Overview:

This Zinnia, Valley's Voice deck combines token generation through Zinnia's offspring ability and ETB-based damage/lifegain synergies, with a secondary combo finish using Thassa's Oracle and Enter the Infinite. The deck leverages fast mana, tutors, and protective interaction to assemble either a critical mass of creature ETBs or a deterministic draw-engine win.

Primer:

Core Strategy:
Deploy 1-power creatures and token generators to trigger Zinnia's power boost while generating value from ETB effects like Impact Tremors and Auriok Champion. Secondary wincons include:

1. Oracle Combo: Tutor for Enter the Infinite (via Solve the Equation/Mystical Tutor), cast it with fast mana, then win with Thassa's Oracle.
2. Aetherflux Storm: Chain creature spells with offspring triggers and Panharmonicon to gain massive life, then fire Aetherflux Reservoir.
3. Aggro-Ping: Overwhelm with Witty Roastmaster and Agate Instigator triggers amplified by token armies.

Mulligan Priorities:

• Keep hands with 2+ mana accelerants (Mana Vault, Sol Ring).
• Prioritize early ETB engines (Soul Warden, Esper Sentinel).
• Reject hands lacking creature density or protection in interactive metas.

Key Tips:

• Use Grand Abolisher or Silence before casting Enter the Infinite.
• Panharmonicon doubles both token copies and ETB triggers.
• Urza's Saga fetches critical 1-mana artifacts (Mox Amber, Sensei's Divining Top).

Weaknesses:

Critical

• Relies on resolving high-CMC sorceries (Enter the Infinite) vulnerable to counterspells.
• Limited graveyard recursion for combo pieces.

Moderate

• Board wipes disrupt token/ETB synergies despite Teferi's Protection.
• Requires Zinnia to maximize token generation efficiency.

Minor

• Some tapped lands slow early sequencing.

Most Important Cards:

• Thassa's Oracle
• Enter the Infinite
• Aetherflux Reservoir
• Panharmonicon
• Grand Arbiter Augustin IV
• Smothering Tithe
• Rhystic Study
• Impact Tremors
• Urza's Saga
• Grand Abolisher

Attribute Ratings:

Speed: 7/10
Theoretical T5-6 Oracle combo with perfect fast mana, but typically closes via ETB ping or Reservoir around T7-8.

Resilience: 7/10
Free counterspells (Force of Will, Fierce Guardianship) and stax pieces (Grand Abolisher) protect key turns.

Consistency: 7/10
10+ tutors and card draw engines (Rhystic Study, Mystic Remora) reliably find combo pieces or synergy drivers.

Interaction: 8/10
S-tier counterspells and targeted removal (Path to Exile, Cyclonic Rift) handle most threats.

Rating Justification:

This deck operates at the high end of optimized casual play, combining multiple A/B-tier wincons with cEDH-level interaction but held back by its reliance on a 12-mana sorcery as a primary combo piece.

Power level: 6.5 - 7.0
