Overview:

This Muldrotha, the Gravetide deck leverages Sultai's graveyard synergies to create a resilient value engine with multiple combo finishers. The commander enables recursive casting of permanents like Mystic Remora, Seal of Primordium, and combo pieces from the graveyard. The deck employs land-based threats (Dark Depths + Thespian's Stage), creature combos (Mikaeus, the Unhallowed + Triskelion), and storm payoffs (Tendrils of Agony, Brain Freeze), supported by high-quality tutors and free interaction. Muldrotha acts as both a value engine and combo enabler, allowing the deck to pivot between grindy recursion and explosive wins.

Primer:

Core Strategy Execution:

1. Early Setup (T1-3): Deploy mana acceleration (Exploration, Arbor Elf, Lotus Petal), set up card advantage engines (Rhystic Study, Mystic Remora), and mill/discard key pieces using Entomb/Intuition.
2. Midgame Value (T4-6): Recur permanents with Muldrotha, using Eternal Witness/Timeless Witness to rebuy key spells. Deploy land combos (copy Dark Depths with Thespian's Stage/Vesuva) or assemble creature combos via Fiend Artisan/Finale of Devastation.
3. Win Conditions:
   • Infinite Damage: Mikaeus, the Unhallowed + Triskelion (sacrifice loop)
   • Marit Lage: Dark Depths + land-copy effects
   • Storm: Displacer Kitten + noncreature spells into Brain Freeze/Tendrils of Agony
   • Torment Lock: Recurring Torment of Hailfire via Animate Dead/Kaya's Ghostform

Mulligan Priorities:

• Keep hands with 2-3 lands, at least one ramp source (Sol Ring, Arbor Elf), and either a tutor (Demonic Tutor, Intuition) or card engine (Rhystic Study, Sylvan Library).
• Prioritize hands containing Dark Depths + land copier or Entomb for early combo setup.
• Avoid hands lacking graveyard enablers or with only high-CMC cards.

Key Tips:

• Use Displacer Kitten to reset Muldrotha's casting limit or flicker Eternal Witness for recursive tutoring.
• Life from the Loam fuels both Field of the Dead and Cabal Coffers/Urborg, Tomb of Yawgmoth synergies.
• Opposition Agent + Realms Uncharted steals opponents' best lands while binning your Dark Depths/Glacial Chasm.

Weaknesses:

Critical

• Graveyard hate (Rest in Peace, Leyline of the Void) completely shuts down Muldrotha's recursion and combo lines.
• Drannith Magistrate/Containment Priest blocks Muldrotha's casting-from-graveyard ability and creature recursion.

Moderate

• Fast artifact-based combos can outpace this deck's interaction suite.
• Blood Moon effects disrupt the greedy 5C mana base enabled by Urborg/Yavimaya.

Minor

• Limited instant-speed answers to resolved enchantments outside Seal of Primordium.
• Test of Talents-effects can exile key storm spells.

Most Important Cards:

• Mikaeus, the Unhallowed (Primary combo enabler)
• Dark Depths (Land-based win condition)
• Demonic Tutor (Tutoring flexibility)
• Displacer Kitten (Value engine/combo piece)
• Intuition (Graveyard setup/3-card tutor)
• Force of Will (Free interaction)
• Life from the Loam (Land recursion engine)
• Opposition Agent (Disruption + tutor theft)
• Rhystic Study (Card advantage)
• Toxic Deluge (Board wipe)

Attribute Ratings:

Speed: 8/10
Capable of T3 Marit Lage (with perfect ramp) or T4-5 Mikaeus combos, but typically wins T5-7 through layered value.

Resilience: 7/10
Multiple recursion engines and free counterspells (Force of Will, Force of Negation) protect key plays, but relies heavily on graveyard access.

Consistency: 9/10
12 tutors, 8 card-advantage engines, and redundant combo lines ensure reliable access to win conditions.

Interaction: 8/10
Premium counterspells, targeted removal (Assassin's Trophy), and stax pieces (Opposition Agent) disrupt opponents effectively.

Rating Justification:

This deck operates at cEDH-adjacent speeds (T3-5 wins) with high-quality interaction and redundancy but lacks the deterministic T1-2 lines of top-tier cEDH. Its reliance on the graveyard and slightly slower mana base compared to fully optimized lists place it just below Tier 1 competitiveness.

Power level: 8.0 - 8.5
