Overview:

This 5-color Dragon tribal deck leverages The Ur-Dragon's eminence ability to rapidly deploy an aerial assault of high-impact Dragons. The strategy focuses on cost reduction (Urza's Incubator, Ruby Medallion, Sarkhan, Soul Aflame) to flood the board with evasive threats, supported by explosive card draw from attack triggers and value engines like The Great Henge. Win conditions center on overwhelming combat damage amplified by synergy pieces like Atarka, World Render (double strike enabler) and Scourge of the Throne (extra combats), with backup plans via direct damage from Terror of the Peaks/Dragon Tempest and artifact theft with Hellkite Tyrant. The Ur-Dragon acts as both a cost reducer and late-game finisher, but the deck can operate effectively without it.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4):
   • Deploy mana rocks (Sol Ring, Arcane Signet), land-based ramp (Farseek, Three Visits), and cost reducers (Urza's Incubator, Ruby Medallion).
   • Establish card advantage engines: Rhystic Study, Sylvan Library, or Up the Beanstalk.

2. Midgame Threats (Turns 4-6):

   • Cast discounted Dragons with immediate impact: Miirym, Sentinel Wyrm (token doubling), Goldspan Dragon (Treasure generation), or Ancient Copper Dragon (mana explosion).
   • Use Sneak Attack or Hellkite Courser for surprise threats.

3. Combat Dominance (Turns 5-8):

   • Activate Aggravated Assault with Savage Ventmaw for infinite combats.
   • Deploy game-ending synergy: Scourge of Valkas + token Dragons, Wrathful Red Dragon + Blasphemous Act, or Atarka, World Render with trample enablers.

Mulligan Priorities:

• Keep hands with 2-3 lands including at least one green source.
• Prioritize early ramp (mana rocks, Sarkhan, Fireblood) and at least one Dragon payoff.
• Value hands with Cavern of Souls or Steely Resolve against control matchups.

Key Tips:

• Use Phyrexian Reclamation/Volrath's Stronghold to recur key Dragons like Terror of the Peaks.
• Cyclonic Rift often wins games when paired with a developed Dragon board.
• Roaming Throne (naming Dragon) doubles all attack/ETB triggers.

Weaknesses:

Critical

• Vulnerable to early stax pieces like Cursed Totem (shuts off mana rocks and Sarkhan, Fireblood) and Damping Sphere (punishes mana acceleration).
• Struggles against Humility-style effects that negate Dragon abilities.

Moderate

• Board wipes bypass Steely Resolve protection and delay the combat plan.
• Graveyard hate disrupts Phyrexian Reclamation/Volrath's Stronghold recursion lines.

Minor

• Limited stack interaction for protecting combats (only Teferi's Protection as a panic button).
• High mana value spells can lead to clunky hands without sufficient ramp.

Most Important Cards:

• The Ur-Dragon (Cost reduction engine and card advantage)
• Miirym, Sentinel Wyrm (Token duplication for exponential Dragon value)
• Sneak Attack (Cheats in game-ending Dragons for immediate impact)
• Terror of the Peaks (Direct damage enabler)
• Aggravated Assault (Infinite combat enabler with Ventmaw)
• Cyclonic Rift (Board reset that preserves your flying threats)
• Cavern of Souls (Ensures uncounterable Dragons)
• Rhystic Study (Critical early card advantage)
• Urza's Incubator (Essential cost reduction)
• Scourge of the Throne (Combat phase multiplier)

Attribute Ratings:

Speed: 7/10
Can deploy lethal boards by turn 6-7 through cost reduction and cheat effects, with occasional explosive starts via Sneak Attack + Hellkite Courser.

Resilience: 6/10
Multiple recursion engines and protection like Steely Resolve, but heavily reliant on maintaining a critical mass of Dragons.

Consistency: 8/10
12 tutors (including Imperial Seal, Worldly Tutor), strong card draw, and redundant cost reducers ensure key pieces are accessible.

Interaction: 5/10
Spot removal (Assassin's Trophy) and a board wipe suite, but limited counterspells and reactive protection.

Rating Justification:

This deck demonstrates optimized tribal synergy with cEDH-grade mana/tutors, capable of threatening T6-7 wins through combat or combo lines. While lacking the instant-speed interaction and compact wincons of true cEDH decks, it exceeds casual power ceilings through efficiency and redundancy.

Power level: 6.5 - 7.0
