Overview:

This Tymna/Thrasios deck is a high-octane cEDH build focused on assembling fast, protected combos through hyper-efficient tutors and free interaction. Utilizing multiple infinite mana lines (Kinnan/Basalt Monolith, Devoted Druid/Swift Reconfiguration) that feed into Thrasios' draw-engine and Thassa's Oracle wincons, the deck operates at peak cEDH velocity. With 14 tutors, 8 free counterspells, and premium fast mana, it consistently threatens T2-3 wins while maintaining robust interaction.

Primer:

Core Strategy: The deck combines turbo Naus lines with creature-based infinite mana combos, leveraging its 4-color access to create multiple protected win paths:

1. Fast Mana Engine: Open with Moxen, Chrome Mox, or Rituals to power out early Ad Nauseam/Necropotence for massive card advantage. Survival of the Fittest enables creature combo assembly.
2. Primary Wincons:
   • Thassa's Oracle + Demonic Consultation/Tainted Pact
   • Thrasios + Infinite Mana (Kinnan/Basalt Monolith or Devoted Druid/Swift Reconfiguration)
   • Finale of Devastation X=10 fetching Walking Ballista (implicit via Kinnan activation)
3. Protection Suite: Free counters (Force of Will/Negation, Fierce Guardianship) protect combos. Stax pieces like Drannith Magistrate and Opposition Agent disrupt opponents.

Mulligan Priorities:

• Keep hands with 1-2 mana sources + fast mana/tutor
• Prioritize T1-T2 Ad Nauseam/Necropotence enablers
• Reject hands without early action or color fixing

Key Tips:

• Use Tymna's card draw to refuel after early interaction
• Sequence tutors to find missing combo pieces first
• Hold free counters for opposing win attempts
• Kinnan activates at instant speed - use end step before your turn

Avoid Traps:

• Don't overextend creatures into board wipes
• Reserve Demonic Consultation for guaranteed wins
• Manage life total carefully with Ad Nauseam

Weaknesses:

Critical: None
Moderate:

• Vulnerable to Cursed Totem-effects shutting off creature combos
• Opposition Agent can block key tutors
  Minor:
• Limited planeswalker interaction (relies on bounce/Combat)

Most Important Cards:

• Thassa's Oracle
• Demonic Consultation
• Ad Nauseam
• Survival of the Fittest
• Force of Will
• Necropotence
• Kinnan, Bonder Prodigy
• Gaea's Cradle
• Mox Diamond
• Chrome Mox

Attribute Ratings:

Speed: 10/10
Capable of T1 wins (e.g., Ritual -> Consultation/Oracle) with consistent T2-3 goldfish.

Resilience: 9/10
8 free protection spells, 14 tutors, and 3 redundant infinite mana combos. Recovers easily from 1-2 disruptions.

Consistency: 10/10
14 tutors + 8 draw engines + 4 infinite mana lines. Sees entire deck by T4-5 regularly.

Interaction: 9/10
12 instant-speed answers including free counters and StP. Lacks mass artifact/enchantment removal beyond Boseiju.

Rating Justification:

This deck meets all cEDH Tier 1 benchmarks (T2-3 win/lock with near-unbreakable lines) but lacks the absolute fastest T1 density of true Tier 0. Compared to the rubric's 9.5 Tier 1 description, it sits just below due to slight reliance on creature-based combos.

Power level: 9.0 - 9.5
