Overview:

This Breya, Etherium Shaper deck is a high-synergy artifact combo engine that leverages recursive loops, infinite mana generation, and value engines to establish dominant board states or win outright. Breya serves as both a combo piece (sac outlet for artifact tokens) and removal engine, but the deck's true power lies in its dense network of artifact synergies and multiple A+B combos. Key themes include artifact recursion (Goblin Welder, Emry, Lurker of the Loch), cost reduction (Etherium Sculptor, Foundry Inspector), and explosive mana generation (Krark-Clan Ironworks, Ashnod's Altar).

Primer:

Core Strategy Execution:

1. Early Setup (T1-3): Deploy artifact mana (Sol Ring, Talisman of Dominance, artifact lands) and value engines like Esper Sentinel/Rhystic Study. Use tutors (Demonic Tutor, Fabricate) to find combo pieces or protection.
2. Mid-Game Engine (T3-5): Cast Breya to generate Thopters, then leverage artifact synergies with Sai, Master Thopterist or Jhoira, Weatherlight Captain. Deploy combo enablers like Displacer Kitten (blinking value artifacts) or Unwinding Clock.
3. Win Conditions (T4-7):
   • Infinite Mana Combos:
     • Worldgorger Dragon + Animate Dead (infinite ETB/LTB triggers) with any mana rock → infinite colored mana → Breya burn
     • Krark-Clan Ironworks + Thopter Foundry + Sword of the Meek (infinite tokens/mana)
   • Direct Wins:
     • Time Sieve + 5 artifacts per turn (extra turns)
     • Marionette Master + mass artifact sacrifice
     • Urza, Lord High Artificer infinite mana → deck manipulation → Walking Ballista

Mulligan Priorities:

• Keep hands with 2-3 lands including artifact lands
• Prioritize early ramp (Sol Ring, Arcane Signet) + at least 1 tutor or card filterer (Sensei's Divining Top, Mystic Remora)
• Combo hands with 2+ pieces (e.g., Thopter Foundry + Sword of the Meek + sac outlet) are keepable with protection

Key Tips:

• Use Goblin Engineer/Buried Ruin to recur combo pieces like Sword of the Meek
• Teferi's Protection protects against board wipes during combo setup
• Displacer Kitten can reset Solemn Simulacrum-style effects or dodge removal on key pieces
• Mystic Forge enables top-deck manipulation for critical combo pieces

Weaknesses:

Critical

• Graveyard hate (Rest in Peace, Leyline of the Void) shuts off Worldgorger/Animate Dead, Thopter recursion, and artifact retrieval
• Stony Silence/Null Rod cripples artifact mana and combo engines
• Fast aggro can pressure life total before combos assemble

Moderate

• Collector Ouphe/Karn, the Great Creator disrupts artifact synergies
• Drannith Magistrate/Lavinia, Azorius Renegade blocks key cast-from-graveyard/cheat effects
• Stack interaction targeting combo payoffs (e.g., countering Breya after infinite mana is generated)

Minor

• Single-target artifact removal (deck has multiple recursion options)
• Blood Moon effects (minimal basic land count, but many artifact mana sources)

Most Important Cards:

• Worldgorger Dragon (Infinite mana combo linchpin)
• Thopter Foundry (Combo engine with Sword of the Meek)
• Krark-Clan Ironworks (Mana amplification/sac outlet)
• Demonic Tutor (Tutoring critical combo pieces)
• Teferi's Protection (Combo turn protection)
• Displacer Kitten (Value engine/combo enabler)
• Urza, Lord High Artificer (Mana generation/win condition)
• Animate Dead (Worldgorger enabler)
• Time Sieve (Alternative win condition)
• Goblin Engineer (Graveyard setup/recursion)

Attribute Ratings:

Speed: 8/10

• Capable of T3-4 wins with perfect hands (Worldgorger/Animate Dead + mana rock), typically threatens wins by T5-6 through multiple redundant combos.

Resilience: 6/10

• Multiple recursion engines and protection spells (Dovin's Veto, Teferi's Protection), but core combos remain vulnerable to well-timed interaction.

Consistency: 8/10

• 12 tutors, 8 card draw engines, and heavy artifact redundancy ensure frequent access to combo pieces.

Interaction: 7/10

• Robust suite of counterspells (Mana Drain, Fierce Guardianship), targeted removal (Swords to Plowshares), and board wipes (Toxic Deluge).

Rating Justification:

This deck operates at cEDH-adjacent speeds with T3-4 win potential through compact combos and premium tutors, but lacks the layered protection and free interaction of top-tier lists. Its resilience against stax is hampered by critical artifact dependencies, placing it just below top competitive tiers.

Power level: 7.5 - 8.0
