Overview:

This Simic +1/+1 counters deck leverages Tanazir Quandrix to amplify creature stats through counter doubling and base power/toughness manipulation. The strategy focuses on explosive growth of creatures like Wildwood Scourge and Ambitious Dragonborn, supported by counter multipliers like Branching Evolution and Ozolith, the Shattered Spire. Tanazir acts as both a finisher (via its attack trigger) and a value engine when paired with token generators like Blade of Selves. Secondary win conditions include Tyrranax Rex poison kills and a fragile infinite mana combo using Kami of Whispered Hopes + Staff of Domination.

Primer:

Core Strategy Execution:

1. Early Ramp (T1-4): Deploy mana dorks (Llanowar Elves, Birds of Paradise), Utopia Sprawl, and artifact ramp to accelerate into Tanazir by T3-4.
2. Counter Synergy (T3-5): Drop counter engines like Kami of Whispered Hopes or Fathom Mage, then play scalable threats (Wildwood Scourge, Rot Shambler). Use Ezuri, Stalker of Spheres for proliferate triggers.
3. Commander Payoff (T5+): Cast Tanazir to double counters on a key creature, then attack to set all creatures' base stats to Tanazir's power. Clone Tanazir via Blade of Selves or Helm of Host for exponential growth.
4. Win Conditions:
   • Combat: Overwhelm with 20/20+ creatures enhanced by Sword of Forge and Frontier evasion.
   • Poison: Tyrranax Rex attacks for Toxic 4 with Tanazir's stat boost.
   • Combo: With 3+ power on Kami, generate infinite mana via Staff untap loops, then draw deck with Staff/Toski.

Mulligan Priorities:

• Keep hands with 2-3 lands, 1-2 ramp pieces, and at least one counter engine or scalable creature.
• Prioritize Swiftfoot Boots/Heroic Intervention against removal-heavy pods.
• Avoid hands lacking green mana sources or early plays.

Key Tips:

• Clone Tanazir post-combat to preserve stat-setting triggers.
• Use Strionic Resonator to copy Tanazir's ETB or attack trigger.
• Vorel of the Hull Clade doubles counters on Ozolith or key creatures during opponents' turns.

Weaknesses:

Critical

• Extreme vulnerability to board wipes (only 2 mass protection spells).
• Cursed Totem/Torpor Orb shuts down mana dorks, Kami, and ETB value.

Moderate

• Relies heavily on Tanazir staying alive to enable stat-swings.
• Limited stack interaction (only 4 counterspells/removal).

Minor

• Weak to flyers without Poison Dart Frog activation.
• Combo lines require multiple unprotected pieces.

Most Important Cards:

• Branching Evolution (Counter multiplier)
• Kami of Whispered Hopes (Mana engine/combo piece)
• Tanazir Quandrix (Stat amplifier/win con)
• Staff of Domination (Combo enabler)
• Natural Order (Tutor for Tyrranax/win cons)
• Ozolith, the Shattered Spire (Counter preservation)
• Blade of Selves (Token cloning)
• Heroic Intervention (Board wipe protection)
• Toski, Bearer of Secrets (Card draw engine)
• Swiftfoot Boots (Commander protection)

Attribute Ratings:

Speed: 6/10
Can threaten lethal via combat by T7-8 with ideal draws or T5-6 with Natural Order -> Tyrranax. Infinite mana possible but lacks direct payoff.

Resilience: 5/10
Limited protection spells and heavy commander dependency make it vulnerable to targeted removal, though some recursion exists via Eternal Witness-like effects.

Consistency: 7/10
Strong card draw (11 sources) and tutors (Worldly/Natural Order) reliably find key pieces, but the 3+ card combos are fragile.

Interaction: 4/10
Minimal instant-speed answers (6 pieces) struggle against fast combo decks, though Counterspell and Krosan Grip handle critical threats.

Rating Justification:

The deck operates at optimized casual levels with T7-8 combat wins and a T6 ceiling via Natural Order, but its fragility to interaction and lack of compact combos prevent higher optimization. Resilience issues balance its decent speed and consistency.

Power level: 5.5 - 6.0
