Eldrazi Ramp aims to accelerate into Emrakul, Ugin, or World Breaker via Utopia Sprawl, Sowing Mycospawn, and Talisman of Impulse — use Fatal Push to cut off their ramp creatures early and deny the critical mana threshold. Consign to Memory is your most important sideboard instant here, cleanly answering Emrakul, Ugin, Trinisphere, Grafdigger's Cage, and Disruptor Flute regardless of Cavern of Souls (which renders Force of Negation dead against their creature threats). Ashiok, Dream Render shuts off Sowing Mycospawn's enter-the-battlefield tutor trigger and passively exiles their graveyard, cutting off any Sanctum of Ugin chains or World Breaker recursion. Your primary win condition is landing Goryo's Vengeance into Atraxa or Griselbrand — prioritize setting up that line over trading resources one-for-one, as this matchup rewards the faster combo more than attrition. Surgical Extraction on a key graveyard piece (Emrakul after a discard or removal, Utopia Sprawl) can permanently invalidate major portions of their deck.
