Overview:

This Dimir deck helmed by Emet-Selch, Unsundered is a high-octane cEDH-compatible list focused on executing the Thassa's Oracle + Demonic Consultation/Tainted Pact combo with blistering speed. The commander primarily serves as a value engine for graveyard recursion post-transformation, but the deck doesn't rely on it for its primary win condition. Instead, it leverages an extensive suite of free interaction, premium tutors, and explosive mana acceleration to threaten wins as early as Turn 1 while maintaining robust protection. Secondary lines include Walking Ballista with infinite mana (via Basalt Monolith + Retraction Helix/Displacer Kitten loops) and storm-based Brain Freeze kills.

Primer:

Core Strategy Execution:

1. Turbo Setup (Turns 0-2): Deploy fast mana (Mana Vault, Mox Opal, Dark Ritual) to power out tutors (Demonic Tutor, Vampiric Tutor) or directly cast Ad Nauseam/Necropotence for rapid card advantage.
2. Combo Assembly (Turns 1-3): Use Demonic Consultation/Tainted Pact to exile the library, then cast Thassa's Oracle with priority retention. Protect with free counterspells (Force of Will, Fierce Guardianship).
3. Alternative Lines: Leverage Krark-Clan Ironworks/Ashnod's Altar with Nim Deathmantle for infinite mana loops, or chain Brain Freeze storm copies with Borne Upon a Wind flash enablers.

Mulligan Priorities:

• Keep hands with at least 1 fast mana source (Mox Amber, Lotus Petal, Mana Vault) + tutor or combo piece.
• Prioritize blue sources for free counterspell protection.
• Snap-keep hands with T1 Demonic Consultation + Thassa's Oracle enablers.

Key Tips:

• Cast Necropotence pre-combo turn to dig for protection/outlets.
• Use Emergence Zone to flash in Thassa's Oracle during end steps after exiling your library.
• Displacer Kitten + Basalt Monolith generates infinite mana with noncreature spell casts.

Weaknesses:

Critical

• Folded by Opposition Agent shutting off tutors/consults.
• Mindbreak Trap exiles critical storm/combo spells.

Moderate

• Graveyard hate (Rest in Peace) disrupts Hades' recursion value.
• Rule of Law effects slow storm lines.

Minor

• Drannith Magistrate blocks commander-based recursion.
• Life total pressure from Necropotence/Ancient Tomb can be exploited.

Most Important Cards:

• Thassa's Oracle (Primary win condition)
• Demonic Consultation (Library exile enabler)
• Force of Will (Free combo protection)
• Ad Nauseam (Turn 0-2 card advantage engine)
• Mana Vault (Critical fast mana)
• Necropotence (Unrestricted card selection)
• Tainted Pact (Alternative library exile)
• Mystical Tutor (Flexible instant-speed setup)
• Demonic Tutor (Premium consistency tool)
• Borne Upon a Wind (Enables surprise combo execution)

Attribute Ratings:

Speed: 10/10
Capable of T1 wins with perfect draws (e.g., Dark Ritual → Demonic Consultation + Thassa's Oracle), regularly threatens T2-3 kills.

Resilience: 8/10
12 free interaction spells (including Force of Negation, Fierce Guardianship) protect combos, but relies heavily on drawing them.

Consistency: 9/10
14 tutors and extreme card draw (Necropotence, The One Ring) ensure combo access.

Interaction: 9/10
Potent stack control with Force of Will, Mental Misstep, and Deadly Rollick, plus board wipes like Toxic Deluge.

Rating Justification:

This deck operates at cEDH's highest tiers, boasting T1-2 win potential with layered protection and extreme consistency. While slightly less deterministic than fully optimized Thrasios/Tymna builds, its speed and redundancy justify a top-tier rating.

Power level: 9.0 - 9.5
