This is a mono-colorless Eldrazi ramp deck that turns Omnath, Locus of the Void into a mana battery. Land drops and fetches trigger landfall for two colorless each. Horizon Stone and Omnath's own text keep unspent mana from emptying between steps and phases, while Doubling Cube and the Monoliths multiply the pool. That stockpile feeds a top end of titanic Eldrazi and colorless bombs, with cost reducers, cast triggers and copy effects squeezing extra value out of every colorless spell. How it wins: It lands 10-mana Eldrazi titans like Ulamog, Kozilek and Emrakul to annihilate, exile and lock opponents, swings with a pumped Omnath, or loops Sensei's Divining Top with Glaring Fleshraker and Mystic Forge or Echoes of Eternity for endless colorless casts that ping everyone out. Key roles: - Landfall fuel: Fetches, land-searching artifacts and creatures, and extra land drops turn each land into two more colorless mana through Omnath, and lands can be replayed from the graveyard (Sword of the Animist, Burnished Hart, Crucible of Worlds) - Mana banking and multiplication: Mana that carries across phases and gets doubled lets Omnath grow huge and lets the deck chain several giant spells in one turn (Horizon Stone, Doubling Cube, Forsaken Monument) - Big rocks and untap tricks: Monoliths, Urza lands and untappers produce bursts of colorless mana and can go off with artifact untapping (Grim Monolith, Basalt Monolith, Unwinding Clock) - Colorless cast payoffs: Cost reducers, cascade, copying and cast triggers reward every colorless spell and chain free plays (Echoes of Eternity, Zhulodok, Void Gorger, Ugin, Eye of the Storms) - Eldrazi titan finishers: Huge Eldrazi with cast triggers exile permanents, mill libraries, draw cards and steal turns, backed by tutoring lands that fetch them (Ulamog, the Ceaseless Hunger, Kozilek, Butcher of Truth, Eye of Ugin) - Top-deck combo engine: Casting colorless spells off the library with a Top that redraws itself generates Spawn and damage triggers without end (Sensei's Divining Top, Mystic Forge, Glaring Fleshraker)
