Overview:

This Omnath, Locus of Creation deck leverages explosive landfall synergies and mass land recursion to fuel overwhelming value, mana acceleration, and game-ending threats. Omnath serves as the engine, providing life gain, rainbow mana bursts, and a repeatable damage trigger when three lands enter in a turn. The strategy combines aggressive ramp, land destruction (via Armageddon/Strip Mine paired with recursion from World Shaper/Ramunap Excavator), and massive payoffs like Avenger of Zendikar, Scute Swarm, and Eldrazi titans. Tutors and card advantage engines ensure consistent access to key pieces.

Primer:

Core Strategy Execution:

1. Early Ramp (T1-3): Deploy fast mana (Sol Ring, Mana Vault, Bloom Tender) and land accelerators like Arboreal Grazer, Azusa, or Oracle of Mul Daya to enable 3+ land drops per turn.
2. Omnath Setup (T3-5): Cast Omnath to start chaining landfall triggers. Use Dryad of the Ilysian Grove or Ancient Greenwarden to amplify triggers. Prioritize hitting the third landfall trigger each turn for 12 damage to all opponents.
3. Lock/Overrun (T5-8):
   • Combat Wins: Flood the board with tokens via Scute Swarm/Avenger of Zendikar and buff them with Felidar Retreat.
   • Land Destruction: Cast Armageddon with World Shaper/Ramunap Excavator in play to cripple opponents while rebuilding your mana.
   • Eldrazi Finishers: Cheat out Ulamog/Kozilek via Finale of Devastation or Chord of Calling for annihilator pressure.

Mulligan Priorities:

• Keep hands with 2-3 lands, at least one ramp piece (e.g., Sol Ring, Arboreal Grazer), and a landfall enabler (Azusa, Oracle of Mul Daya).
• Prioritize early interaction (Force of Negation, Fierce Guardianship) in metas with heavy combo.
• Avoid hands lacking land drops or reliant solely on high-CMC threats.

Key Tips:

• Use Crop Rotation to fetch Glacial Chasm for protection or Boseiju to disrupt opponents.
• Ashaya, Soul of the Wild turns creatures into lands, enabling infinite landfall with Quirion Ranger-like effects (though absent here, it still amplifies triggers).
• Heroic Intervention protects your board during critical Armageddon or Scute Swarm turns.

Weaknesses:

Critical

• Graveyard hate (Rest in Peace, Leyline of the Void) cripples land recursion and Eldrazi reshuffling.
• Omnath removal loops: Repeatedly killing Omnath before landfall triggers resolve stalls mana/damage output.

Moderate

• Blood Moon effects disrupt nonbasic land synergies (e.g., Dryad of the Ilysian Grove, shocklands).
• Mass artifact removal (Vandalblast) hits critical mana sources like Chromatic Lantern/Mana Vault.

Minor

• Flying threats can bypass ground defenses, though Felidar Retreat’s vigilance helps.
• Stack-based interaction can disrupt key sorcery-speed plays like Armageddon.

Most Important Cards:

• Omnath, Locus of Creation (Engine: mana, damage, card draw)
• Armageddon (Lock piece with land recursion)
• World Shaper/Ramunap Excavator (Land recursion for Armageddon parity)
• Dryad of the Ilysian Grove (Land drop doubling + fixing)
• Finale of Devastation (Tutor + Overrun)
• Avenger of Zendikar (Token generator)
• Ancient Greenwarden (Landfall trigger doubler)
• Force of Negation/Fierce Guardianship (Free interaction)
• Ashaya, Soul of the Wild (Land synergy amplifier)
• Scute Swarm (Scaling threat)

Attribute Ratings:

Speed: 7/10

• Can deploy game-ending threats or locks by T6-7 via explosive ramp and Armageddon recursion.

Resilience: 6/10

• Recursion and protection spells mitigate setbacks, but reliance on Omnath and graveyard creates vulnerabilities.

Consistency: 8/10

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

Interaction: 6/10

• Efficient counterspells and targeted removal, but limited stack control beyond protecting its own plays.

Rating Justification:

This deck operates at a 6.5 - 7.0 power level, aligning with "Focused Competitive" to "Highly Optimized" tiers. Its T6-7 win/lock potential via land destruction or token overruns is supported by exceptional consistency and tutor density, but graveyard reliance and commander dependency prevent higher-tier viability.

Power level: 6.5 - 7.0
