Overview:

This Kenrith, the Returned King deck is a high-speed, five-color combo list leveraging efficient two-card win conditions, fast mana, and cEDH-level interaction. The core strategy revolves around assembling Thassa’s Oracle + Demonic Consultation/Tainted Pact or Underworld Breach + Lion’s Eye Diamond/Brain Freeze, supported by redundant tutors, free counterspells, and infinite mana/flicker lines with Dockside Extortionist/Emiel the Blessed.

Primer:

Core Strategy:
Deploy fast mana (Mana Crypt, Lion’s Eye Diamond) to cast tutors (Demonic Tutor, Imperial Seal) or combo pieces by turns 1–3. Win via:

1. Oracle/Consultation: Exile library with Demonic Consultation/Tainted Pact to trigger Thassa’s Oracle.
2. Breach Lines: Loop Brain Freeze/Wheel of Fortune with Underworld Breach and LED.
3. Infinite Mana: Dockside Extortionist + Emiel the Blessed/Displacer Kitten generates infinite mana/Treasure, enabling Kenrith’s abilities to draw the deck or reanimate Oracle.

Mulligan Priorities:

• Keep hands with fast mana + tutor/combo piece.
• Prioritize free interaction (Force of Will, Mental Misstep) if holding a combo.
• Avoid hands without mana acceleration or combo potential.

Key Tips:

• Use Kenrith’s reanimation (4B ability) to retrieve disrupted combo pieces.
• Chain Wishclaw Talisman activations with Opposition Agent to steal opponents’ wins.
• Underworld Breach + LED enables casting multiple tutors/interaction from the graveyard.

Weaknesses:

Critical

• Graveyard Reliance: Folded by Rest in Peace, Leyline of the Void.
• Glass Cannon Combos: Oracle/Consultation disrupted by counterspells or instant-speed exile.

Moderate

• Stax Vulnerabilities: Rule of Law/Drannith Magistrate blocks combo assembly.

Minor

• Life Loss: Demonic Consultation, Mana Crypt, fetchlands pressure life total.

Most Important Cards:

• Thassa's Oracle
• Demonic Consultation
• Underworld Breach
• Lion’s Eye Diamond
• Dockside Extortionist
• Tainted Pact
• Force of Will
• Demonic Tutor
• Vampiric Tutor
• Opposition Agent

Attribute Ratings:

Speed: 9/10

• T1–2 wins possible with perfect draws (e.g., T1 LED + Breach + Brain Freeze).

Resilience: 8/10

• 10+ free/low-cost counterspells, recursion via Breach/Kenrith, but combos remain disruptable.

Consistency: 9/10

• 12+ tutors, 5+ card-draw engines (Rhystic Study, The One Ring).

Interaction: 9/10

• S-tier counters (Force cycle, An Offer You Can’t Refuse) and removal (Swords to Plowshares).

Rating Justification:

This deck operates at cEDH Tier 1 levels with T1–3 win potential, redundant combos, and robust interaction, but lacks the near-universal stax resilience of true Tier 0 lists.

Power level: 9.0 - 9.5
