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 advantage and permanent cheating. The primary strategy involves ramping into high-impact Dragons, overwhelming opponents with flying threats enhanced by synergies like Miirym, Sentinel Wyrm (token duplication), Lathliss, Dragon Queen (token generation), and Thrakkus the Butcher (power doubling). Secondary win conditions include direct damage from Terror of the Peaks/Scourge of Valkas triggers and combat tricks like Atarka, World Render's double strike. The commander serves as both an enabler (cost reduction) and a late-game finisher, though the deck can function without it.

Primer:

Core Strategy Execution:

1. Early Setup (T1-4):
   • Prioritize land-fetching ramp (Farseek, Cultivate, Wayfarer's Bauble) and cost reducers (Dragonlord's Servant, Dragonspeaker Shaman).
   • Deploy value artifacts like Dragon's Hoard or Chromatic Lantern to fix mana.
2. Midgame Threats (T4-6):
   • Cast key Dragons: Miirym, Sentinel Wyrm doubles threats, Savage Ventmaw generates combat mana, Thunderbreak Regent punishes interaction.
   • Use Tiamat to tutor critical Dragons like Scourge of the Throne (extra combats) or Morophon, the Boundless (further cost reduction).
3. Endgame (T6+):
   • Overwhelm with scaled threats: Crucible of Fire amplifies board presence, Thrakkus the Butcher enables one-shot kills via doubled power.
   • Leverage Ur-Dragon's attack trigger to cheat in game-enders like Drakuseth, Maw of Flames or Bogardan Hellkite.

Mulligan Priorities:

• Keep hands with 3+ lands including at least two colors
• Prioritize early ramp (cost reducers > land fetch > mana rocks)
• Value hands containing a Dragon payoff (Miirym, Lathliss) or card engine (Dragon's Hoard, Sunbird's Invocation)

Key Tips:

• Sequence cost reducers before big Dragons - Dragonspeaker Shaman enables T4 The Ur-Dragon
• Use Rivaz of the Claw to recur key Dragons like Terror of the Peaks from graveyard
• Sunbird's Invocation can chain into free spells when casting high-CMC Dragons
• Activate Scourge of Valkas's pump ability before damage triggers resolve

Weaknesses:

Critical

• Minimal protection against board wipes (only Heroic Intervention missing)
• Heavy reliance on 6+ CMC creatures makes it vulnerable to early aggression

Moderate

• Susceptible to Cursed Totem/Linvala shutting off Savage Ventmaw/Rivaz
• Limited stack interaction (only Counterspell, Dragon's Fire for key threats)

Minor

• Some enters-tapped lands slow early development
• Token strategies can outpace Dragon snowballing

Most Important Cards:

• Miirym, Sentinel Wyrm (Token duplication engine)
• The Ur-Dragon (Cost reduction & value generator)
• Tiamat (Tutor 5 game-winning Dragons)
• Savage Ventmaw (Combat mana for post-combat plays)
• Scourge of the Throne (Extra combat enabler)
• Thrakkus the Butcher (Power doubler for OTKs)
• Dragon's Hoard (Ramp + card draw)
• Terror of the Peaks (Non-combat damage source)
• Chromatic Lantern (Mana fixing for 5-color)
• Sunbird's Invocation (Value multiplier)

Attribute Ratings:

Speed: 5/10

• Can deploy threatening boards by T5-6 but lacks fast mana (e.g., Mana Crypt) or T4 win combos.

Resilience: 4/10

• Limited protection spells and graveyard recursion beyond Rivaz of the Claw/Pulse of Murasa.

Consistency: 6/10

• Multiple cost reducers and Tiamat tutoring provide reliable access to threats, but lacks blue's premium card selection.

Interaction: 3/10

• Spot removal suite (Swords, Putrefy) is present but sparse; minimal counterspells/stax.

Rating Justification:

This deck demonstrates focused Dragon synergy with strong late-game potential but suffers from typical midrange timings and vulnerability to disruption. Its ability to threaten wins via combat around T7-8 and moderate consistency place it just above upgraded precons, while the lack of infinite combos and limited interaction cap its ceiling.

Power level: 4.5 - 5.0
