Overview:

This 5-color Dragon tribal deck leverages The Ur-Dragon's eminence ability to deploy massive flying threats ahead of curve while generating immense value through attack triggers. The primary strategy involves explosive ramp into game-ending Dragon boards, amplified by multiple combat enablers, ETB damage triggers, and free permanent deployment. The Ur-Dragon serves as both a cost reducer and critical value engine, enabling card draw and battlefield cheating whenever Dragons attack. Secondary win conditions include infinite combat steps with Savage Ventmaw/Aggravated Assault, Hellkite Tyrant artifact theft, and overwhelming damage from Terror of the Peaks/Dragon Tempest triggers.

Primer:

Core Strategy Execution:

1. Early Ramp (Turns 1-3): Deploy Sol Ring, Arcane Signet, Farseek, or fetch lands to fix colors. Use Urza's Incubator and Ruby Medallion to amplify cost reduction alongside The Ur-Dragon's eminence.
2. Mid-Game Threats (Turns 4-6): Cast key Dragons like Miirym, Sentinel Wyrm (doubling Dragon ETBs), Ancient Copper Dragon (Treasure generation), or Scourge of the Throne (extra combats). Activate Sarkhan, Fireblood for Dragon-specific ramp.
3. Combo/Lock Setup: Pair Savage Ventmaw with Aggravated Assault for infinite combat phases. Use Hellkite Courser to cheat The Ur-Dragon into play for immediate value.
4. Endgame Overrun: Deploy The Great Henge and Rhystic Study for sustained value. Close with Balefire Dragon board wipes, Atarka, World Render double-strike enablers, or Call the Spirit Dragons alt-win condition.

Mulligan Priorities:

• Keep hands with 3+ lands including color fixing (fetch/shock lands).
• Prioritize 1-2 ramp pieces and at least one Dragon cost reducer (Ur-Dragon eminence + Urza's Incubator/Sarkhan, Fireblood).
• Mulligan away high-CMC clumps without ramp.

Key Tips:

• Use Cavern of Souls and Steely Resolve to protect key Dragons from counterspells.
• Phyrexian Reclamation and Volrath's Stronghold enable graveyard recursion for combo pieces.
• Cyclonic Rift and Teferi's Protection protect against board wipes during critical turns.

Weaknesses:

Critical

• Extreme vulnerability to Cursed Totem/Linvala, Keeper of Silence shutting off Dragon ETB/attack triggers and mana abilities.
• Heavy reliance on 5+ CMC creatures makes recovery from board wipes like Farewell difficult.

Moderate

• Drannith Magistrate/Lavinia, Azorius Renegade can block free permanent deployment from The Ur-Dragon's attack trigger.
• Artifact hate disrupts critical ramp (The Great Henge, Dragon's Hoard) and combo pieces (Aggravated Assault).

Minor

• Limited stack interaction beyond Assassin's Trophy and Cyclonic Rift.
• High life payment from shock/fetch lands can be exploited by aggressive decks.

Most Important Cards:

• The Ur-Dragon (Cost reduction engine and value generator)
• Miirym, Sentinel Wyrm (Double Dragon ETBs for exponential value)
• Aggravated Assault (Infinite combat enabler with Savage Ventmaw)
• Terror of the Peaks (Burn engine for Dragon deployments)
• Ancient Copper Dragon (Mass Treasure generation)
• Savage Ventmaw (Mana battery for combat loops)
• The Great Henge (Card draw and counters)
• Rhystic Study (Continuous card advantage)
• Cavern of Souls (Dragon protection and fixing)
• Cyclonic Rift (Board reset protection)

Attribute Ratings:

Speed: 8/10
Capable of T4-T5 wins with ideal ramp into Miirym + Dragon swarm or T6 infinite combats. Eminence cost reduction enables consistent early Dragon deployment.

Resilience: 6/10
Multiple protection spells (Teferi's Protection, Steely Resolve) and recursion tools, but high CMC creatures make rebuilds slow after wipes.

Consistency: 9/10
12 tutors (including Demonic Tutor, Worldly Tutor), 8+ card draw engines, and 15 ramp pieces ensure reliable access to key components.

Interaction: 5/10
Limited removal suite focused on artifacts/enchantments (Assassin's Trophy, Boseiju), with Cyclonic Rift as the only board reset.

Rating Justification:

This deck operates at cEDH-adjacent speed with T5-6 win potential through combat loops and Dragon swarms, supported by top-tier tutors and ramp. However, its vulnerability to stax pieces and reliance on combat damage (vs. compact combos) place it just below top-tier competitive decks.

Power level: 7.5 - 8.0
