Overview:

This Omnath, Locus of All deck combines Phyrexian tribal synergies with high-value Praetor effects and stax elements. The strategy focuses on ramping into overwhelming board states using Omnath's mana acceleration, then locking out opponents with enter-tapped effects and triggered ability suppression. Win conditions include Praetor value engines, proliferated poison counters, and reanimation of massive threats like multiple Atraxas.

Primer:

Core Strategy:
This deck aims to cast Omnath by turn 4 using basic-heavy mana and artifacts like Chromatic Lantern, leveraging its mana conversion ability to fuel explosive plays. Key phases:

• Early Setup (T1-3): Deploy mana rocks, stax pieces like Drannith Magistrate, and value creatures like Dune Mover.
• Midgame Domination (T4-6): Resolve Praetors (Jin-Gitaxias, Progress Tyrant, Elesh Norn, Grand Cenobite) using Omnath's triggered ability to cheat on mana costs. Use proliferate engines (Bloated Contaminator) to accelerate poison and planeswalker ultimates.
• Endgame Locks: Combine Phyrexian Censor with Elesh Norn, Mother of Machines to suppress opponent actions, then overwhelm with recursive threats from Realmbreaker, the Invasion Tree and Breach the Multiverse.

Key Interactions:

• Elesh Norn, Mother of Machines doubles ETB triggers of Praetors and Incubator tokens
• The Seedcore enables casting Phyrexians through color restrictions
• Vorinclex, Monstrous Raider amplifies poison counters and planeswalker loyalty

Mulligan Priorities:

• Keep hands with 3 lands including at least one black source
• Prioritize early ramp (Sol Ring, Arcane Signet) or stax pieces
• Reject hands without colored mana fixing for Omnath's WUBRG cost

Weaknesses:

Critical:

• Heavy basic land distribution (8 Plains) creates color-screw risk for Omnath's casting
• No infinite combos - relies on slow poison/combat wins
• 80% of threats vulnerable to Farewell-type exile effects

Moderate:

• Limited graveyard recursion beyond Reanimate
• No free counterspells to protect key plays

Minor:

• Strong vs creature decks but weak to spell-based combos

Most Important Cards:

• Elesh Norn, Mother of Machines
• Jin-Gitaxias, Progress Tyrant
• Demonic Tutor
• Vampiric Tutor
• Mana Drain
• Defense of the Heart
• Realmbreaker, the Invasion Tree
• Atraxa, Grand Unifier
• Phyrexian Censor
• Cyclonic Rift

Attribute Ratings:

Speed: 6/10

• Can deploy game-warping Praetors by T5-6
• Lacks fast mana (no Crypt/Vault) or T3 combo potential

Resilience: 5/10

• Multiple Praetors provide redundancy
• Vulnerable to early board wipes before establishing recursion

Consistency: 7/10

• 6 tutors find key pieces
• Omnath's card selection smooths draws

Interaction: 8/10

• Premium removal (Swords, Go for Throat)
• Counterspell suite (Mana Drain, Counterspell)
• Stax elements disrupt opponents

Rating Justification:

This deck sits between Optimized Casual (5.5) and Focused (6.0) on the rubric. While it lacks cEDH-speed combos, the combination of efficient tutors, high-quality interaction, and Praetor value engines exceeds typical precon power. The T6-8 win window through stax-enhanced combat damage aligns with 5.5-6.0 benchmarks. It struggles against faster combo decks but dominates midrange battlecruiser metas.

Power level: 5.5 - 6.0
