Overview:

This 5-color Dragon tribal deck leverages The Ur-Dragon's eminence ability to reduce Dragon costs and generate massive value through combat triggers. The primary strategy focuses on explosive ramp (fast mana artifacts, dorks, and rituals) to deploy high-impact Dragons early, then snowball through card advantage and cheat effects like Sneak Attack and Hellkite Courser. The Ur-Dragon acts as both a cost reducer and a late-game engine, enabling free permanents off attack triggers. Secondary win conditions include infinite combat loops with Aggravated Assault + Old Gnawbone and direct damage from Terror of the Peaks/Scourge of Valkas.

Primer:

Core Strategy Execution:

1. Early Acceleration (Turns 1-3): Deploy fast mana (Mana Crypt, Mox Diamond, Sol Ring) and dorks (Ignoble Hierarch, Birds of Paradise) to generate 4-6+ mana by turn 2-3.
2. Cheat/Deploy Threats (Turns 2-4): Use Sneak Attack, Hoarding Broodlord, or Jeska's Will to bypass mana costs for Dragons. Cast discounted Dragons like Miirym, Sentinel Wyrm or Goldspan Dragon to pressure opponents.
3. Value Engine Activation (Turns 4-6): Attack with Dragons to trigger The Ur-Dragon’s draw/cheat ability, refueling with cards like Rhystic Study or Necropotence. Tutor for combo pieces (Aggravated Assault, Old Gnawbone) or finishers (Craterhoof Behemoth-equivalent effects via Pathbreaker Ibex).
4. Win Condition Execution:
   • Combat Overkill: Overwhelm with Dragons enhanced by Dragon Tempest, The Reaver Cleaver, or Temur Battlecrier.
   • Infinite Combats: Pair Aggravated Assault with Old Gnawbone (generate infinite Treasures to reactivate Aggravated Assault).
   • Direct Damage: Stack Terror of the Peaks/Scourge of Valkas triggers with multiple Dragon ETBs.

Mulligan Priorities:

• Prioritize hands with 1-2 lands, fast mana, and a Dragon or cheat effect.
• Keep tutors (Demonic Tutor, Worldly Tutor) or card engines (Rhystic Study, The One Ring).
• Avoid hands lacking ramp or with only high-CMC Dragons.

Key Tips:

• Use Hellkite Courser to cheat The Ur-Dragon temporarily for immediate value.
• Protect key pieces with Lightning Greaves and Heroic Intervention.
• Sacrifice Dragons to Sneak Attack before end step, then recur them via Volrath's Stronghold.

Weaknesses:

Critical

• Board Wipes: Lacks mass recursion; relies on rebuilding via hand refill.
• Anti-Cheating Stax: Hushbringer/Torpor Orb nullifies ETB damage and cheat effects.
• Fast Combo Decks: Limited stack interaction to disrupt T3-4 wins.

Moderate

• Artifact Hate: Vandalblast cripples fast mana and equipment.
• Tax Effects: Thalia, Guardian of Thraben slows Dragon deployment.

Minor

• Graveyard Reliance: Limited recursion; Rest in Peace disrupts Volrath's Stronghold.

Most Important Cards:

• The Ur-Dragon (Cost reduction, card advantage engine)
• Sneak Attack (Cheat Dragons, bypassing mana costs)
• Old Gnawbone (Infinite combat enabler, Treasure generation)
• Aggravated Assault (Infinite combat combo piece)
• Hoarding Broodlord (Tutor and cheat enabler)
• Mana Crypt (Explosive early mana)
• Demonic Tutor (Finds key combo/answers)
• Terror of the Peaks (Direct damage win condition)
• Rhystic Study (Card advantage staple)
• Teferi's Protection (Protection against wipes/combat)

Attribute Ratings:

Speed: 8/10
Capable of T3-4 explosive starts with fast mana into Sneak Attack/Hoarding Broodlord, threatening wins by T5-6 via combat or combo.

Resilience: 6/10
Protection spells and recursion (Volrath's Stronghold, Heroic Intervention) mitigate disruption, but board wipes and stax cripple the strategy.

Consistency: 9/10
Dense tutor suite (7+ tutors), abundant card draw, and redundancy in Dragons/ramp ensure reliable access to key pieces.

Interaction: 5/10
Limited to targeted removal (Swords to Plowshares, Cyclonic Rift) and counterspells (Mana Drain, Pyroblast), but lacks broad answers to resolved threats.

Rating Justification:

This deck operates at cEDH-adjacent speeds (T5-6 wins) with optimized mana and tutors but lacks the interaction and compact win conditions of true cEDH lists. Its reliance on combat and vulnerability to wipes place it in the high-power casual tier.

Power level: 7.5 - 8.0
