Overview:

This Breya, Etherium Shaper deck is a high-synergy artifact combo engine leveraging Breya's ability to convert artifact tokens into removal, lifegain, or direct damage. The strategy revolves around assembling infinite loops using artifacts like Thopter Foundry/Sword of the Meek, Krark-Clan Ironworks/Time Sieve, and Worldgorger Dragon/Animate Dead, supported by tutors, recursion, and explosive mana generation. Breya acts as both a combo finisher and value engine, enabling instant-speed interaction via Liberator, Urza's Battlethopter flash synergies and Displacer Kitten flicker chains.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy mana rocks (Sol Ring, Talisman of Progress), artifact lands, and value engines like Esper Sentinel or Rhystic Study. Use Urza's Saga to fetch key 0-1 MV artifacts (e.g., Skullclamp).
2. Combo Assembly (Turns 3-5): Tutor for Thopter Foundry/Sword of the Meek via Goblin Engineer or Fabricate. Pair with Krark-Clan Ironworks or Ashnod's Altar to generate infinite tokens/mana. Alternatively, cheat Worldgorger Dragon into play with Animate Dead for infinite ETB/LTB triggers.
3. Win Conditions:
   • Infinite Thopters + Breya: Sac tokens to Breya's -4/-4 or 3-damage ability to eliminate opponents.
   • Time Sieve + Infinite Artifacts: Take infinite turns.
   • Marionette Master + Mass Sacrifice: Drain opponents via artifact deaths.
   • Tezzeret, Master of the Bridge: Burn opponents with artifact count.

Mulligan Priorities:

• Keep hands with 2-3 lands (including artifact lands), 1-2 ramp pieces, and at least one tutor or combo component.
• Prioritize Liberator, Urza's Battlethopter or Displacer Kitten for flash/flicker synergies.
• Avoid hands lacking early artifacts or color fixing.

Key Tips:

• Use Goblin Welder/Emry, Lurker of the Loch to recur combo pieces from the graveyard.
• Displacer Kitten flickers Breya to reset her abilities or dodge removal while triggering artifact ETBs.
• Teferi's Protection protects against board wipes during combo setup.

Weaknesses:

Critical

• Graveyard hate (Rest in Peace, Leyline of the Void) cripples Worldgorger Dragon, Animate Dead, and recursion engines.
• Artifact board wipes (Vandalblast, Farewell) disrupt mana base and combo pieces.
• Anti-synergy stax (Null Rod, Stony Silence) shuts down artifact activations.

Moderate

• Countermagic targeting combo enablers like Krark-Clan Ironworks or Thopter Foundry.
• Drannith Magistrate/Aven Mindcensor disrupts tutor-heavy strategy.

Minor

• Spot removal on Breya delays the game plan but doesn’t cripple the deck.
• Limited basic lands make the mana base vulnerable to Blood Moon.

Most Important Cards:

• Thopter Foundry (Core combo piece for infinite tokens/life)
• Krark-Clan Ironworks (Mana engine/combo enabler)
• Worldgorger Dragon (Infinite mana/ETB loop with Animate Dead)
• Liberator, Urza's Battlethopter (Flash synergy, protects combos)
• Displacer Kitten (Flickers Breya/artifacts for value and protection)
• Demonic Tutor/Vampiric Tutor (Finds critical combo pieces)
• Teferi's Protection (Protects against board wipes during setup)
• Goblin Engineer (Recurs combo pieces from graveyard)
• Time Sieve (Infinite turns with sufficient artifacts)
• Urza, Lord High Artificer (Mana generation and Construct synergy)

Attribute Ratings:

Speed: 8/10
Capable of T3-4 wins with ideal draws (e.g., T1 Sol Ring → T2 Krark-Clan Ironworks → T3 Thopter Foundry/Sword of the Meek).

Resilience: 6/10
Multiple recursion engines (Academy Ruins, Goblin Welder) and protection (Teferi's Protection, counterspells), but combos are vulnerable to common interaction.

Consistency: 8/10
12 tutors (e.g., Demonic Tutor, Whir of Invention) and robust card draw (Rhystic Study, Jhoira, Weatherlight Captain) ensure reliable access to combo pieces.

Interaction: 7/10
Efficient removal (Swords to Plowshares, Cyclonic Rift), counterspells (Mana Drain, Dovin's Veto), and stax (Ethersworn Canonist).

Rating Justification:

This deck operates at cEDH-adjacent speeds (T3-4 win potential) with redundant combos and top-tier tutors but lacks the stack interaction and resilience of top-tier lists. Its reliance on artifacts and graveyard makes it vulnerable to common meta answers, placing it just below cEDH viability.

Power level: 7.5 - 8.0
