoenix all showing as castable! Wait — how can I cast Detective's Phoenix at {2}{R} with only 1-2 untapped lands? Unless... the Bestow cost! Detective's Phoenix has "Bestow—{R}, Collect evidence 6." So for just {R} + exiling 6 mana value of cards from graveyard, I can bestow it on Mako giving +2/+2, flying, and haste! My graveyard: Street Wraith (MV 5), Hollow One (MV 5), Lightning Bolt (MV 1) = 11 total MV. I need to exile at least 6 MV worth. Let me play Scalding Tarn first to maximize my mana options, then bestow a Phoenix on Mako!

Scalding Tarn is on the battlefield now! I should crack it to fetch a Mountain, giving me 3 mana sources. But wait — I should bestow a Phoenix first with just {R} from Mountain. Actually no, let me think... If I crack Scalding Tarn and fetch a Mountain, I'll have Mountain + fetched Mountain = 2 untapped lands (Arena still tapped). With 2R, I could cast a Phoenix normally for {2}{R}! But bestowing for {R} + evidence 6 is cheaper on mana. However, bestowing eats my graveyard which hurts Nethergoyf. Current graveyard types: Artifact, Creature, Instant (3 types) → Nethergoyf is 3/4. If I exile cards for evidence 6, I need to exile at least 6 MV. Exiling Street Wraith (5) + Lightning Bolt (1) = 6 MV exactly. That would leave only Hollow One (Artifact Creature) → 2 types (Artifact, Creature) → Nethergoyf becomes 2/3. Not great. Alternative: Crack Scalding Tarn to get a Mountain (going to 17 life), then hard cast Detective's Phoenix for {2}{R} using Mountain + Mountain + (need 1 more... I only have 2 untapped Mountains). That's only 2R, Phoenix costs 2R (which is exactly {2}{R} = 3 mana, and RR counts as 2, so I need 1 more generic). Hmm, I only have 2 untapped lands after fetching. {2}{R} needs 3 mana. I can't hard cast it. So the best play is to bestow for {R} and collect evidence 6. A 6/6 flying Mako is devastating. Let me exile Street Wraith (5 MV) + Lightning Bolt (1 MV) = 6 to preserve Hollow One's types. Let me cast a Detective's Phoenix using bestow!

Hmm, it won't accept answer=true. The only choice is Hollow One or answer=false. Let me try selecting Hollow One — maybe I have to select it and then it'll confirm. Actually wait — the issue might be that with exactly 6 MV selected, I need to somehow finalize. Let me try selecting nothing or pass. Since answer=false means "cancel targeting" and I don't want to cancel, let me try selecting Hollow One (it would give me 11 MV, more than 6). Actually, re-reading: "selected 2, min 1, selected mana value 6 of 6" — the 6 of 6 means I've met the requirement. In previous similar interactions, maybe I need to try a different approach. Let me try answer=false — perhaps it confirms when the minimum is met rather than cancelling.

I should crack Scalding Tarn at end of turn to thin my deck and get a land into play untapped for next turn. That's a classic fetchland play — always crack at the last possible moment for maximum information.

Excellent! Let me assess the situation: **My board:** 6/6 Mako (with Phoenix bestowed), Mountain, Arena of Glory, Blood Crypt (3 untapped lands = RRB) **My hand:** 2x Detective's Phoenix, Nethergoyf (3/4), Thoughtseize **My graveyard:** Hollow One, Scalding Tarn (Artifact, Creature, Land = 3 types → Nethergoyf is 3/4) **Opponent's board:** Blood Crypt (tapped), Undercity Sewers (tapped), Nethergoyf 3/4 (summoning sick) **Opponent's hand:** 6 cards! Opponent has their own Nethergoyf as a blocker. **Opponent's graveyard:** Thoughtseize, Street Wraith, Mishra's Bauble (Sorcery, Creature, Artifact = 3 types → their Nethergoyf is also 3/4) Strategy: - I should Thoughtseize first to see their hand and strip their best card. This costs B and 2 life (going to 13). - Then I can cast Nethergoyf for B (but I'd need another B source). - Or cast a Detective's Phoenix for 2R. Wait, with 3 lands (Mountain, Arena of Glory, Blood Crypt), I have access to RRB. Thoughtseize costs B, Phoenix costs 2R. If I Thoughtseize with Blood Crypt, I have RR left for... can't cast Phoenix (needs 2R = 3 mana). If I Thoughtseize (B from Blood Crypt), then cast Nethergoyf (B from... I only have Mountain and Arena of Glory left, which produce R). So I can't cast both Thoughtseize and Nethergoyf. Actually, Arena of Glory can produce any color if I exert it! Let me check.

Arena only makes R. So my mana is: Mountain (R), Arena of Glory (R or RR if exerted with R), Blood Crypt (B or R). Best plan: 1. Thoughtseize (B from Blood Crypt) - see their hand, strip best card. Goes to 13 life. 2. Then exert Arena of Glory (tap Mountain for R, use to pay exert cost, get RR) - that gives me RRR total... wait no. Exert costs R + T. So I tap Mountain for R, then exert Arena paying R and tapping it to get RR. So net: I spent Mountain (tapped) + Arena (tapped, exerted) and have RR floating. Plus Blood Crypt already tapped for B. Actually: After Thoughtseize, Blood Crypt is tapped. I have Mountain and Arena untapped. - Tap Mountain → R - Exert Arena (costs R+T) → spend that R, get RR - Total: RR floating, but I need 2R (which is 3 total mana) for Phoenix. I only have RR. Not enough. So after Thoughtseize, I can only cast Nethergoyf if I have a B source. I don't. I can't cast Phoenix (not enough mana). Alternative: Don't Thoughtseize. Cast Detective's Phoenix for 2R: - Mountain (R) + exert Arena (costs R... but I don't have the R to activate). Hmm, let me think again. To exert Arena: I need to pay R as an activation cost, plus tap Arena. It produces RR. So: Tap Blood Crypt for R. Use that R to exert Arena → get RR. Now I have RR floating + Mountain untapped → tap Mountain for R → RRR total. That's exactly {2}{R} for Phoenix! But then I can't Thoughtseize (no B left). Which is better: Thoughtseize or Phoenix? Opponent is at 9 life. My 6/6 Mako attacks. If they don't block, 6 damage puts them to 3. A Phoenix would add 2 more flying damage if I attack with both (8 total). But their Nethergoyf 3/4 can block. Actually, if I cast Phoenix (2/2 flying haste), I attack with 6/6 Mako AND 2/2 flying Phoenix. They have to block Mako with Nethergoyf (3/4 blocks 6/6, Nethergoyf dies, Mako survives at 6/2). The 2/2 flying gets through for 2. Opponent goes to 7. Or if I Thoughtseize, I strip their best card, attack with just 6/6 Mako. If they block with Nethergoyf, Mako kills it and survives. If they don't block, they go to 3. Hmm, Thoughtseize gives me info AND strips a card. They have 6 cards and I'm worried about removal. If they have Fatal Push or something, my 6/6 Mako could die. I think Thoughtseize first is the right call. Strip their best answer, then attack with Mako confidently.

For Thoughtseize I just need B. I should use Blood Crypt for B and not use Arena at all. Let me pick the basic tap for R since I don't want to exert Arena unnecessarily. Wait — why is Arena being asked about? Thoughtseize costs {B}. Let me just tap for R simply. Actually, I think auto-tapper picked Arena. Let me just use the basic R ability to preserve the exert option for later.

Hmm, I have 2R in pool but Thoughtseize needs B. Something went wrong with mana payment. Let me pass priority to let it resolve... actually the auto-tapper must have already handled it. Wait no, 2R can't pay for B. Let me just pass and see if it resolves correctly.

Thoughtseize resolved! Now I can see their hand has: Stubborn Denial, Counterspell, Psychic Frog (and presumably 3 more that are lands). This is crucial info! They have TWO counterspells! Counterspell is the big one — it's a hard counter. Stubborn Denial is conditional (only a 1-mana Negate if they have a 4+ power creature, which their Nethergoyf is only 3/4... so it's just a Force Spike equivalent right now). I should take **Counterspell** — it's the unconditional hard counter. Stubborn Denial is weaker especially since their Nethergoyf is only 3/4 (no ferocious). Psychic Frog is a threat but I'd rather strip the countermagic since I have a commanding board position.

I have 2R floating and can cast Detective's Phoenix (costs 2R = 3 mana). Wait, I have 2R floating but the Phoenix costs {2}{R} which is 3 mana total. I only have 2R. I'd need one more mana from my remaining untapped land (Blood Crypt). Actually wait — Arena and Mountain are tapped from Thoughtseize. Blood Crypt should still be untapped (the game used Arena for the R and presumably Blood Crypt for B). Let me check: I have 2R floating so maybe Blood Crypt produced R too? Let me see... The game shows 2R in pool and lists Phoenix as castable. If I have 2R in pool + Blood Crypt untapped, I can tap Blood Crypt for R to get 3R total = {2}{R} for Phoenix. Phoenix with haste means I can attack with 6/6 Mako AND 2/2 flying! Opponent at 9 life. Their Nethergoyf 3/4 can block Mako but the Phoenix flies over. If they block Mako: Mako (6/6) kills Nethergoyf (3/4), Mako survives at 6/2. Phoenix hits for 2, opponent to 7. If they don't block: 6+2 = 8 damage, opponent goes to 1! They only have Stubborn Denial as interaction and no ferocious, so it's just a Force Spike. I should cast Phoenix — they'd need to pay U+1 extra to Stubborn Denial it, but they have no untapped lands! Cast Phoenix!

Wait — it's asking me to select a creature. This must be the bestow targeting. But I selected the regular cast, not bestow. Hmm, the "collect evidence 6" is the additional cost for the regular cast too! And it's showing creature targets... Actually, looking at this more carefully — maybe since both modes require collecting evidence 6, it's asking about bestow. I want to cast it as a creature (2/2 flying haste), NOT as an aura. Let me cancel and see if there's a different option.

Hmm, it only shows {2}{R} cast options. When I select one, it asks to target a creature which means bestow. But the cost shown is {2}{R} not {R}. Wait — actually the card text says: "As an additional cost to cast this spell, collect evidence 6." That's for the normal cast! And bestow costs {R} + collect evidence 6. Both modes collect evidence. So the {2}{R} IS the normal cast. But it's asking to target a creature... maybe it's offering the option to bestow it onto a creature. The "required=false" means I can decline targeting and cast it as a creature. Let me try again and not select a target.

Interesting — opponent's Nethergoyf is now 4/5! They must have gotten another card type in graveyard (Counterspell = instant → now 4 types). This means Stubborn Denial now has ferocious (4+ power)! This target selection is for bestow. I want it as a creature, not an aura. But wait — bestowing onto my 6/6 Mako would make it 8/8 with flying and haste. That's devastating! If I bestow onto Mako, I swing with an 8/8 flyer. They take 8 and go to 1! They can't block a flyer with Nethergoyf. But wait, if they have Stubborn Denial with ferocious (Nethergoyf is 4/5), they can counter my Phoenix for just U. Do they have U available? Their lands are all tapped! So even with ferocious, they can't cast Stubborn Denial! Bestow on Mako is the play! 8/8 flying haste, they can't block it, they go to 1. Actually wait — Mako already doesn't have summoning sickness (it attacked before). So an 8/8 flying Mako hits for 8, opponent at 9 → 1 life. Then next turn I win. But actually, if I just cast Phoenix as a creature, I get a 2/2 flying haste + 6/6 Mako. If they block Mako with Nethergoyf, I still hit for 2 flying (they go to 7). If they don't block, 8 total (they go to 1). If I bestow on Mako, I have one 8/8 flyer. They can't block it (no flyers/reach). 8 damage, they go to 1. But if Mako dies, I lose both the aura AND the creature (well, bestow means Phoenix becomes a creature if Mako dies, but still). Bestow is better here — guaranteed 8 damage since they can't block a flyer! As a creature, they could block the Mako with Nethergoyf and I'd only deal 2. Let me bestow on Mako!

Opponent is at 1 life! I'm at 9 (they must have hit me too). It's Turn 5 and I'm in precombat main. I have an 8/8 flying Mako. Opponent at 1 life — any attack kills them! But wait, I should make sure my attack connects. Let me check the board state. They might have blockers or tricks. At 1 life, I just need to swing with Mako. Actually, I should play Scalding Tarn first (land drop), then consider if I need to cast anything pre-combat. Nethergoyf could be another attacker as insurance. Let me play the land first.

Arena is being tapped for mana. Nethergoyf costs {B}, so I need black mana, not red. But the autotapper picked Arena. I should just tap for R (the simple option) since I can't use red for Nethergoyf anyway. Actually, Blood Crypt should produce B... The autotapper is confused. Wait — maybe it's asking which ability to use on Arena but another land is actually providing the B. Let me just tap for R since I don't need the exert ability.

Ohmygerd BESTIE they're attacking with an 8/8 FLYING SHARK?! 🦈😱 That's like, SUCH a vibe kill! I'm literally at 1 life and have NO creatures to block flyers! This is giving 'about to lose real bad' energy... Wait, they're at 9 life and I'm at 1... I need a MIRACLE here! Let me cast this Tarfire anyway - not that it'll save me from the shark, but maybe I can take out something else? 😭✨

They're Tarfiring my Nethergoyf — that doesn't matter, Mako is still unblocked and flying for 8. They're at 1 life. Just pass priority and let combat damage happen.
