Overview:

This Simic (GU) deck helmed by Koma, World-Eater focuses on explosive token generation and creature-based value, leveraging Koma's ability to create four 3/3 Serpents whenever it deals combat damage. The strategy combines ramp, cloning effects (Sakashima of a Thousand Faces, Helm of the Host), and token doublers (Doubling Season, Adrix and Nev, Twincasters) to flood the board with massive threats. Secondary win conditions include Craterhoof Behemoth alpha strikes, Unnatural Growth combat multipliers, and stax-like control via Junk Winder and Grappling Kraken. Koma serves as both a resilient threat (ward 4) and a token engine, enabling snowballing board states.

Primer:

Core Strategy Execution:

1. Early Ramp (Turns 1-4): Deploy mana dorks (Llanowar Elves, Birds of Paradise), land-based ramp (Cultivate, Three Visits), and rocks (Sol Ring, Arcane Signet) to reach 6+ mana.
2. Deploy Koma (Turns 5-6): Cast Koma with protection (Lightning Greaves, Heroic Intervention). Prioritize cloning effects (Spark Double, Irenicus's Vile Duplication) to create multiple Komas.
3. Token Overload (Turns 6+): Attack with Koma(s) to generate 4+ Serpent tokens per hit. Amplify with Doubling Season (8 tokens per hit) or Second Harvest. Use Spawning Kraken to convert tokens into 9/9 Krakens.
4. Win Conditions:
   • Combat: Overrun with Craterhoof Behemoth, Unnatural Growth, or Return of the Wildspeaker.
   • Stax Lock: Junk Winder + token generators to tap down opponents' boards.
   • Exponential Clones: Helm of the Host on Koma creates non-legendary copies that each generate 4+ tokens on attack.

Mulligan Priorities:

• Keep hands with 3+ lands and at least two ramp pieces.
• Prioritize early clones (Sakashima of a Thousand Faces, Double Major) if Koma is already in hand.
• Avoid hands lacking ramp or with only high-CMC payoffs.

Key Tips:

• Use Whelming Wave as a one-sided board wipe (spares Serpents/Krakens).
• Hullbreaker Horror disrupts opponents while protecting your board via bounce.
• Aesi, Tyrant of Gyre Strait and Tatyova, Benthic Druid turn land drops into card advantage.
• Clone Spawning Kraken or Junk Winder for exponential value.

Weaknesses:

Critical

• Koma Dependency: Removing Koma repeatedly (despite ward 4) cripples the primary engine.
• Board Wipes: Farewell or Cyclonic Rift resets the token army with limited recovery tools.
• Anti-Token Tech: Cursed Totem/Torpor Orb disable Koma's token generation and key ETBs.

Moderate

• Slow Setup: Minimal fast mana beyond Sol Ring delays Koma’s T5-6 deployment.
• Limited Interaction: Few answers to resolved enchantments/artifacts (only Nature's Claim, Reclamation Sage).

Minor

• Flyer Vulnerability: Relies on Serpent of Yawning Depths to block flyers.
• Graveyard Reliance: Recursion (Eternal Witness) is minimal but present.

Most Important Cards:

• Koma, World-Eater (Primary token engine/wincon)
• Doubling Season (Doubles tokens and +1/+1 counters)
• Craterhoof Behemoth (Combat finisher)
• Helm of the Host (Exponential Koma cloning)
• Adrix and Nev, Twincasters (Token doubler)
• Junk Winder (Stax lock enabler)
• Unnatural Growth (Combat multiplier)
• Hullbreaker Horror (Disruption/protection)
• Spawning Kraken (Secondary token generator)
• Finale of Devastation (Tutor + finisher)

Attribute Ratings:

Speed: 6/10

• Can threaten wins via Craterhoof or token swarm by T7-8, but lacks fast mana for earlier explosive turns.

Resilience: 5/10

• Koma’s ward 4 and protection spells help, but token strategies fold to repeated wipes. Limited recursion.

Consistency: 7/10

• Strong ramp and card draw (12+ sources), but key doublers/clones are singleton and lack tutors.

Interaction: 5/10

• 8 targeted removal/counters, but minimal stack interaction and no board wipes beyond Aetherize.

Rating Justification:

This deck has a clear T7-8 win potential through combat or token synergies but lacks the speed and redundancy of higher-tier decks. While resilient to single-target removal, it struggles against dedicated control or stax. Its power sits between Focused and Optimized Casual tiers.

Power level: 6.0 - 6.5
