Overview:

This Ur-Dragon deck focuses on leveraging cost reduction and combat triggers to flood the board with Dragons, utilizing both overwhelming creature presence and specific combo lines. While it has potent late-game capabilities and some combo potential, its reliance on high-cost permanents and moderate interaction keeps it in the optimized casual range.

Primer:

Core Strategy: The deck aims to cheat out Dragons early via The Ur-Dragon's eminence and cost reducers like Morophon, the Boundless, then generate explosive value through attack triggers (drawing cards and free permanents). Key win conditions include:

• Combat Overload: Overwhelm with flying threats enhanced by Crucible of Fire and Atarka, World Render.
• Infinite Combats: Savage Ventmaw + Hellkite Charger generates infinite combat phases when mana from Ventmaw covers Charger's activation.
• ETB Burn: Dragon Tempest, Terror of the Peaks, and Scourge of Valkas turn Dragon deployments into direct damage.

Mulligan Priorities:

• 3+ lands with at least two colors.
• Early ramp (Farseek, Delighted Halfling) or cost reducers (Herald's Horn).
• Avoid hands without acceleration or color fixing.

Key Tips:

• Sequence Reducers: Prioritize playing Dragonspeaker Shaman or Urza's Incubator before deploying big Dragons.
• Protect Combos: Use Cavern of Souls to ensure key Dragons resolve. Save Animate Dead for Bladewing the Risen recursion.
• Stagger Threats: Deploy one impactful Dragon at a time to mitigate board wipe blowouts.

Avoid Traps:

• Overextending into board wipes without Kindred Discovery or Dragon's Hoard for recovery.
• Holding back attackers unnecessarily—The Ur-Dragon’s draw/cheat ability rewards aggression.

Weaknesses:

Critical:

• Relies on 6+ mana creatures vulnerable to counters/removal.
• Limited protection for combo pieces (1-2 counterspells).

Moderate:

• Slow recovery from mass removal (Cyclonic Rift, Farewell).
• Mana base leans heavily on tapped lands, slowing early turns.

Minor:

• Graveyard dependency for Scion of the Ur-Dragon/Bladewing lines.

Most Important Cards:

• Savage Ventmaw
• Hellkite Charger
• Morophon, the Boundless
• Terror of the Peaks
• Scourge of Valkas
• Dragon Tempest
• Kindred Discovery
• Klauth, Unrivaled Ancient
• Ancient Brass Dragon
• Bear Umbra

Attribute Ratings:

Speed: 6/10
Can deploy game-ending boards by T7-8 naturally or combo as early as T6 with perfect draws. Ramp and cost reduction mitigate high mana costs.

Resilience: 4/10
Weak to targeted removal on key enablers and board wipes. Limited recursion outside Animate Dead/Haven of the Spirit Dragon.

Consistency: 6/10
Moderate tutor density (Sarkhan's Triumph, Orb of Dragonkind) and strong card draw from attack triggers. Redundant cost reducers help.

Interaction: 4/10
Relies on 3-4 targeted removals (Swords, Anguished Unmaking) and two board wipes. No free counterspells.

Rating Justification:

The deck sits between 5.0 (Optimized Casual) and 5.5 (High-Power Casual). It outpaces precons with combo potential and explosive turns but lacks the fast mana, free interaction, and redundancy seen in true high-power decks. Its T7-10 win window aligns with the 5.0-5.5 rubric, though it can occasionally goldfish faster with ideal draws.

Power level: 5.0 - 5.5
