Overview:

This Rashmi and Ragavan deck is a high-octane, artifact-driven combo machine leveraging fast mana, free interaction, and multiple infinite loops to secure early victories. The commanders serve as a value engine, generating Treasures and casting opponents' spells, but the core strategy revolves around assembling game-ending combos like Thassa's Oracle/Brain Freeze, Time Vault/Voltaic Key, and Underworld Breach recursion. With unrestricted access to Power 9 cards and cEDH staples, it operates at blistering speeds.

Primer:

Core Strategy Execution:

1. Explosive Start (Turns 0-1): Deploy fast mana (Mox Diamond, Lion's Eye Diamond, Mana Crypt) to cast Rashmi and Ragavan early or dig for combo pieces. Use Ancestral Recall, Time Walk, or Tinker to accelerate.
2. Combo Assembly (Turns 1-3): Tutor for Thassa's Oracle (via Worldly Tutor/Mystical Tutor), Time Vault (via Tinker), or Underworld Breach. Pair with Brain Freeze (storm off with fast mana), Voltaic Key, or Lion's Eye Diamond for infinite loops.
3. Protection & Disruption: Counter key interaction with Force of Will, Deflecting Swat, and Mental Misstep. Use Hullbreaker Horror to bounce threats while advancing your board.
4. Alternative Lines: Leverage Panoptic Mirror imprinted with Time Walk, Paradox Engine untaps, or Kinnan, Bonder Prodigy to cheat out Emrakul, the Aeons Torn.

Mulligan Priorities:

• Keep hands with 1-2 lands + 2+ fast mana artifacts.
• Prioritize combos: e.g., Tinker + artifact sacrifice target.
• Ensure interaction (Force effects) if combo pieces are present.

Key Tips:

• Use Underworld Breach with Lion's Eye Diamond and Brain Freeze for deterministic storm kills.
• Gilded Drake steals opponents' commanders to disrupt their strategies.
• Hullbreacher punishes opponents' draws while fueling your Treasure count for Rashmi triggers.

Weaknesses:

Critical

• Artifact hate (Null Rod, Stony Silence) shuts down 80% of the deck's mana and combos.
• Graveyard exile (Rest in Peace) neuters Underworld Breach and recursion.

Moderate

• Rule of Law effects limit spell chains and combo turns.
• Speed races (e.g., faster cEDH decks like K'rrik, Son of Yawgmoth).

Minor

• Limited board presence makes it vulnerable to aggressive starts (rare in high-power metas).

Most Important Cards:

• Thassa's Oracle (Primary win condition)
• Underworld Breach (Recursion engine/combo piece)
• Time Vault (Infinite turns with Voltaic Key/Paradox Engine)
• Lion's Eye Diamond (Mana source/Breach fuel)
• Tinker (Tutors Time Vault or Aetherflux Reservoir)
• Force of Will (Free interaction)
• Mana Crypt (Turn 0 acceleration)
• Brain Freeze (Storm wincon with Breach)
• Black Lotus (Unrestricted fast mana)
• Hullbreaker Horror (Disruption + combo potential)

Attribute Ratings:

Speed: 10/10

• Capable of T1 wins (e.g., Lotus + Tinker for Time Vault + Voltaic Key) and consistent T2-3 victories.

Resilience: 8/10

• 12+ free interaction spells protect combos, and Breach provides graveyard recursion. However, relies heavily on artifacts.

Consistency: 9/10

• 8 tutors, ample card draw (Rhystic Study, Ancestral Recall), and redundant combo lines ensure reliability.

Interaction: 9/10

• 14 counterspells/redirects, including free casts (Deflecting Swat, Force of Negation), and bounce effects.

Rating Justification:

This deck operates at cEDH Tier 0 velocity with unrestricted access to Power 9 and multiple T1 win lines, but its reliance on artifacts and graveyard mechanics slightly reduces its resilience compared to fully optimized Tier 0 lists. The inclusion of banned cards (e.g., Black Lotus) pushes it beyond conventional EDH power scales.

Power level: 9.5 - 10.0
