Overview:

This five-color Myr tribal deck leverages Urtet's token generation and untap synergy to rapidly build a wide board of artifact creatures. The primary win conditions involve infinite mana combos utilizing Myr untappers (e.g., Myr Galvanizer), token generators (Myr Turbine), and payoff cards like Walking Ballista. Secondary strategies include stax locks (Winter Orb + Clock of Omens) and overwhelming combat with pumped Myrs. Urtet acts as both an engine (untapping Myr for mana/abilities) and a finisher (mass +1/+1 counters), though the deck heavily relies on artifact synergies and combos independent of the commander.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-3): Deploy mana accelerants (Sol Ring, Mana Vault, mana Myrs) and value engines (Rhystic Study, Mystic Remora). Prioritize fixing for Urtet's WUBRG cost.
2. Board Development (Turns 3-5): Cast Urtet and Myr token generators (Myr Turbine, Myr Matrix). Use tutors (Demonic Tutor, Fabricate) to find combo pieces or stax elements. Leverage card draw (The One Ring, Thoughtcast) to dig.
3. Combo/Lock Assembly (Turns 4-7):
   • Infinite Mana: Myr Galvanizer + Palladium Myr/Iron Myr + Intruder Alarm/Mana Echoes → Fuel Walking Ballista or Rocket Launcher.
   • Stax Lock: Winter Orb/Static Orb + Clock of Omens/Intruder Alarm to paralyze opponents.
   • Combat: Activate Urtet's WUBRG ability with a wide board for lethal swings.
4. Win Execution: Tutor/draw into payoff; deploy Ballista/Rocket Launcher or swing with massive Myrs.

Mulligan Priorities:

• Keep hands with 2-3 lands (including fixing), 1-2 ramp pieces, and either a combo piece, tutor, or card draw engine.
• Prioritize hands enabling T3-4 Urtet. Avoid hands lacking colored sources or early plays.
• Hands with protection (Defense Grid, counterspells) are stronger against interaction.

Key Tips:

• Untap Synergy: Urtet's combat trigger enables explosive turns with mana Myrs or Myr Galvanizer. Pair with Intruder Alarm for instant-speed combos.
• Protection is Critical: Use counterspells (Swan Song, Counterspell) and Defense Grid to shield combos. Academy Ruins recurs key artifacts.
• Leverage Tutors: Kuldotha Forgemaster and transmute (Muddle the Mixture) fetch combo/stax pieces. Tezzeret, Master of the Bridge doubles as a finisher.
• Stax Pivots: If combos are disrupted, lock opponents with Stasis + Clock of Omens or Opposition/Glare of Subdual.

Weaknesses:

Critical

• Commander-dependent: Urtet removal cripples untap synergy and delays the WUBRG finisher ability.
• Severe vulnerability to artifact sweepers (Vandalblast, Farewell) and anti-ability stax (Cursed Totem, Karn, the Great Creator).
• Null Rod/Collector Ouphe shuts down mana rocks, Myr mana abilities, and combo payoffs.

Moderate

• Graveyard hate (Rest in Peace) disrupts recursion (Myr Retriever, Academy Ruins).
• Board wipes reset Myr tokens, slowing the primary engine.
• Limited stack interaction for non-creature threats beyond counterspells.

Minor

• High color requirements can strain mana fixing if key lands are destroyed.
• Some combo lines require multiple pieces vulnerable to spot removal.

Most Important Cards:

• Myr Galvanizer (Core combo enabler: untaps Myr for infinite mana)
• Intruder Alarm (Untaps Myr with token generation, enables instant-speed combos)
• Ashnod's Altar (Mana acceleration/sac outlet for combos and value)
• Walking Ballista (Primary infinite mana payoff)
• Myr Turbine (Token generation engine, tutors key Myr)
• Clock of Omens (Untaps stax pieces/combo artifacts)
• Demonic Tutor (Fetches any combo/stax/protection piece)
• Mana Vault (Explosive early ramp enabling T3 Urtet)
• Winter Orb (Stax piece that locks opponents with untap synergy)
• Rhystic Study (Critical card draw to find pieces)

Attribute Ratings:

Speed: 8/10

• Capable of T4-5 wins with ideal draws (e.g., T1 Vault → T2 Turbine → T3 Urtet + Galvanizer → T4 win). Average goldfish win ~T6.

Resilience: 5/10

• Multiple tutors and draw engines provide redundancy, but core combos are fragile to targeted removal. Recursion (Academy Ruins) and counterspells offer mitigation, but board wipes/stax hosers are devastating.

Consistency: 7/10

• 10+ tutors, strong card draw (Rhystic, Remora, Ponder), and functional redundancy in combo pieces ensure reliable access to win conditions.

Interaction: 6/10

• Efficient counterspells (Swan Song, Counterspell) and stax (Orbs, Opposition) disrupt opponents, but lacks broad permanent removal and struggles against resolved non-creature haymakers.

Rating Justification:

This deck operates at high-power levels with T4-5 win potential through efficient artifact-based combos and tutors, aligning with the "Focused Competitive" tier. However, its vulnerability to common disruption (artifact removal, commander targeting) and reliance on Urtet for maximum efficiency prevent it from reaching cEDH viability. Resilience limitations temper its speed.

Power level: 7.0 - 7.5
