Overview:

This four-color Omnath, Locus of Creation deck is a high-powered landfall engine that leverages explosive ramp, land recursion, and massive value generation to dominate the board. Omnath serves as the linchpin, enabling life gain, mana acceleration, and a repeatable burn effect via its third landfall trigger. The deck combines fast mana, land-based combos (e.g., Ashaya, Soul of the Wild + Quirion Ranger effects), and overwhelming token generation (Avenger of Zendikar, Scute Swarm) to pressure opponents. Secondary win conditions include Eldrazi annihilation (Kozilek, Butcher of Truth, Ulamog, the Infinite Gyre) and Armageddon locks paired with recursion like World Shaper.

Primer:

Core Strategy Execution:

1. Early Acceleration (Turns 1-3): Deploy fast mana (Mana Vault, Lotus Petal, Chrome Mox) and extra land enablers (Exploration, Azusa, Lost but Seeking). Fetch critical lands (Dryad Arbor, Yavimaya, Cradle of Growth) to maximize color fixing.
2. Omnath Setup (Turns 3-4): Cast Omnath with protection (Silence, Force of Will). Trigger its first two landfall abilities to stockpile mana and stabilize life totals.
3. Landfall Domination (Turns 4-6): Chain extra land drops with Oracle of Mul Daya, Ancient Greenwarden, or Kodama of the East Tree. Generate tokens via Scute Swarm/Felidar Retreat and burn opponents with Omnath’s third landfall.
4. Lock/Finish: Resolve Armageddon with Ramunap Excavator/World Shaper in play, or cheat Eldrazi using Finale of Devastation/Green Sun's Zenith.

Mulligan Priorities:

• Keep hands with 2+ lands, at least one ramp piece (e.g., Sol Ring, Exploration), and a land tutor (Crop Rotation, Three Visits).
• Prioritize fast mana (Mox Diamond, Mana Vault) in aggressive metas.
• Avoid hands lacking green sources or with excessive high-CMC cards.

Key Tips:

• Use Crop Rotation to fetch Glacial Chasm against aggro or Boseiju, Who Endures to disrupt opponents.
• Ashaya, Soul of the Wild turns creatures into Forests, enabling infinite landfall with Quirion Ranger-like effects.
• Kodama of the East Tree + Scute Swarm creates exponential token generation.

Weaknesses:

Critical

• Commander Dependency: Omnath’s third landfall is the primary wincon; repeated removal cripples tempo.
• Nonbasic Land Hate: Blood Moon/Back to Basics nullifies color fixing and synergies.
• Graveyard Reliance: Rest in Peace/Leyline of the Void shuts off recursion engines like Ramunap Excavator.

Moderate

• Stax Effects: Root Maze slows land deployment; Torpor Orb negates ETB triggers from Avenger/Scute Swarm.
• Mass Artifact Removal: Vandalblast disrupts fast mana critical for early Omnath casts.

Minor

• Fliers: Limited reach outside Reality Shift and Cyclonic Rift.
• Hand Disruption: Opposition Agent can intercept land tutors.

Most Important Cards:

• Omnath, Locus of Creation (Primary engine and wincon)
• Ashaya, Soul of the Wild (Combo enabler, land synergy)
• Ancient Greenwarden (Landfall doubler, recursion)
• Armageddon (Game-ending lock with recursion)
• Avenger of Zendikar (Token generator)
• Scute Swarm (Exponential token threat)
• Mana Vault (Critical fast mana)
• Force of Will (Free interaction)
• World Shaper (Post-wipe recovery)
• Cyclonic Rift (Board reset)

Attribute Ratings:

Speed: 8/10

• Capable of T3 Omnath into T4-5 lethal landfall triggers or Eldrazi via Mana Vault/Jeska's Will.

Resilience: 6/10

• Counterspells and recursion mitigate disruption, but commander reliance and artifact-heavy ramp create vulnerabilities.

Consistency: 8/10

• 12+ land tutors, 8+ card draw engines (e.g., Rhystic Study, The One Ring), and redundancy in land drops ensure key pieces are accessed.

Interaction: 7/10

• Robust countermagic (Force of Negation, Fierce Guardianship) and targeted removal (Path to Exile, Boseiju), but lacks board wipes beyond Cyclonic Rift.

Rating Justification:

This deck operates at cEDH-adjacent speeds (T4-5 wins via landfall burns or Eldrazi) with high consistency but falters against dedicated stax or commander removal. Its resilience and interaction suite place it just below top-tier competitive lists.

Power level: 7.5 - 8.0
