Ulalek turns every Eldrazi spell into a chance to double the board's on-cast value: for {C}{C} it copies every spell on the stack and every other triggered or activated ability on the stack, so cast triggers like stealing creatures, ramping off an opponent's lands, tapping blockers, reanimating, or exiling permanents fire twice. The list is a colorless Eldrazi ramp deck, built on colorless mana rocks, painlands, Eldrazi-specific lands and Scion/Spawn tokens. That mana funds both expensive titans and Ulalek's {C}{C} tax, and a colorless-matters package makes those spells cheaper, bigger and harder to answer. How it wins: Doubled cast triggers and huge annihilator and trample threats strip opponents' boards and push lethal combat damage, backed by colorless sweepers that leave only the deck's own permanents standing. Key roles: - Cast-trigger payoffs: Eldrazi with "when you cast" abilities are the main things Ulalek copies, doubling theft, land stealing, reanimation, tapping and copied-creature tokens as the threats come down (Hideous Taskmaster, Oblivion Sower, Artisan of Kozilek). - Colorless mana and Scion fuel: Rocks, colorless-producing lands and sacrificeable Spawn/Scion tokens ramp into the top end and pay Ulalek's {C}{C}, with token makers also feeding sacrifice effects (Forsaken Monument, Glaring Fleshraker, Eldrazi Temple). - Colorless cost reduction and tutoring: These cards discount colorless or Eldrazi spells, play them from the top of the library, or dig for them, so big threats arrive early and often (Ugin, the Ineffable, Mystic Forge, Morophon, the Boundless). - One-sided colorless wipes: Because the deck's own permanents are colorless, these sweepers and color-based removal wreck opponents while leaving its board intact (All Is Dust, Selective Obliteration, Kozilek's Return). - Annihilator and combat finishers: Massive bodies, anthems and evasion turn attacks into forced sacrifices and lethal trample damage (Eldrazi Conscription, Ulamog's Crusher, Twins of Discord). - Power-based card flow: Big creatures convert high power into card draw to refill after deploying titans (Garruk's Uprising, Rishkar's Expertise, Return of the Wildspeaker).
