Overview:

This Temur (G/U/R) Dragon tribal deck leverages Ureni of the Unwritten to cheat high-impact Dragons into play, supported by a suite of ramp, Dragon synergies, and combat-focused payoffs. The primary strategy revolves around deploying Dragons quickly via Ureni's triggered ability or cost reducers like Dragonlord's Servant, then overwhelming opponents with massive flying threats and triggered damage from Terror of the Peaks, Dragon Tempest, and Lathliss, Dragon Queen. Secondary value engines like Old Gnawbone (Treasure generation) and Miirym, Sentinel Wyrm (token duplication) amplify board presence, while Sneak Attack and Selvala's Stampede provide alternative cheat-out avenues. Ureni acts as the linchpin for the deck’s explosiveness but is vulnerable to removal due to its high recast cost.

Primer:

Core Strategy Execution:

1. Early Setup (Turns 1-4): Prioritize ramping with Cultivate, Rampant Growth, Sol Ring, and Dragonlord's Servant. Deploy cost reducers or early Dragons like Rapacious Dragon to accelerate Ureni’s casting.
2. Commander Activation (Turns 5-6): Cast Ureni to cheat in high-value Dragons (e.g., Thrakkus the Butcher, Atarka, World Render). Protect Ureni with haste enablers (Rhythm of the Wild) or Sneak Attack to bypass commander tax.
3. Board Domination (Turns 6-8): Overwhelm with Dragon swarms, doubling triggers via Miirym and Lathliss. Use Terror of the Peaks and Dragon Tempest to burn opponents. Activate finishers like Scourge of the Throne (extra combats) or Thrakkus (power doubling).
4. Alternative Lines: Sneak Attack + recursion (Haven of the Spirit Dragon), Broodcaller Scourge to cheat permanents post-combat, or Hellkite Courser to re-trigger Ureni.

Mulligan Priorities:

• Keep hands with 3+ lands and at least one ramp spell (e.g., Cultivate, Arcane Signet).
• Prioritize cost reducers (Nogi, Draco-Zealot, Sarkhan, Soul Aflame) or early Dragons.
• Avoid hands without green mana or excessive high-cost cards.

Key Tips:

• Use Reflections of Littjara (set to Dragon) to copy Ureni’s trigger or key Dragons.
• Hellkite Courser can cheat Ureni back after removal, avoiding tax.
• Spit Flame provides recurring removal with Dragon ETBs.

Weaknesses:

Critical

• Board wipes (e.g., Farewell, Cyclonic Rift) devastate the creature-heavy strategy; limited recovery outside Haven of the Spirit Dragon.
• Commander dependency: Ureni’s high recast cost (8+ mana) cripples the deck if removed repeatedly.

Moderate

• Anti-flying tech (Sandwurm Convergence, Gravity Well) neutralizes Dragon evasion.
• Artifact/enchantment hate disrupts key pieces like Sneak Attack or Rhythm of the Wild.

Minor

• Mana consistency: Relies on taplands (e.g., Frontier Bivouac) and lacks fetchlands, slowing early turns.

Most Important Cards:

• Ureni of the Unwritten (Cheats Dragons, primary engine)
• Miirym, Sentinel Wyrm (Doubles Dragon ETBs)
• Terror of the Peaks (Burn damage on Dragon entry)
• Sneak Attack (Bypasses mana costs for explosive plays)
• Old Gnawbone (Treasure generation for mana acceleration)
• Thrakkus the Butcher (Doubles Dragon power for lethal swings)
• Dragon Tempest (Haste enabler + direct damage)
• Lathliss, Dragon Queen (Token generation for wide boards)
• Hellkite Courser (Replays Ureni/commanders)
• Rhythm of the Wild (Protection from counters + haste)

Attribute Ratings:

Speed: 6/10

• Can deploy game-winning boards by turns 6-8 via Ureni or Sneak Attack, but lacks fast mana (e.g., Mana Crypt) for earlier spikes.

Resilience: 5/10

• Limited protection (no Heroic Intervention) and heavy reliance on Ureni’s survival. Recursion is sparse outside Haven of the Spirit Dragon.

Consistency: 7/10

• Strong ramp package and card draw (Elemental Bond, Garruk's Uprising) ensure Dragons flow, but tutors are minimal (only Worldly Tutor).

Interaction: 4/10

• Spot removal (Beast Within, Chaos Warp) and counterspells (Counterspell) are present but not abundant. Struggles against noncreature strategies.

Rating Justification:

This deck threatens wins via combat or burn around turns 6-8 with moderate resilience, aligning with the "Focused" tier (6.0). However, its reliance on Ureni and vulnerability to board wipes cap its ceiling, placing it slightly below optimized lists.

Power level: 5.5 - 6.0
