Overview:

This Atraxa deck focuses on proliferating +1/+1 counters and level counters to rapidly scale threats, leveraging Atraxa's end-step proliferation to accelerate the strategy. The deck combines level-up creatures (e.g., Hexdrinker, Lighthouse Chronologist) with proliferate engines (e.g., Evolution Sage, Tekuthal, Inquiry Dominus) and counter doublers (Doubling Season, Lae'zel, Vlaakith's Champion). Atraxa serves as the core enabler, providing consistent proliferation and a resilient evasive threat. Win conditions involve overwhelming combat with hyper-scaled creatures, extra turns from Lighthouse Chronologist, or value locks via mass proliferation.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Deploy mana sources (e.g., Birds of Paradise, Nature's Lore) and low-level creatures (e.g., Student of Warfare, Enclave Cryptologist). Cast Atraxa by turn 4 using dual lands/fixers.
2. Counter Acceleration (Turns 4-6): Activate level-up abilities or deploy proliferate engines (Contagion Engine, Evolution Sage). Use Training Grounds to reduce level-up costs. Stack counters via Atraxa triggers and doublers.
3. Threat Deployment (Turns 5-7): Resolve high-impact payoffs like Kabira Vindicator (team buff), Lighthouse Chronologist (extra turns), or Transcendent Master (indestructible lifelinker). Equip Sword of Truth and Justice for combat proliferation.
4. Win Condition Execution:
   • Combat: Swing with leveled creatures (e.g., level 8+ Hexdrinker with protection from everything) backed by Time of Heroes/Brokers Ascendancy.
   • Extra Turns: Activate level 7+ Lighthouse Chronologist to chain turns.
   • Value Lock: Use The Ozolith to preserve counters after wipes and redeploy threats.

Mulligan Priorities:

• Keep hands with 2-3 lands including multicolor sources (e.g., Command Tower).
• Prioritize early ramp (Arcane Signet, Joraga Treespeaker) or a level-up creature + proliferate enabler.
• Include Atraxa protection (Lightning Greaves, Tamiyo's Safekeeping) or a counter doubler if possible.
• Avoid hands lacking early plays or color fixing.

Key Tips:

• Sequence Proliferation: Hold land drops for Evolution Sage triggers. Stack Atraxa's proliferate after combat to maximize counter placement.
• Protect Key Engines: Use Mutational Advantage/Heroic Intervention to shield creatures with counters from wipes. Fate Transfer can move counters to dodge removal.
• Maximize Doublers: Cast Lae'zel, Vlaakith's Champion before other counter sources. Doubling Season turns single proliferates into massive swings.
• Leverage Utility: Staff of Compleation offers removal, card draw, and proliferation. The Ozolith recovers counters after board wipes.

Weaknesses:

Critical

• Board Wipes: Farewell exiles counters and creatures, crippling recovery. Limited recursion beyond The Ozolith.
• Anti-Counter Hate: The One Ring/Solemnity nullifies the primary strategy. No answers in the list.
• Stax Pieces: Cursed Totem disables level-up abilities and mana dorks.

Moderate

• Graveyard Hate: Disrupts Bala Ged Recovery and The Ozolith's counter recovery.
• Fast Aggro: Slow setup leaves life total vulnerable to early pressure despite lifelink.

Minor

• Stack Interaction: Limited counterspells (only 4) struggle against noncreature combos.
• Artifact/Enchantment Removal: Key pieces like Doubling Season or Training Grounds are vulnerable.

Most Important Cards:

• Doubling Season (Doubles all counters, accelerates wins)
• Training Grounds (Enables cheap level-up activations)
• Lae'zel, Vlaakith's Champion (Counter doubler for permanents/players)
• Lighthouse Chronologist (Primary alternate win via extra turns)
• Evolution Sage (Landfall proliferate engine)
• Hexdrinker (Scalable threat with ultimate protection)
• The Ozolith (Counter preservation after wipes)
• Contagion Engine (Repeatable proliferation and soft removal)
• Brokers Ascendancy (Scales entire board passively)
• Sword of Truth and Justice (Combat-triggered proliferation)

Attribute Ratings:

Speed: 6/10

• Can threaten wins via combat or Lighthouse Chronologist by turns 7-9, but level-up costs and setup delay faster combos.

Resilience: 5/10

• Protection spells and The Ozolith mitigate some disruption, but heavy reliance on creatures and counters makes it vulnerable to targeted hate.

Consistency: 7/10

• Abundant proliferate sources and mana fixing ensure strategy execution, though tutors are limited to land fetching.

Interaction: 6/10

• Efficient targeted removal (Swords to Plowshares, Drown in Ichor) and counterspulls (Dovin's Veto, Negate), but lacks board wipes beyond Day of Judgment.

Rating Justification:

The deck executes a focused plan with strong synergy and high consistency, but its win speed (T7-9) and vulnerability to common disruption place it below optimized tiers. Resilience issues against hard counters and wipes cap its ceiling.

Power level: 6.0 - 6.5
