Overview:

Breya, Etherium Shaper pilots a high-synergy artifact combo deck leveraging flicker effects, infinite mana loops, and explosive value engines. The deck combines fast artifact ramp, efficient tutors, and multiple layers of protection to assemble game-ending combos like Ashnod's Altar + Nim Deathmantle or Deadeye Navigator synergies. While not cEDH-optimized, it operates at a focused power level with consistent T6-7 wins through disruption.

Primer:

Core Strategy:
This deck aims to flood the board with artifacts, generate infinite mana via Ashnod's Altar/Eldrazi Displacer loops, and convert it into lethal damage through Breya's abilities. Secondary lines include Urza, Lord High Artificer constructs, Marionette Apprentice death triggers, and overwhelming value from The One Ring/Rhystic Study. Flicker effects like Displacer Kitten protect key pieces while generating ETB value.

Key Combos:

1. Infinite Mana/Thopters: Ashnod's Altar + Nim Deathmantle + any creature that creates 2+ tokens on death (Breya herself provides fuel).
2. Deadeye Lock: Deadeye Navigator + Reckless Fireweaver for infinite damage or Baleful Strix for infinite draw.
3. Urza Dominance: Urza, Lord High Artificer + Eldrazi Displacer to generate infinite colorless mana and massive constructs.

Mulligan Priorities:

• Keep hands with 2 lands + artifact ramp (Sol Ring, Arcane Signet).
• Prioritize T1-T2 plays enabling T3 Breya.
• Reject hands without artifact synergy or protection.

Critical Interactions:

• Displacer Kitten blinks Breya to reset her artifact sacrifice abilities.
• Agatha's Soul Cauldron steals key abilities from exiled combo pieces.
• Lotho, Corrupt Shirriff converts opponents' spellcasting into Treasure for combo fuel.

Win Conversion:
Infinite mana feeds Breya's damage ability, Marionette Apprentice life loss, or Bolas's Citadel storm turns. Backup plans include Mondrak, Glory Dominus token floods and Cyclonic Rift into alpha strikes.

Weaknesses:

Critical:

• Folded by Stony Silence/Null Rod shutting off artifact synergies.
• Rest in Peace disrupts Animate Dead/graveyard recursion lines.

Moderate:

• Relies on 3-4 key artifacts for infinite combos.
• Limited answers to resolved enchantments.

Minor:

• Recovers well from single-target removal via flicker effects.

Most Important Cards:

• Ashnod's Altar
• Nim Deathmantle
• Urza, Lord High Artificer
• The One Ring
• Demonic Tutor
• Eldrazi Displacer
• Deadeye Navigator
• Rhystic Study
• Fierce Guardianship
• Smothering Tithe

Attribute Ratings:

Speed: 7/10
Goldfishes T5-6 wins through infinite mana combos. Fast mana (Lotus Petal, Sol Ring) enables explosive starts, but lacks cEDH-level acceleration.

Resilience: 7/10
9x protection spells (Fierce Guardianship, Teferi's Protection) and 6x flicker effects provide layered defense. Weak to artifact-specific hate.

Consistency: 8/10
11x tutors (Vampiric Tutor, Imperial Recruiter) and 8x draw engines ensure combo assembly. Redundant combo pieces (3+ infinite mana sources).

Interaction: 7/10
S-Tier counterspells (Swan Song, Flusterstorm) and board wipes (Toxic Deluge). Limited permanent removal for resolved threats.

Rating Justification:

This deck operates between Rubric 6.5-7.0:

• Speed matches "Optimized" T6-7 benchmarks
• Resilience surpasses typical "Focused" decks through protection density
• Tutor density and combo redundancy exceed "Focused" but lack cEDH's T3 win consistency
• Interaction suite is stronger than average "Focused Competitive" but lacks free artifact removal

Power level: 6.5 - 7.0
