This is a five-color Dragon tribal ramp deck. It works toward casting Tiamat, whose cast trigger tutors up to five different Dragons and turns one big spell into a full hand of threats. Heavy mana acceleration, Dragon-specific mana and cost reducers make those expensive Dragons castable quickly. Enter-the-battlefield damage, token copying and attack-trigger payoffs then overwhelm opponents with a flying army. How it wins: It deploys a stream of Dragons that ping opponents on entry and swing for huge doubled flying damage, with Call the Spirit Dragons, the Ancient Gold Dragon plus Dragon Tempest damage loop and the Miirym, Bladewing and Terror of the Peaks infinite loop as alternate finishes. Key roles: - Tribal mana and cost reduction: Dragon-only mana sources and discounts shave the colored and generic costs off big Dragons, so several can come down per turn, especially after Tiamat refills the hand. (Morophon, the Boundless, Dragonspeaker Shaman, Rivaz of the Claw) - Tutoring and Dragon chaining: Tiamat's search is backed by effects that dig for Dragons, cast them from the top of the library or put them straight onto the battlefield. Each Dragon leads into the next, and general tutors find the key engines. (Ureni of the Unwritten, Korlessa, Scale Singer, Maelstrom of the Spirit Dragon) - Entry-trigger damage and copying: Every Dragon that enters deals damage scaling with the number of Dragons or with the entering creature's power. Token copiers and token makers multiply those triggers, and the same package forms the infinite loop. (Terror of the Peaks, Scourge of Valkas, Miirym, Sentinel Wyrm) - Combat amplification: Haste enablers let fresh Dragons attack at once, then double strike, power doubling and damage doubling turn one air strike into a lethal blow. (Atarka, World Render, Thrakkus the Butcher, Twinflame Tyrant) - Attack-trigger value: Dragons that generate mana, Treasures, cards or creatures when they attack or connect feed further Dragon casts mid-combat and refuel the hand. (The Ur-Dragon, Klauth, Unrivaled Ancient, Ancient Copper Dragon) - Resilience and alternate wins: Dragon recursion, ward and indestructibility keep the board intact through removal. Call the Spirit Dragons gives a five-color upkeep win once Dragons of every color are in play. (Call the Spirit Dragons, Bladewing the Risen, Rith, Liberated Primeval)
