Eldrazi Ramp wants to accelerate with Utopia Sprawl, Talisman of Impulse, and Eldrazi Temple into game-ending threats like Emrakul, the Promised End and World Breaker, so the race is yours to win — your cascade engine is faster than their mana development in most games. Post-board they lean heavily on Grafdigger's Cage and Trinisphere to shut off Living End entirely, making Force of Vigor and Foundation Breaker (cycled pre-combo, rebornished when Living End resolves) critical answers to keep in hand until you're ready to combo. Inevitable Betrayal is exceptional here: as a sorcery it steals their Emrakul or World Breaker outright, neutralizing their biggest threat and often closing the game immediately. Keep all four Force of Negation and Subtlety to protect your Living End on the stack and flash in against a tapped-out Emrakul cast; Subtlety in particular can bounce Emrakul back to hand at instant speed, buying a turn if they resolve it through your disruption.
