The deck is a five-color Dragon tribal ramp deck that uses The Ur-Dragon's eminence discount and heavy mana fixing to land big flying Dragons early. It then attacks with them to draw cards and drop free permanents straight from hand. Every Dragon entering or attacking feeds layered triggers: burn on entry, token copies and extra Dragons, Treasure and mana bursts. Damage doublers and extra combats turn a single attack into a lethal swing. How it wins: It overwhelms the table with a growing air force of Dragons whose entry burn and amplified, often double-striking or repeated combat damage finishes opponents, with Aggravated Assault loops alongside Savage Ventmaw or Ancient Copper Dragon and the Dragon Tempest plus Ancient Gold Dragon burn as combo finishes. Key roles: - Ramp and Dragon cost reduction: Land fetching, color-fixing rocks, and Dragon-specific discounts stack on top of the commander's eminence, so seven- and eight-drops come down years ahead of schedule. Dragon-only mana lands and the free-cast enchantment push this to the extreme. (Urza's Incubator, Dracogenesis, Three Visits) - Cheating Dragons into play: The Ur-Dragon's attack trigger, combat-damage drops, and library-digging Dragons put permanents onto the battlefield without casting them, while tutors refill the hand with the best threats. (Ureni of the Unwritten, Tiamat, Broodcaller Scourge) - Enter-the-battlefield burn: Every creature or Dragon entering pings any target, scaled by power or by Dragon count. Mass entries become removal and direct damage to players. (Terror of the Peaks, Scourge of Valkas, Dragon Tempest) - Dragon multiplication: Nontoken Dragons arriving create copies or extra Dragon tokens, and attacks spawn more. This grows both the board and the number of burn and draw triggers. (Miirym, Sentinel Wyrm, Lathliss, Dragon Queen, Utvara Hellkite) - Combat amplification and extra combats: Haste lets new Dragons swing immediately, and double strike, trample, and damage doubling or tripling make each hit enormous. Untap-and-repeat combat with mana-on-attack Dragons creates the infinite combat loops. (Aggravated Assault, Fiery Emancipation, Atarka, World Render) - Combat-damage payoffs: Dragons that connect generate huge Treasure, card, or token bursts that fuel further plays and the combo turns, backed by draw engines keyed to big creatures entering or attacking. (Ancient Copper Dragon, Old Gnawbone, Kindred Discovery)
