Tiamat, The Dragon Queen

Five-color Dragon tribal Commander deck centered on Tiamat. The plan is to ramp hard, fix all five colors, then land Tiamat to tutor up a suite of Dragons that fit the board state and overwhelm the table with huge flying threats.

Key synergies:

• Cost reduction/ramp: Sol Ring, Arcane Signet, Farseek, Cultivate, Nature’s Lore, Dragonlord’s Servant, Dragonspeaker Shaman help power out expensive Dragons quickly.
• Dragon payoff engines: Tiamat, Miirym, Sentinel Wyrm, Lathliss, Dragon Queen, Scourge of Valkas, Terror of the Peaks, Temur Ascendancy, Garruk’s Uprising, and Kindred Discovery turn each Dragon into more bodies, damage, cards, and haste.
• Big combat finishers: Atarka, World Render, Thrakkus the Butcher, Klauth, Old Gnawbone, Ancient Copper Dragon, and Balefire Dragon let the deck snowball through combat and close games fast.
• Toolbox/tutors and interaction: Worldly Tutor, Eladamri’s Call, Sarkhan’s Triumph, Demonic Tutor
