This is a colorless Eldrazi ramp deck that builds huge amounts of colorless mana from rocks, Tron lands and doublers to cast enormous Eldrazi titans. Emrakul untaps all lands when cast, so a big turn can keep going into a second threat, and its exile ability turns it into a mana source early. Cast triggers, cost reducers and cascade or copy effects get the most out of every colorless spell. Mystic Forge and Sensei's Divining Top let the deck keep casting colorless spells off the top of the library. How it wins: It attacks with annihilator and evasive titans whose cast triggers strip opponents' boards, or it loops Sensei's Divining Top with Glaring Fleshraker and either Mystic Forge or Echoes of Eternity for endless Eldrazi Spawn and pings to every opponent. Key roles: - Colorless mana engine: Tron lands, big mana rocks and effects that add extra colorless mana make double-digit casts possible early. Emrakul's land untap turns that mana into two big spells in one turn. (Urza's Tower, Forsaken Monument, Ultima, Origin of Oblivion) - Cost reduction and cheating: Effects that make colorless or Eldrazi spells cheaper, or free, shrink the titans' costs and stack with Emrakul's untap. (Eye of Ugin, Darksteel Monolith, Ugin, the Ineffable) - Cast-trigger amplification: The titans' value comes from casting them. Cascade, spell copies and doubled triggers multiply the board wipes, card draw and control-stealing they bring. (Echoes of Eternity, Zhulodok, Void Gorger, Kozilek, Butcher of Truth) - Annihilator and lockout finishers: Huge attackers make opponents sacrifice permanents, exile their libraries or block their spells, while colorless sweepers clear colored boards and leave this deck's own untouched. (Ulamog, the Infinite Gyre, It That Betrays, All Is Dust) - Top-of-library casting combo: Mystic Forge and Sensei's Divining Top let the deck recast colorless spells endlessly. Each cast makes a Spawn with Glaring Fleshraker, which pings every opponent as the Spawn enters and pays for the next loop. (Sensei's Divining Top, Mystic Forge, Glaring Fleshraker) - Titan tutoring and protection: Tutors set up specific titans, and equipment plus colorless counterspells give haste and keep the giant threat alive. (Conduit of Ruin, Sanctum of Ugin, Lightning Greaves)
