Ulamog, the Ceaseless Hunger

Gameplan

Ramp aggressively into 10+ mana, slam Ulamog to exile two of the worst permanents on board (lands, problem permanents, planeswalkers), then attack to mill opponents out 20 cards at a time. The deck is a colorless Eldrazi ramp shell that grinds the game through massive mana acceleration and beats face with indestructible threats.

Key Cards

• Eye of Ugin — Drops Eldrazi spell costs by 2 colorless, making Ulamog and friends dramatically cheaper.
• Sanctum of Ugin — Tutors another Eldrazi titan onto the battlefield after casting a big spell, chaining threats.
• Ancient Tomb — Doubles your mana output early, a key accelerant in a colorless ramp shell.
• Eldrazi Temple — Adds two colorless for Eldrazi, accelerating toward your 10-drop.
• Kozilek, Butcher of Truth — Refills your hand on cast and gives a second indestructible/annihilator-style finisher.
• Endless Atlas — Pure colorless card advantage to keep the gas flowing in a colorless deck.

Upgrade Path

Lean into ramp density with cards like Mana Vault, Grim Monolith, Mishra's Workshop, and Thran Dynamo to consistently hit 10 mana by turn 5-6. Add the other titans (Emrakul, Kozilek) plus reanimation-adjacent cheats like Spawnsire of Ulamog or Eldrazi Aggressor effects, and protect your engine with All Is Dust and Karn, the Great Creator to lock out artifact-reliant tables.
