Overview:

This 5-color Dragon tribal deck helmed by Tiamat focuses on ramping into massive flying threats while leveraging Dragon synergies for value. Tiamat serves as the primary engine, tutoring key Dragons like Atarka, World Render, Lathliss, Dragon Queen, and Keiga, the Tide Star when cast. The strategy combines combat dominance through evasive Dragons with incremental value from enter/attack triggers and enchantments like Dragon Tempest and Temur Ascendancy. While lacking infinite combos, it can create explosive turns using extra combat phases (Scourge of the Throne) and token generation to overwhelm opponents.

Primer:

Core Strategy Execution:

1. Early Ramp (Turns 1-4): Prioritize land-fetching with Encroaching Dragonstorm, Evolving Wilds, and mana rocks. Deploy cost reducers like Dragonlord's Servant and Nogi, Draco-Zealot.
2. Commander Deployment (Turns 5-7): Cast Tiamat to fetch a toolbox of Dragons - typically including Hellkite Courser (to re-cast Tiamat), Broodcaller Scourge (permanent cheating), and Dragonlord Atarka (board control).
3. Mid-Game Dominance: Use Dragon synergies like Lathliss, Dragon Queen tokens, Temur Ascendancy card draw, and Dragon Tempest burn to pressure opponents. Activate Kessig Wolf Run for trample finishers.
4. Late-Game Closers: Deploy Craterhoof Behemoth with a wide board or chain extra combat phases via Scourge of the Throne. Recur key pieces with Eerie Ultimatum.

Mulligan Priorities:

• Keep hands with 3+ lands including green sources.
• Prioritize early ramp (Sol Ring, Encroaching Dragonstorm, Dragonlord's Servant).
• Look for at least one Dragon payoff card (Temur Ascendancy, Dragon Tempest).
• Avoid hands with only high-CMC Dragons and no ramp.

Key Tips:

• Use Hellkite Courser to cheat Tiamat back after removal.
• Broodcaller Scourge can cheat Craterhoof Behemoth if you deal 5+ combat damage.
• Deceptive Frostkite copies your biggest Dragon while retaining Dragon synergies.
• Reflections of Littjara on Dragons creates exponential threats.

Weaknesses:

Critical

• Extreme vulnerability to board wipes (only Heroic Intervention-style protection missing).
• Heavy reliance on commander (7CMC) with limited protection.

Moderate

• Slow mana base (13+ tapped lands) delays critical turns.
• Weak to flying hate and Propaganda-style effects.

Minor

• Limited stack interaction (only Negate, Chaos Warp).
• Some anti-synergy between "power 4+" payoffs and smaller utility creatures.

Most Important Cards:

• Tiamat (Tutor 5 Dragons, deck engine)
• Hellkite Courser (Commander recursion)
• Craterhoof Behemoth (Primary finisher)
• Dragon Tempest (Haste enabler & burn)
• Lathliss, Dragon Queen (Token generation)
• Scourge of the Throne (Extra combats)
• Broodcaller Scourge (Permanent cheating)
• Eerie Ultimatum (Graveyard recovery)
• Temur Ascendancy (Card draw & haste)
• Encroaching Dragonstorm (Ramp & recursion)

Attribute Ratings:

Speed: 6/10
Can deploy game-ending boards by T7-8 through ramp and Tiamat tutoring, but lacks explosive early combos.

Resilience: 5/10
Limited protection spells and heavy commander dependency make it vulnerable to disruption, though Eerie Ultimatum provides late-game recovery.

Consistency: 7/10
Tiamat's tutor effect ensures Dragon access, while multiple cost reducers and land-searching enchantments smooth mana needs.

Interaction: 4/10
Relies on spot removal like Swords to Plowshares and Chaos Warp but lacks counterspell density or stax elements.

Rating Justification:

This deck demonstrates focused Dragon synergy with strong late-game potential but suffers from a slow mana base and vulnerability to common disruption. Its T7-8 win capability through combat aligns with Optimized Casual tiers, while resilience limitations prevent higher rankings.

Power level: 5.0 - 5.5
