Overview:

This Koma, World-Eater deck focuses on ramping into its commander to generate massive Serpent tokens while amplifying their impact through +1/+1 counters and combat synergies. The strategy leverages high-value permanents like Primal Vigor and Court of Garenbrig to scale threats, with secondary win conditions in overrun effects like Preposterous Proportions and Genesis Wave. While moderately resilient to single-target removal thanks to ward 4 and equipment protection, the deck lacks redundancy for its core engine and struggles against focused disruption.

Primer:

Core Strategy:

1. Ramp Phase: Utilize 1-2 CMC mana dorks (Birds of Paradise, Llanowar Elves) and enchantment-based acceleration (Wild Growth) to cast Koma by turns 4-5.
2. Token Generation: Attack with Koma to create four 3/3 Serpent tokens per combat, amplified by Primal Vigor to make eight tokens.
3. Value Scaling: Use +1/+1 counter doublers (Court of Garenbrig) and anthem effects (Heraldic Banner) to turn tokens into lethal threats.
4. Finishers: Overwhelm opponents through token swarms or Finale of Devastation-powered alpha strikes.

Key Interactions:

• Coastal Piracy draws cards for each token dealing combat damage
• Garruk's Uprising provides trample and card draw for 4+ power creatures
• Sword of Feast and Famine enables mana untap for post-combat plays

Mulligan Priorities:

• Keep hands with 3 lands and 2+ ramp sources
• Prioritize Swiftfoot Boots or Sword of Feast and Famine for protection
• Avoid slow starts without turn 2 ramp

Weaknesses:

Critical:

• Relies entirely on Koma for token generation (no backup engines)
• Limited answers to board wipes beyond Aetherize
  Moderate:
• Weak to Cursed Totem-style effects disabling mana dorks
• No graveyard recursion for key pieces
  Minor:
• Susceptible to land destruction due to enchantment-based ramp

Most Important Cards:

• Primal Vigor
• Finale of Devastation
• Unnatural Growth
• Garruk's Uprising
• Swiftfoot Boots
• Court of Garenbrig
• Sword of Feast and Famine
• Genesis Wave
• Tatyova, Benthic Druid
• Coastal Piracy

Attribute Ratings:

Speed: 6/10
Can deploy Koma by turn 5 consistently, with explosive turns 7-8 via token doubling. Lacks fast mana for earlier threats.

Resilience: 5/10
Ward 4 and equipment-based protection help against single-target removal, but folds to 3+ commander removals. Limited recursion.

Consistency: 5/10
Only Finale of Devastation as a tutor. Relies on card draw engines that require board presence.

Interaction: 4/10
Moderate counterspell suite (Disdainful Stroke, An Offer You Can't Refuse) but lacks free interaction. Removal is situational.

Rating Justification:

This deck sits between "Optimized Casual" (5.0) and "High-Power Casual" (5.5) on the rubric. It can consistently threaten wins via combat around turns 8-10 but lacks:
1) The tutor density of 6.0+ decks
2) The stax/resilience packages of true competitive builds
3) Infinite combos for faster closes

While stronger than precons due to focused ramp and scaling, it can't reliably compete with T7-8 combo decks.

Power level: 5.0 - 5.5
