Overview:

This Ur-Dragon deck leverages cost reduction and tribal synergy to flood the board with Dragons, generating overwhelming value through attack triggers and combat damage. While lacking infinite combos, it employs high-impact synergies like Miirym, Sentinel Wyrm token duplication and Scourge of Valkas burn effects to dominate mid-late game boards.

Primer:

Core Strategy:
Deploy cost-reduced Dragons early via The Ur-Dragon's Eminence and reducers (Dragonspeaker Shaman, Herald's Horn), then snowball with attack-triggered card advantage and token generation. Win through combat overruns enhanced by Thrakkus the Butcher power doubling and Aggravated Assault extra combats. Key payoffs like Utvara Hellkite and Ancient Gold Dragon exponentially increase board presence.

Mulligan Priorities:

• 3+ lands with color diversity
• 1-2 mana accelerants (Birds of Paradise, Bloom Tender)
• Early Dragon reducers (Dragonlord's Servant, Sarkhan, Soul Aflame)
  Reject hands without ramp or color fixing.

Key Lines:

1. T1-T3: Ramp + cost reducers
2. T4+: Cast 2-3 Dragons per turn via Ur-Dragon discounts
3. Attack triggers draw into more Dragons/permanents via Ur-Dragon
4. Finish with Scourge of the Throne combats or Dragon Tempest burn

Protection Essentials:
Use Lightning Greaves on key Dragons, hold Boros Charm for board wipe protection, and deploy Rootborn Defenses against mass removal.

Weaknesses:

Moderate:

• Vulnerable to early stax (Blood Moon, Back to Basics) disrupting 5-color mana
• Limited recovery from multiple board wipes
• No infinite combos for instant-speed wins

Minor:

• High CMC threats susceptible to targeted removal
• Relies on combat damage without alternate wincons

Most Important Cards:

• Miirym, Sentinel Wyrm
• Tiamat
• Ancient Gold Dragon
• Aggravated Assault
• Dragon Tempest
• Utvara Hellkite
• Scourge of Valkas
• Morophon, the Boundless
• Fist of Suns
• Eerie Ultimatum

Attribute Ratings:

Speed: 6/10
Cost reduction enables 5-7 mana Dragons by T3-4. Goldfish kills achievable by T8 via combat chains.

Resilience: 5/10
Moderate recursion (Eerie Ultimatum, Bladewing the Risen), but key pieces lack protection beyond 1-2 combat tricks.

Consistency: 7/10
11+ Dragon cost reducers, 5 tutors (Eladamri's Call, Sarkhan's Triumph), and Ur-Dragon's card draw ensure tribal synergy.

Interaction: 4/10
Limited to spot removal (Swords to Plowshares, Counterspell) and reactive protection. No free spells or stax.

Rating Justification:

This deck exceeds optimized casual (5.0) through strong tribal synergy and explosive combat turns but lacks the speed (T7-8 vs T6-7) and interaction density of focused competitive lists. Its reliance on combat damage and midrange value aligns with the 6.0 "Focused" tier that wins via overwhelming board states by T7-8. The absence of infinite combos and lower interaction density prevent higher ratings.

Power level: 5.5 - 6.0
