Overview:

Breya, Etherium Shaper is built as a synergistic artifact combo deck leveraging multiple infinite loops and efficient tutors. The core strategy focuses on generating artifact tokens (Thopters, Myr) to fuel Breya's abilities or assemble game-ending combos. Key win conditions include infinite mana/damage via Thopter Foundry/Sword of the Meek with Ashnod's Altar, extra turns with Time Sieve, and recursive value engines like Nim Deathmantle/Wurmcoil Engine. The deck balances artifact synergies, tutor density, and interaction while maintaining vulnerability to common artifact hate.

Primer:

Core Strategy: This deck aims to flood the board with artifacts, assemble infinite combos, or generate overwhelming value through Breya's sac outlets. The game plan progresses through three phases:

1. Artifact Acceleration: Deploy mana rocks (Sol Ring, Talisman of Progress), artifact lands, and token generators (Thopter Foundry, Myr Battlesphere) to enable early Breya casts and fuel sac outlets.
2. Combo Assembly: Tutor key pieces with Whir of Invention, Enlightened Tutor, and Tezzeret the Seeker. Prioritize infinite loops like Thopter Foundry/Sword of the Meek/Ashnod's Altar (infinite life/tokens/mana) or Nim Deathmantle/Ashnod's Altar/Wurmcoil Engine (infinite death triggers).
3. Win Execution: Convert infinite resources into victory via Breya's direct damage, Time Sieve extra turns, or combat with Cranial Plating-enhanced threats.

Mulligan Priorities:

• Keep hands with 3 lands (including artifact lands) and 2+ ramp artifacts.
• Prioritize early plays like Etherium Sculptor or Baleful Strix over slow value engines.
• Avoid hands without artifact synergy or combo potential.

Key Tips:

• Use Goblin Welder to recur combo pieces from the graveyard.
• Tezzeret, Master of the Bridge doubles as a finisher with his -8 ability.
• Protect critical artifacts with Academy Ruins recursion or Lightning Greaves.
• Time Sieve can win games with just 5 artifacts per turn - use Breya's token generation to enable it.

Avoid Traps:

• Don't overextend into board wipes before establishing recursion.
• Prioritize combo assembly over incremental value in high-power pods.
• Avoid keeping hands reliant on slow value engines like Sharding Sphinx.

Weaknesses:

Critical:

• Fold to artifact hosers like Stony Silence/Null Rod
• Graveyard hate disrupts Sword of the Meek/Myr Retriever loops

Moderate:

• Limited protection for combo pieces
• Relies on resolving key sorcery-speed tutors

Minor:

• Mana base vulnerable to Blood Moon effects
• Slow recovery from mass land destruction

Most Important Cards:

• Ashnod's Altar
• Thopter Foundry
• Sword of the Meek
• Time Sieve
• Nim Deathmantle
• Whir of Invention
• Urza, Lord High Artificer
• Tezzeret the Seeker
• Tezzeret, Master of the Bridge
• Phyrexian Metamorph

Attribute Ratings:

Speed: 7/10

• Can assemble T4-5 wins with ideal draws (T3 ramp into T4 combo)
• Average goldfish win by T6-7

Resilience: 6/10

• Multiple recursion engines (Academy Ruins, Goblin Welder)
• Vulnerable to targeted artifact hate and stack interaction

Consistency: 8/10

• 7+ tutors for combo pieces (Whir, Enlightened Tutor, Tezzeret)
• Redundant combo lines (Thopter/Sword vs Deathmantle/Ashnod)

Interaction: 6/10

• Targeted removal (Swords, Path, Vindicate)
• Lacks free counterspells for critical turns

Rating Justification:

This deck sits between "Focused Competitive" (7.0) and "Optimized" (6.5) on the rubric. It has:

• cEDH-adjacent combos but lacks free interaction/protection
• T5-6 deterministic wins vs T5-6 goldfish benchmarks
• Tutor density comparable to 6.5-7.0 decks but weaker stax resilience

Power level: 6.5 - 7.0
