Overview:

This Omnath, Locus of Creation deck is a high-synergy landfall engine that leverages multiple extra land plays, graveyard recursion, and triggered ability doublers to generate overwhelming value. The commander serves as a critical accelerant and win condition, providing life gain, mana bursts, and direct damage via its third landfall trigger. The deck wins through token swarms (Avenger of Zendikar, Rampaging Baloths), combat overdrive (Moraug, Fury of Akoum, Akroma's Memorial), and triggered damage (Omnath, Locus of Rage), supported by robust land recursion and interaction.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Deploy land accelerators like Exploration, Azusa, Lost but Seeking, and Dryad of the Ilysian Grove to enable 3+ land drops per turn. Fetch duals/shocks with Farseek, Three Visits, and fetchlands.
2. Midgame Value (Turns 4-6): Resolve key doublers like Ancient Greenwarden and Elesh Norn, Mother of Machines to amplify landfall triggers. Generate tokens with Felidar Retreat or Greensleeves, Maro-Sorcerer, and refill with Sylvan Library or Tatyova, Benthic Druid.
3. Win Conditions (Turns 6-8):
   • Combat Overkill: Use Moraug, Fury of Akoum for extra combats, Akroma's Memorial for evasion, and Elesh Norn, Grand Cenobite for anthem effects.
   • Triggered Damage: Stack Omnath’s third landfall trigger with recursion loops (e.g., Oboro, Palace in the Clouds + Crucible of Worlds).
   • Token Swarm: Overwhelm with Avenger of Zendikar plants or Omnath, Locus of Rage Elementals.

Mulligan Priorities:

• Prioritize hands with 2-3 lands, at least one ramp spell (e.g., Exploration, Three Visits), and a value engine like The One Ring or Oracle of Mul Daya.
• Keep hands with fetchlands + Ramunap Excavator/Crucible of Worlds for recursive value.
• Avoid hands lacking green mana or early land plays.

Key Tips:

• Use Splendid Reclamation with fetchlands in the graveyard for explosive turns.
• Shifting Woodland can copy Field of the Dead or Ancient Greenwarden for late-game recursion.
• Heroic Intervention and Grand Crescendo protect against board wipes during critical turns.

Weaknesses:

Critical

• Graveyard Reliance: Rest in Peace or Leyline of the Void cripples recursion engines like Crucible of Worlds and Splendid Reclamation.
• Mass Land Destruction: Armageddon or Ruination resets the deck’s primary engine.

Moderate

• Anti-Token Effects: Cursed Totem/Torpor Orb nullify token generators and ETB synergies.
• Stax Effects: Blood Moon disrupts mana fixing; Confounding Conundrum limits land recursion.

Minor

• Spot Removal: Key pieces like Ancient Greenwarden or Elesh Norn, Mother of Machines are vulnerable, but the deck has redundancy.

Most Important Cards:

• Ancient Greenwarden (Doubles landfall triggers, enables recursion)
• Crucible of Worlds (Recurs fetchlands for repeated landfall)
• Omnath, Locus of Rage (Alternate wincon via token death triggers)
• Moraug, Fury of Akoum (Enables lethal combat phases)
• Elesh Norn, Mother of Machines (Doubles ETB triggers, disrupts opponents)
• Avenger of Zendikar (Primary token generator)
• Splendid Reclamation (Mass land recursion for explosive turns)
• Dryad of the Ilysian Grove (Enables extra land drops, fixes mana)
• The One Ring (Card advantage and protection)
• Heroic Intervention (Critical board protection)

Attribute Ratings:

Speed: 7/10

• Can threaten lethal via Moraug combats or Omnath triggers by T7-8, but lacks fast mana for earlier explosive turns.

Resilience: 6/10

• Recursion engines and protection spells mitigate setbacks, but core strategy is vulnerable to graveyard/land hate.

Consistency: 8/10

• 12 fetchlands, 8 land tutors, and 10+ card draw engines ensure reliable access to key pieces.

Interaction: 5/10

• Efficient spot removal (Swords to Plowshares, Path to Exile) and counterspells (Dovin's Veto), but lacks stack control for combo disruption.

Rating Justification:

This deck combines high consistency and synergistic power with landfall mechanics, capable of overwhelming tables by T7-8 through combat or triggered damage. While resilient to conventional removal, its critical weaknesses to graveyard hate and land destruction keep it below cEDH thresholds.

Power level: 6.5 - 7.0
