I'll choose to go first - being on the play gives a tempo advantage that's crucial for winning.

Good, I'm on the play. Now let's see the mulligan decision.
thinkingOpus Grudge
Let me evaluate this hand: - 3x Arid Mesa, Godless Shrine, Mountain = 5 lands (a bit land-heavy) - Scion of Draco - needs domain to be cheap; with Mountain (R), Godless Shrine (W/B), and fetches finding Plains, I could get 3-4 basic land types, making it cost 6-8 mana still. That's slow. - Teferi, Time Raveler - excellent card but needs {1}{W}{U} and I don't see a blue source yet (would need to fetch one) The hand has too many lands (5 out of 7), the Scion is likely too expensive early, and Teferi needs blue which I'd need to fetch. But 3 fetches give great fixing, Teferi is a powerful play, and we can find blue with the fetches. This is keepable - it's not amazing but mulling to 6 on the play is risky.

I'll check my opening hand to make the mulligan decision.

Turn 1. I'll play an Arid Mesa - I don't need mana this turn since I can't cast anything for 1 mana. I'll crack it later when I need the mana or to thin my deck.

Wait, it shows land_drops_used=0 still - the Mesa went to the battlefield but I still have a land drop? Let me check - no, the Mesa IS my land play. I shouldn't crack it yet since I don't need mana this turn. I'll pass and save it to crack on opponent's end step or when I need it.

Opponent played Windswept Heath, cracked it for Overgrown Tomb (paid 1 life for fetch, 2 life for shock land = 19 life). They're in black/green territory. It's their main phase - I don't need to crack my Mesa yet. Let me pass.

OK, it's my turn 2 now, I drew Territorial Kavu. I'm in declare attackers but I have no creatures. I need to plan my turn - I want to play a land and cast Territorial Kavu (costs RG). Wait, I'm already in combat. I missed my main phase. Let me pass through combat and play in postcombat main.

I need to plan carefully. I want to cast Territorial Kavu (RG). I have Arid Mesa on the battlefield and need to play a second land. Plan: Play Mountain from hand (for R), then crack Arid Mesa to search for a Stomping Ground or similar for G. Wait - Arid Mesa can only find Mountain or Plains. I can't get green from it. Alternative: I could play the second Arid Mesa as my land drop. Then crack the first Mesa for a Mountain (R) and crack the second for... also just Mountain or Plains. No green source from Arid Mesa. I can't cast Territorial Kavu this turn without a green source. Arid Mesa only finds Mountain or Plains. For Teferi (1WU), I need a blue source too. Let me think about what my deck likely has - this looks like a Domain/Zoo deck. I probably have Hallowed Fountain (Plains/Island), Steam Vents (Island/Mountain), Sacred Foundry (Mountain/Plains), etc. Best plan for turn 2: Play Mountain as my land drop. Crack Arid Mesa to find a Stomping Ground (wait, that's Mountain/Forest - yes! Arid Mesa can find it since it's a Mountain). That gives me R from Mountain and G from Stomping Ground = RG for Territorial Kavu! Let me play Mountain first.

I see the search options. I need green for Territorial Kavu (RG). Let me check what's available: - Indatha Triome (WBG type land) - Plains - Steam Vents (UR) - Steam Vents (UR) - Temple Garden (WG) - Thundering Falls (?) I want to get Temple Garden - it gives me both W and G. With Mountain (R) + Temple Garden (G), I can cast Territorial Kavu, and the domain count would be Mountain (Mountain type), Temple Garden (Forest + Plains types) = 3 basic land types, making Kavu a 3/3. That's great! Let me also think about Teferi next turn - I'd need U. I have Godless Shrine in hand (W/B), so next turn I could play that and then with another fetch find a blue source. Temple Garden is the pick - it maximizes domain AND gives me the green for Kavu.

Territorial Kavu is a 3/3 now with 3 basic land types (Plains, Mountain, Forest from Temple Garden + Mountain). Let's cast it!

It's turn 3 now. My Kavu resolved and is a 3/3 not summoning sick. Opponent played a Dryad Arbor and Forest. I drew another Territorial Kavu! Let me think about the plan: - I have Godless Shrine in hand (W/B). If I play it, I get 4 basic land types (Plains, Mountain, Forest, Swamp) making Kavu a 4/4! - I can also cast the second Territorial Kavu for RG. - I need to think about Teferi (1WU) - I still need blue. If I play Godless Shrine now and attack, next turn I can fetch for a blue source. Best play: Play Godless Shrine (pay 2 life for untapped, going to 15), cast second Territorial Kavu. Both become 4/4s. Attack with the first Kavu. Wait, let me think about sequencing. If I play Godless Shrine untapped: - Lands: Mountain (R), Temple Garden (G/W), Godless Shrine (W/B) = 3 lands, 4 basic types - I need RG for second Kavu: Mountain for R, Temple Garden for G - That works! Both Kavus become 4/4. But should I save life? I'm at 17. Playing Godless Shrine untapped costs 2 life β†’ 15. Is it worth it to deploy two 4/4 threats? Absolutely. Let me play Godless Shrine first.

Second Kavu resolved but is summoning sick, so only the first one (p12) can attack. Opponent has Dryad Arbor (1/1, also summoning sick) that can't block. Let me attack with the first Kavu as a 4/4 - they might block with Dryad Arbor but it's summoning sick so it can't. 4 damage to face!

I have: - Arid Mesa x2 (fetchlands, useful but I have 2) - Scion of Draco (costs 12 but discounted by 2 per basic type - with 4 types that's 4 mana, still expensive but powerful) - Teferi, Time Raveler (very strong, need blue mana though) I should discard an Arid Mesa - I have two, I only need one more land drop, and I want to keep both Scion and Teferi.

Excellent! Turn 4, opponent is at 13 life (my Kavu connected for 4, plus their fetches/shocks). I drew Phlage, Titan of Fire's Fury and Consign to Memory! Phlage is amazing here - when it enters, it deals 3 damage to any target and gains 3 life, but then I have to sacrifice it (unless escaped). That's still a free 3 damage + 3 life, and it goes to graveyard to potentially escape later. Let me also look at opponent's board - they have Dredger's Insight (an enchantment), Young Wolf (1/1 with undying), Dryad Arbor, and lands. Plan: Play Arid Mesa as land drop, cast Phlage (1RW) dealing 3 to opponent's face. Then attack with both 4/4 Kavus. That's 3 + 8 = 11 damage if unblocked, putting them from 13 to 2! They have Young Wolf (1/1) and Dryad Arbor (1/1) to block, so they could block one Kavu and take 4 + 3 = 7, going to 6. Actually wait - Phlage enters and I must sacrifice it. So it won't be around as an attacker. But the ETB 3 damage is great. Let me play the Arid Mesa first, then cast Phlage.

Phlage entered! Two triggered abilities - one is the ETB damage/lifegain, the other is the sacrifice trigger. I need to order them. I want the damage trigger to resolve first (or last on stack). Since the last ability put on the stack resolves first, I should put the sacrifice trigger on the stack first, then the damage trigger second. That way the damage trigger resolves first (dealing 3 and gaining 3), then the sacrifice trigger resolves. Actually, the order matters for which one I want on the stack first. Let me think... stack is LIFO. I want the damage to resolve before the sacrifice. So I should put sacrifice on the stack first (bottom), then damage on top. The damage resolves first, then sacrifice. Let me check which is which by looking at p34 and p35.

They're ability objects, not cards. The order doesn't actually matter here since both triggers will resolve regardless - the sacrifice doesn't counter the damage. Both will go on the stack and resolve. Let me just pick the first one.

Phlage's ETB deals 3 damage to any target. Should I hit the opponent's face or a creature? - Opponent at 13 life. If I hit face: 13 β†’ 10. Then attack with two 4/4 Kavus. They have Young Wolf (1/1, summoning sick - can't block!) and Dryad Arbor (1/1, tapped - can't block!). Both unblockable! That's 8 damage, opponent goes to 2! - I gain 3 life: 15 β†’ 18. Face it is! Maximum pressure - they'll be at 2 with no blockers available.

Phlage dealt 3 to face (opponent at 10), I gained 3 (at 18), and Phlage was sacrificed (now in graveyard for future escape). Both Kavus are ready to attack. Opponent has Young Wolf (summoning sick, can't block) and Dryad Arbor (tapped, can't block). All-out attack for 8 damage!

Both Kavus attacking! Two attack triggers on the stack. I have the option to crack Arid Mesa now but I'll hold it. Let me pass priority to resolve the triggers - I'll use the Kavu triggers to exile cards from opponent's graveyard (to deny any graveyard synergy, especially with Dredger's Insight).

It chose the discard mode for the first Kavu trigger. I need to discard a card. I should keep Teferi and Scion of Draco (both powerful). Consign to Memory is a narrow counter (only triggered abilities or colorless spells). I'll discard Consign to Memory - it's the least impactful. Wait - actually Scion of Draco costs 12 minus 8 (4 basic types Γ— 2) = 4 mana. That's still a lot. But it gives all my creatures amazing abilities. And Teferi is just great. I'll discard Consign to Memory.

I drew **Leyline of the Guildpact**! That's incredible - it makes all my lands every basic type (5 domain!) and all my nonland permanents all colors. With 5 basic land types, my Kavus become 5/5! And Scion of Draco would cost only 2 mana (12 - 10)! And with Scion, my creatures would get ALL abilities (vigilance, hexproof, lifelink, first strike, trample) since they'd be all colors! But first, there's still the second Kavu trigger on the stack. I need to resolve that. Let me pass priority to handle it. I'll choose exile mode for the second trigger to exile a card from opponent's graveyard.

The second Kavu trigger also chose the discard mode. I need to discard again. I have Leyline of the Guildpact, Scion of Draco, and Teferi. Let me think carefully: - **Leyline of the Guildpact** costs {G/W}{G/U}{B/G}{R/G} = 4 mana, all hybrid with green. I can pay it with 4 green sources, or a mix. With my current lands (Mountain, Temple Garden, Godless Shrine, Arid Mesa), I could pay GWGW from my lands... actually I don't have enough green right now. Let me check: I need 4 mana, each with a G option. Temple Garden gives G, Arid Mesa can fetch... I'd need to crack the Mesa for a land. - **Scion of Draco** with Leyline out would cost 12 - 10 (5 types Γ— 2) = 2 mana. That's incredible. - **Teferi** needs {1}{W}{U} - I need a blue source. I should keep Leyline of the Guildpact - it combos perfectly with Scion and makes Kavus 5/5. Teferi needs blue mana I don't have. I'll discard Teferi and draw. Actually wait - next turn I could crack Arid Mesa to find an Island or blue source... but Arid Mesa only finds Mountain or Plains. So I can't easily get blue for Teferi anyway. Discard Teferi.

OPPONENT IS AT 2 LIFE! Both Kavus got through for 8 damage! 10 β†’ 2! And I drew **Ragavan, Nimble Pilferer**! I'm at end of turn. I should crack Arid Mesa now to thin the deck and get a land untapped for next turn. Actually, I should think about what I need: - Next turn I have Leyline of the Guildpact ({G/W}{G/U}{B/G}{R/G}) - I can pay all 4 pips with green mana. - Scion of Draco would cost 12 - 10 = 2 with Leyline (5 basic types). - Ragavan costs {R}. - Opponent is at 2 life - any attack kills them! I should crack the Mesa at end of turn to get a land untapped. I'll fetch a Hallowed Fountain or Steam Vents if I have one for the Island type, or just another Mountain for Ragavan's red. Wait - actually with Leyline, all my lands become every basic type. So I already get 5 domain with Leyline out. I just need green sources to cast Leyline. Let me think: next turn my 4 lands untap. Mountain (R), Temple Garden (G/W), Godless Shrine (W/B), plus whatever I fetch. For Leyline I need {G/W}{G/U}{B/G}{R/G}. I can pay: Temple Garden for G (covers G/W pip), Mountain for R (covers R/G pip), Godless Shrine for B (covers B/G pip). For the {G/U} pip I need U or G. I'd need another green source. If I fetch a Forest... wait Arid Mesa finds Mountain or Plains. I can't get a Forest. Hmm. I could fetch a Stomping Ground (Mountain + Forest, so it counts for Arid Mesa as Mountain). That gives me R or G. Then I'd have: Temple Garden (G), fetched land (G), Godless Shrine (B), Mountain (R). That covers all 4 Leyline pips! But honestly, with opponent at 2 life, I just need to attack with either Kavu next turn. They can only block with Young Wolf (1/1) and Dryad Arbor (1/1). Even if they block one Kavu, the other hits for 4 and kills them. Let me crack Mesa at end step to have maximum mana next turn.

I can fetch: Indatha Triome, Plains, Steam Vents (x2), or Thundering Falls. Let me think about what I need. Opponent is at 2 life. Next turn I just need to attack with Kavus. But they might have removal or a blocker. Let me plan for Leyline of the Guildpact cast. For Leyline ({G/W}{G/U}{B/G}{R/G}), I need: - Pip 1: G or W - Pip 2: G or U - Pip 3: B or G - Pip 4: R or G Current lands: Mountain (R), Temple Garden (G or W), Godless Shrine (W or B). If I fetch **Steam Vents** (U/R): Mountain (R for pip 4), Temple Garden (G for pip 1), Godless Shrine (B for pip 3), Steam Vents (U for pip 2). PERFECT! All 4 pips covered! And Steam Vents adds Island type = 5 basic land types! Kavus become 5/5! Plus I'd have blue for potential future draws. I'll pay 2 life to have it enter untapped (I'm at 17, so 17-1 fetch -2 shock = 14, totally fine).

It's end of turn, all my lands are tapped anyway. I don't need the mana right now - let it enter tapped to save 2 life. It'll untap next turn.

Turn 5! My Kavus are now 5/5 with the Island type from Steam Vents! Opponent is at 4 life (gained 2 from Dredger's Insight triggers). They added Badgermole Cub, a second Young Wolf, a second Dredger's Insight, and animated a Forest as a 1/1 creature. Their board has blockers: Young Wolf (1/1, not sick), Forest creature (1/1, tapped), Dryad Arbor (1/1, tapped), Badgermole Cub (2/2, summoning sick), Young Wolf #2 (1/1, summoning sick). So only one Young Wolf can block (the non-sick one, p28). It blocks one 5/5 Kavu. But 4 damage still gets through from the other Kavu = they're dead! Wait, I drew a second Leyline of the Guildpact! And I can also cast Scion of Draco for just 2 mana (12 - 10 = 2). Optimal plan: Just attack with both 5/5 Kavus. They can only block one with Young Wolf (1/1). The other 5/5 gets through = they take 5, going from 4 to -1. Dead! But wait, should I play Ragavan first? No need - Kavus alone win the game. Let me just go to combat. Actually, let me think if Scion of Draco would help. For 2 mana it gives all my creatures first strike + trample + vigilance + hexproof + lifelink. That's amazing if the opponent tries tricks, but I win this turn regardless. The trample means even if they block, damage tramples over. Let me play Scion of Draco for 2 mana first (gives trample, so even blocking is futile), then attack.

PERFECT! Scion of Draco resolved! My Kavus are now 5/5 with **First Strike** and **Trample**! Plus vigilance, hexproof, and lifelink from the other color keywords! Opponent is at 4 life with: - Young Wolf (1/1, can block) - Badgermole Cub (2/2, summoning sick - can't block) - Young Wolf #2 (1/1, summoning sick - can't block) - Dryad Arbor, Forest creature (both tapped - can't block) Only one Young Wolf can block. With trample on my 5/5 Kavus: - If they block one 5/5 with Young Wolf, it deals 4 trample damage. The other hits for 5. That's 9 damage total. They're at 4 = DEAD. - Even better, first strike kills the Young Wolf before regular damage, so all 5 tramples over! Time to end this.

The opponent blocked! Both Young Wolves blocking Kavu #1 (p12), and Badgermole Cub (2/2) blocking Kavu #2 (p20). And I drew **Leyline Binding** - incredible! Now I need to assign first strike damage for Kavu #1 (5/5 first strike, trample) vs two Young Wolves (each 1/1). With trample, I need to assign at least lethal to each blocker, then the rest tramples over. - Young Wolf #1: assign 1 damage (lethal) - Young Wolf #2: assign 1 damage (lethal) - That leaves 3 damage to trample over to opponent! Opponent at 4. Kavu #1 tramples 3. Kavu #2 (5/5 first strike) vs Badgermole Cub (2/2) - assign 2 to Cub, 3 tramples over. That's 3 + 3 = 6 trample damage. Opponent goes from 4 to -2. DEAD! Wait, this is first strike damage step. Both Kavus have first strike. Let me assign the damage optimally:

Opponent is at 1 life! The first Kavu trampled 3 over the Wolves (4 β†’ 1), plus lifelink gained me life. Now Kavu #2 vs Badgermole Cub (2/2). Assign 2 to Cub (lethal), and 3 tramples over = that's 3 damage to an opponent at 1 life. GG!
