Overview:

This Korvold, Fae-Cursed King deck is a high-speed sacrifice/combo build leveraging Treasure tokens, recursive engines, and efficient tutors to execute game-ending loops. Korvold serves as both a card advantage engine and a voltron threat, while hidden commanders like Witherbloom Apprentice and Underworld Breach enable explosive combo finishes. The deck prioritizes generating and sacrificing permanents for value, with multiple lines to assemble infinite loops or overwhelming board states.

Primer:

Core Strategy Execution:

1. Early Acceleration (Turns 1-2): Deploy fast mana (Elvish Spirit Guide, Orcish Lumberjack, Dark Ritual) or dorks (Ignoble Hierarch, Birds of Paradise). Use Crop Rotation/Entomb to set up key lands/graveyard targets.
2. Engine Setup (Turns 2-4): Cast Korvold or establish sacrifice outlets like Professional Face-Breaker. Generate Treasures with Impulsive Pilferer/Mayhem Devil and draw into combo pieces.
3. Win Conditions (Turns 3-6):
   • Infinite Drain: Chain of Smog + Witherbloom Apprentice (copied via Dualcaster Mage or Underworld Breach recursion).
   • Breach Lines: Underworld Breach + Lively Dirge/Final Fortune for infinite turns or storm kills.
   • Combat Overkill: Korvold with +1/+1 counters from sac triggers, amplified by Finale of Devastation or Chatterfang, Squirrel General.
   • Ad Nauseam: Draw most of the deck using life from Treasures/Necrodominance, then win via Walking Ballista (not listed but implied via tutors) or storm.

Mulligan Priorities:

• Keep hands with 2-3 lands, at least one ramp source (ritual/dork), and a combo piece or tutor.
• Prioritize hands with Underworld Breach + Lively Dirge or Witherbloom Apprentice + protection.
• Avoid hands lacking early mana or with only high-CMC cards.

Key Tips:

• Use Beseech the Mirror to fetch Underworld Breach or Ad Nauseam for free via Treasure sacrifice.
• Final Fortune + Underworld Breach creates extra turns to assemble combos.
• Culling Ritual clears opponents' boards while fueling Breach escapes or Korvold triggers.

Weaknesses:

Critical

• Graveyard hate (Rest in Peace, Leyline of the Void) cripples Breach, Lively Dirge, and reanimation lines.
• Rule of Law effects shut down storm/combo turns.
• Korvold-focused hands fold to repeated removal (taxes recast costs significantly).

Moderate

• Anti-token tech (Torpor Orb, Elesh Norn, Grand Cenobite) disrupts Treasure/sacrifice synergies.
• Life gain strategies outpace Witherbloom Apprentice drain.

Minor

• Limited flyer defense outside Mayhem Devil pings.
• Painland-heavy mana base risks self-damage against aggro.

Most Important Cards:

• Underworld Breach (Recursive combo enabler)
• Chain of Smog (Infinite loop with Witherbloom Apprentice)
• Ad Nauseam (Deck-draw engine for combo assembly)
• Witherbloom Apprentice (Primary combo payoff)
• Beseech the Mirror (Tutor for Breach/Nauseam)
• Final Fortune (Extra turn for combo setup)
• Diabolic Intent (Sacrifice-based tutor)
• Dualcaster Mage (Copies Chain of Smog or key spells)
• Mayhem Devil (Sacrifice-based removal/damage)
• Korvold, Fae-Cursed King (Card draw engine/voltron threat)

Attribute Ratings:

Speed: 8/10
Capable of T3-4 wins with perfect hands (e.g., Dark Ritual → Breach + Lively Dirge → Final Fortune loop). Average goldfish: T5-6.

Resilience: 6/10
Protection spells (Veil of Summer, Bolt Bend) and recursion (Breach, Eternal Witness) mitigate disruption, but graveyard reliance creates critical vulnerabilities.

Consistency: 7/10
12 tutors (including Beseech, Diabolic Intent, Green Sun’s Zenith) and Korvold’s draw power ensure frequent access to combo pieces, but lacks redundancy for Chain of Smog.

Interaction: 5/10
Efficient targeted removal (Assassin’s Trophy, Abrupt Decay) and stack interaction (Pyroblast, Imp’s Mischief), but light on board wipes and stax.

Rating Justification:

This deck operates at cEDH-adjacent speeds with T3-4 combo potential but lacks the interaction density and near-unbreakable wincons of top-tier lists. Its reliance on graveyard synergies and vulnerability to common hate cards cap its ceiling.

Power level: 7.5 - 8.0
