The Ur-Dragon five-color Dragon tribal deck built around repeated attacks: the commander discounts Dragon spells, and every Dragon attack draws cards and drops a permanent from hand straight onto the battlefield, so each combat refuels and expands the board. The deck ramps hard into big flying Dragons with cost reducers and treasure makers, then multiplies combat steps so attack triggers, treasure generation and card draw fire again and again within a single turn. How it wins: It swings with a flying Dragon army through extra combat phases, and the mana-generating Dragons let Aggravated Assault or Hellkite Charger loop into effectively unlimited combats and lethal damage. Key roles: - Dragon cost cheating: Reduces or skips Dragon costs and fixes all five colors so huge Dragons land early and in multiples, alongside The Ur-Dragon's eminence discount (Dragonspeaker Shaman, Urza's Incubator, Morophon, the Boundless) - Attack-trigger payoffs: Dragons that generate mana, treasure, tokens or cards whenever they attack or connect, so every combat produces more resources than it costs (Klauth, Unrivaled Ancient, Old Gnawbone, Utvara Hellkite) - Extra combat engine: Untaps the team and adds combat phases, and when paired with mana-producing attackers it loops into near-infinite combats (Aggravated Assault, Hellkite Charger, Ancient Copper Dragon) - Combat amplifiers: Haste, trample, double strike and doubled damage make each extra combat lethal immediately rather than over several turns (Atarka, World Render, Twinflame Tyrant, Temur Ascendancy) - Token multiplication and ETB burn: Copies and extra Dragon tokens, with enter-the-battlefield damage triggers that punish opponents as the board grows, including the Ancient Gold Dragon burn combo (Miirym, Sentinel Wyrm, Terror of the Peaks, Dragon Tempest) - Dragon tutoring and recursion: Finds or rebuys key Dragons to assemble the engine and recover from removal (Tiamat, Ureni of the Unwritten, Rivaz of the Claw)
