Big-mana colorless Eldrazi ramp that uses Ulalek as a copy engine. Each Eldrazi spell cast can pay {C}{C} to copy every spell on the stack plus all other triggered and activated abilities, so cast triggers get doubled or multiplied: Ulamog exiles, Kozilek's draw, Ugin's exile, Sowing Mycospawn's land fetch, Nulldrifter's draw. Heavy colorless ramp feeds it: Urza lands, monoliths with untappers, Kinnan, Forsaken Monument and Eldrazi cost reducers. Flash enablers let the cast triggers fire on opponents' turns. How it wins: It resolves copied titans like Ulamog, Kozilek and It That Betrays to strip boards and libraries and swing with annihilator, or assembles Ulalek with Glaring Fleshraker and Echoes of Eternity for infinite Spawn tokens and damage to each opponent. Key roles: - Cast-trigger copying: Ulalek and its helpers multiply "when you cast" effects, turning one titan into multiple exiles, mill events, card draws or land fetches, often while copying the titan spell itself (Ulamog, the Ceaseless Hunger, Echoes of Eternity, Abstruse Archaic). - Colorless mana engine: Tron lands, monoliths, Sol Ring and mana doublers generate large amounts of colorless mana to pay for both titans and Ulalek's {C}{C} copy tax. Untap effects loop the artifacts for extra mana (Grim Monolith, Forsaken Monument, Kinnan, Bonder Prodigy). - Cost reduction and cheating: Effects that discount or zero out colorless and Eldrazi spells let multiple titans land in one turn (Eye of Ugin, Darksteel Monolith, Ugin, the Ineffable). - Flash casting: Flash granters let Eldrazi and their cast triggers come down at instant speed for surprise copies and protection (Liberator, Urza's Battlethopter, Skittering Cicada, Leyline of Anticipation). - Colorless spell payoffs: Cards that reward each colorless cast turn every Eldrazi into removal, tokens or burn, and they become an infinite loop with the commander (Glaring Fleshraker, Ugin, Eye of the Storms, Ugin's Binding). - Board-control finishers: Annihilator titans and colored-permanent sweepers dismantle opponents while the colorless board survives (It That Betrays, All Is Dust, Kozilek, Butcher of Truth).
