Eldrazi

This is a colorless Eldrazi ramp commander deck built to generate lots of mana quickly and slam huge, game-ending threats. Its core plan is to use mana rocks and land ramp like Sol Ring, Thran Dynamo, Hedron Archive, Burnished Hart, and Solemn Simulacrum to power out massive Eldrazi ahead of curve.

The deck wins by overwhelming the table with big annihilator-style attackers and cast-trigger payoff creatures like Ulamog, the Ceaseless Hunger, Kozilek, the Great Distortion, Artisan of Kozilek, It That Betrays, Void Winnower, and Desolation Twin. Zhulodok, Void Gorger is a major synergy piece, giving your expensive colorless spells extra cascading value, while Conduit of Ruin, Sanctum of Ugin, and Eye of Ugin-style effects help find key threats. Control tools like All Is Dust, Ugin, the Spirit Dragon, Scour from Existence, and Duplicant keep opponents in check while your giant creatures finish the game through combat and sheer inevitability.
