Overview:

This 5-color Dragon tribal deck leverages The Ur-Dragon's eminence ability to reduce Dragon costs and generate explosive value through combat-triggered card draw/permanent cheating. The strategy focuses on rapid mana acceleration to deploy high-impact Dragons, supported by synergistic enchantments like Temur Ascendancy and Dragon Tempest. While combat damage is the primary win condition, the deck features potent value engines (The Great Henge, Old Gnawbone) and pseudo-infinite combat potential via Hellkite Charger + Savage Ventmaw. The Ur-Dragon acts as both a cost reducer and late-game finisher, though the deck can function temporarily without it using hidden commanders like Miirym, Sentinel Wyrm and Tiamat.

Primer:

Core Strategy Execution:

1. Early Ramp (Turns 1-4): Prioritize land-fetching ramp (Three Visits, Skyshroud Claim) and mana rocks (Arcane Signet, Dragon's Hoard). Use Oracle of Mul Daya and Explore for land drops.
2. Mid-Game Threats (Turns 3-6): Deploy cost-reduced Dragons like Goldspan Dragon, Miirym, or Lathliss, Dragon Queen. Activate value engines: Temur Ascendancy for haste/draw, Elemental Bond for card advantage.
3. Combat Dominance (Turns 5+): Swing with Dragons to trigger Ur-Dragon's draw/cheat effect. Use Atarka, World Render for double-strike lethal or Klauth, Unrivaled Ancient for explosive mana.
4. Finishers:
   • Infinite Combats: Hellkite Charger + Savage Ventmaw (generates 9 mana per attack)
   • Token Swarm: Lathliss + Dragon Tempest for exponential damage
   • Cheated Threats: Utilize Ur-Dragon's attack trigger to free-cast high-CMC permanents like Mirari's Wake.

Mulligan Priorities:

• Keep hands with 2-3 lands (including green/red sources) and at least one ramp spell.
• Prioritize early plays: Birds of Paradise, Farseek, or Herald's Horn.
• Avoid hands without ramp or color-fixing in opening 7.

Key Tips:

• Use Hellkite Courser to cheat The Ur-Dragon from the command zone temporarily.
• Tiamat fetches game-ending Dragons like Miirym + Scion of Draco for keyword soup.
• Protect key pieces with Heroic Intervention and Swan Song.
• Cyclonic Rift resets opponents' boards before alpha strikes.

Weaknesses:

Critical

• Board Wipes: Crux of Fate is the only wipe protection; lacks mass recursion.
• Anti-Tribal Hate: Cursed Totem/Linvala disable mana dorks and Savage Ventmaw.
• Stax Effects: Dranith Magistrate blocks Ur-Dragon's cheat ability; Blood Moon disrupts mana.

Moderate

• Spot Removal on Key Dragons: Losing Miirym or Klauth slows momentum significantly.
• Graveyard Reliance: Darigaaz Reincarnated and Haven of the Spirit Dragon suffer to exile effects.

Minor

• Color-Fixing: Early-game mana issues possible despite fetchlands.
• Limited Stack Interaction: Only 4 counterspells (Stubborn Denial, Swan Song).

Most Important Cards:

• The Ur-Dragon (Cost reduction, value engine)
• Miirym, Sentinel Wyrm (Token duplication, board multiplier)
• Temur Ascendancy (Haste, card draw enabler)
• The Great Henge (Mana, +1/+1 counters, card draw)
• Old Gnawbone (Treasure generation, mana explosion)
• Savage Ventmaw (Combat mana for infinite attacks)
• Hellkite Charger (Infinite combat enabler)
• Tiamat (Tutor 5 game-winning Dragons)
• Klauth, Unrivaled Ancient (Mana generation for explosive turns)
• Cyclonic Rift (Board reset, protection)

Attribute Ratings:

Speed: 7/10
Can deploy lethal Dragon swarms by T6-7 through cost reduction and ramp. Pseudo-infinite combats enable earlier wins with perfect draws.

Resilience: 6/10
Limited protection beyond Heroic Intervention; relies on rebuilding via Ur-Dragon's card advantage after wipes.

Consistency: 8/10
12+ ramp sources, 5 tutors (including Tiamat), and 10+ draw engines ensure Dragon access.

Interaction: 5/10
Focused on protecting its own strategy (counterspells, hexproof) rather than disrupting opponents.

Rating Justification:

This deck threatens T6-7 wins through overwhelming combat or infinite attack phases, supported by exceptional consistency and mana acceleration. While vulnerable to board wipes and stax, its redundancy and value engines justify a high-power casual rating.

Power level: 6.5 - 7.0
