Overview:

This Breya, Etherium Shaper deck is a synergistic artifact combo/control build leveraging Breya’s flexible removal abilities and Thopter generation. The primary strategy revolves around artifact token spam, infinite loops, and value engines to enable wins through combat, combo, or stax-like locks. Breya serves as a recursive removal tool and combo enabler, but the deck can function independently with "hidden commanders" like Urza, Lord High Artificer and Tezzeret the Seeker. Key themes include artifact cost reduction, token generation, and graveyard recursion.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy artifact ramp (Sol Ring, Izzet Signet, Etherium Sculptor), set up draw engines (Esper Sentinel, Jhoira, Weatherlight Captain), and establish token generators (Sai, Master Thopterist, Thopter Foundry).
2. Midgame Value (Turns 4-6): Resolve combo enablers (Ashnod’s Altar, Time Sieve, Nim Deathmantle) or synergistic threats (Urza, Lord High Artificer, Sharding Sphinx). Use Breya’s removal to disrupt opponents.
3. Win Conditions:
   • Infinite Combos:
     • Ashnod’s Altar + Nim Deathmantle + Breya: Sacrifice Breya and two Thopters to Altar for 4 mana, pay 4 via Deathmantle to recur Breya, netting infinite death/ETB triggers and mana.
     • Time Sieve + 5 artifact tokens per turn (via Thopter Foundry, Sai, etc.): Take infinite turns.
   • Combat Overload: Overwhelm with Thopters boosted by Master of Etherium, Cranial Plating, or Cyberdrive Awakener.
   • Alternate Wins: Mechanized Production on a token generator or Mirrodin Besieged (Phyrexian mode).

Mulligan Priorities:

• Keep hands with 2-3 lands (including artifact lands) and early ramp/draw.
• Prioritize combo pieces (Altar, Time Sieve) if interaction is light.
• Avoid hands without artifact synergy or color fixing.

Key Tips:

• Use Eldrazi Displacer to flicker Breya for repeated removal or token generation.
• Whir of Invention and Fabricate fetch critical artifacts like Time Sieve or protection (Padeem, Consul of Innovation).
• Sacrifice tokens to Thopter Foundry for life gain and blockers while building toward combos.

Weaknesses:

Critical

• Artifact Hate: Stony Silence, Null Rod, or Collector Ouphe cripple mana, combos, and value engines.
• Graveyard Exile: Disrupts recursion via Emry, Lurker of the Loch, Daretti, Scrap Savant, and Myr Retriever.
• Fast Aggro: Struggles to stabilize against early creature swarms before combos assemble.

Moderate

• Board Wipes: Farewell or Cyclonic Rift reset token boards; recovery relies on recursion.
• Countermagic: Key combo pieces (Time Sieve, Altar) are vulnerable to counterspells.

Minor

• Mana Base Fragility: Relies on artifact lands vulnerable to Vandalblast; color requirements strain fixing.

Most Important Cards:

• Ashnod’s Altar (Combo enabler, mana acceleration)
• Time Sieve (Infinite turns wincon)
• Urza, Lord High Artificer (Mana generation, card advantage)
• Nim Deathmantle (Recursion/combo piece)
• Tezzeret the Seeker (Tutor, artifact synergy)
• Whir of Invention (Tutor for critical artifacts)
• Jhoira, Weatherlight Captain (Card draw engine)
• Thopter Foundry (Token generation, lifegain, combo fuel)
• Eldrazi Displacer (Utility, combo support)
• Mechanized Production (Alternate wincon)

Attribute Ratings:

Speed: 6/10

• Can threaten infinite turns or combo kills by T6-7 with ideal draws, but relies on setup for most lines.

Resilience: 5/10

• Limited protection outside Padeem; combos are fragile to interaction. Recursion helps but is slow.

Consistency: 7/10

• Strong tutoring (Whir, Fabricate, Tezzeret) and card draw (Jhoira, Thought Monitor) ensure access to key pieces.

Interaction: 6/10

• Targeted removal (Breya, Anguished Unmaking, Swords to Plowshares) and counterspulls (Counterspell) are present but not exhaustive.

Rating Justification:

This deck operates at a 6.0 - 6.5 power level, capable of T6-7 combo wins with tutors and redundancy but held back by vulnerability to artifact hate and slower interaction. Its resilience and meta-dependent speed align with "Focused" tiers, outperforming casual builds but lacking the protection and speed of cEDH.

Power level: 6.0 - 6.5
