Overview:

This Simic +1/+1 counters deck helmed by Sab-Sunen, Luxa Embodied focuses on explosive mana acceleration and counter proliferation to create overwhelming board states. The commander serves as a persistent proliferate engine, synergizing with counter-generating creatures like Master Biomancer, Mossborn Hydra, and Goldvein Hydra. The deck employs multiple infinite mana combos (Kinnan, Bonder Prodigy + Basalt Monolith, Ashaya, Soul of the Wild + untappers) to fuel game-ending plays via Genesis Wave, Rishkar's Expertise, or The Great Henge. Secondary win conditions include combat damage through massive tramplers enhanced by Kodama of the West Tree and Ozolith, the Shattered Spire.

Primer:

Core Strategy Execution:

1. Ramp Phase (Turns 1-3): Deploy mana dorks (Llanowar Elves, Birds of Paradise), land-based ramp (Nature's Lore, Skyshroud Claim), and counter enablers (Hardened Scales, Branching Evolution).
2. Engine Setup (Turns 3-5): Cast Sab-Sunen to begin proliferating counters. Use Seedborn Muse or Emergence Zone for instant-speed proliferation. Activate Gaea's Cradle/Growing Rites of Itlimoc for explosive mana.
3. Win Execution (Turns 4-7):
   • Combo: Generate infinite mana via Kinnan/Monolith or Ashaya/untappers. Dump mana into Genesis Wave for permanent flood or Walking Ballista (via tutors).
   • Combat: Deploy Vorinclex, Monstrous Raider-enhanced threats with Rogue's Passage evasion. Use Wrenn and Seven for land-based token scaling.

Mulligan Priorities:

• Keep hands with 2-3 lands including green sources.
• Prioritize early ramp (1-2 CMC dorks/auras) and at least one counter generator.
• Favor hands containing Kinnan, Bonder Prodigy, Seedborn Muse, or The Great Henge.

Key Tips:

• Use Agatha's Soul Cauldron to grant key abilities (e.g., Incubation Druid's adapt) from the graveyard.
• Court of Garenbrig provides both counter synergy and emergency mana.
• Activate Karn's Bastion during opponents' turns with Seedborn Muse for quadruple proliferation per cycle.

Weaknesses:

Critical

• Relies heavily on creature-based mana sources vulnerable to Wrath of God/Toxic Deluge.
• Cursed Totem/Collector Ouphe shuts down Kinnan, dorks, and Ozolith activations.

Moderate

• Limited instant-speed interaction for resolved noncreature threats.
• Drannith Magistrate blocks commander casts and Kinnan activations.

Minor

• Weak to The One Ring-style card advantage outpacing its board presence.
• Darksteel Mutation on Sab-Sunen delays proliferate engine.

Most Important Cards:

• Kinnan, Bonder Prodigy (Infinite mana enabler)
• Seedborn Muse (Untap engine)
• The Great Henge (Card advantage + counter synergy)
• Ashaya, Soul of the Wild (Combo piece + mana scaling)
• Vorinclex, Monstrous Raider (Counter doubling)
• Basalt Monolith (Infinite mana component)
• Worldly Tutor (Key creature fetcher)
• Gaea's Cradle (Mana explosion)
• Genesis Wave (Primary payoff spell)
• Emergence Zone (Instant-speed proliferation)

Attribute Ratings:

Speed: 8/10

• Capable of T3-4 infinite mana (Kinnan/Monolith) into T4-5 wins, with consistent T6-7 combat kills.

Resilience: 6/10

• Multiple protection spells (Heroic Intervention, Slip Out the Back) and recursion (Wrenn and Seven), but core strategy remains creature-dependent.

Consistency: 9/10

• 14 tutors/card selection pieces (Sylvan Library, Chord of Calling) paired with Simic's inherent draw power.

Interaction: 5/10

• Efficient counterspells (Force of Will, Fierce Guardianship) and targeted removal (Rapid Hybridization), but lacks board wipes.

Rating Justification:

This deck achieves cEDH-adjacent speed with multiple T4 win lines and exceptional consistency, but its creature-centric strategy and vulnerability to common stax pieces prevent it from reaching tiered cEDH reliability. The robust interaction suite and fast mana push it above typical high-power casual.

Power level: 7.5 - 8.0
