Eldrazi Ramp is a linear big-mana deck that aims to resolve Emrakul, Ugin, Eye of the Storms, or World Breaker before you can establish control, so your priority is attacking their acceleration while holding up answers for their payoffs. Force of Vigor destroys Utopia Sprawl and Talisman of Impulse at instant speed, and doubles as an answer to the Trinisphere and Vexing Bauble they bring in post-board to lock you under three mana. A third Harbinger of the Seas is exceptionally punishing here given their heavy nonbasic land count — Eldrazi Temple, Ugin's Labyrinth, Cavern of Souls, and Stomping Ground all enter tapped, while Collector Ouphe shuts off Talisman of Impulse entirely. Force of Negation and Flare of Denial are your priority interaction for Emrakul and Ugin; Subtlety can tempo back anything that slips through, and Sink into Stupor provides instant-speed bounce for their largest threats. Fblthp, Tamiyo, and Dismember are too low-impact against a deck focused purely on ramping past your interaction curve.
