Overview:

This 5-color deck leverages a high-powered mana base and combo synergies to generate overwhelming value and win through infinite mana combos, stolen spells, and potent creature threats. While helmed by O-Kagachi, Vengeful Kami, the commander serves more as a political deterrent/removal engine than a core strategy. The real power lies in untap combos with Zaxara, the Exemplary, Bloom Tender, and Freed from the Real/Pemmin's Aura, enabling game-ending Villainous Wealth casts or massive Hydra tokens. Secondary themes include Nightmare/Horror tribal synergies (Umbris, Fear Manifest, Chainer, Dementia Master) and a robust interaction suite.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy fast mana (Chrome Mox, Grim Monolith, Sol Ring) and fix colors with fetch lands/duals. Cast Rhystic Study or Smothering Tithe for early advantage.
2. Combo Assembly (Turns 4-5): Resolve Zaxara, the Exemplary or Bloom Tender with protection (Lightning Greaves). Pair with Freed from the Real/Pemmin's Aura to generate infinite mana. Use Training Grounds to reduce activation costs.
3. Win Execution:
   • Infinite mana → Cast Villainous Wealth for X=20+ to steal opponents' decks.
   • Zaxara + infinite mana → Create infinitely large Hydra tokens.
   • Umbris, Fear Manifest + forced exile effects (Ashiok planeswalkers) for lethal commander damage.
4. Alternative Lines: Reanimate threats with Chainer, Dementia Master, control via Cyclonic Rift overload, or drain with Consecrated Sphinx/Slitherwisp card advantage.

Mulligan Priorities:

• Keep hands with 2+ lands (including color-fixing), at least one ramp piece (Bloom Tender, Sol Ring), and a combo component or tutor.
• Prioritize hands with early interaction (Force of Will, Deadly Rollick) in unknown metas.
• Avoid slow hands lacking color fixing or proactive plays.

Key Tips:

• Use Freed from the Real on Bloom Tender with 3+ colored permanents for infinite mana.
• Teferi's Protection protects against board wipes during combo setup.
• Vampiric Tutor/Imperial Seal can top-deck combo pieces for Seedborn Muse untap synergy.
• Urborg, Tomb of Yawgmoth + Dread Presence provides incremental value and removal.

Weaknesses:

Critical

• Fragile Combo Pieces: Zaxara, Bloom Tender, and untap auras have no innate protection and are priority removal targets.
• Anti-Ability Hate: Cursed Totem/Collector Ouphe cripple mana dorks and combo lines.

Moderate

• Graveyard Reliance: Chainer, Dementia Master and recursion tools fold to Rest in Peace/Leyline of the Void.
• Stack Interaction: Limited counterspells beyond Force of Will/Mana Drain; struggles against resolved stax like Rule of Law.

Minor

• High Life Payment: Mana Confluence, City of Brass, and Necropotence-style effects can lower life totals dangerously.

Most Important Cards:

• Zaxara, the Exemplary (Primary combo engine)
• Freed from the Real (Infinite mana enabler)
• Villainous Wealth (Game-ending payoff)
• Bloom Tender (Mana multiplier/combo piece)
• Demonic Tutor (Tutoring critical components)
• Cyclonic Rift (Board reset/emergency valve)
• Seedborn Muse (Untap synergy for combos)
• Training Grounds (Cost reduction for activated abilities)
• Umbris, Fear Manifest (Alternate voltron threat)
• Rhystic Study (Card advantage engine)

Attribute Ratings:

Speed: 8/10

• Capable of T4-5 wins with ideal draws (e.g., T1 ramp → T2 Bloom Tender → T3 Freed from the Real + infinite mana).

Resilience: 6/10

• Strong counterspell/protection suite but relies on resolving fragile creatures. Recovers well with tutors and card advantage.

Consistency: 7/10

• 10+ tutors and robust draw engines ensure combo access, but 5-color requirements can occasionally strain mana.

Interaction: 8/10

• Packed with premium removal (Swords to Plowshares, Deadly Rollick) and counterspells (Force of Negation, Mana Drain).

Rating Justification:

This deck operates at cEDH-adjacent speeds with T4-5 win potential through resilient combos and exceptional interaction, but its reliance on creature-based engines and vulnerability to common stax pieces place it just below top tiers. The optimized mana base and redundancy warrant a high-power rating.

Power level: 7.5 - 8.0
