Eldrazi Ramp is a big-mana deck that uses Utopia Sprawl, Malevolent Rumble, and Eldrazi Temple to deploy Emrakul or Ugin, Eye of the Storms well ahead of schedule, with Kozilek's Return as a sweeper that wipes your entire creature combo. Kozilek's Return is your most dangerous card — it costs only two mana and can be cast off Eldrazi Temple, wiping Young Wolf, Badgermole Cub, and Delighted Halfling before you can combo, and it can be recurred from the graveyard by Emrakul's cast trigger. Force of Vigor destroys Ugin's Labyrinth, Chalice of the Void, and Torpor Orb from the sideboard at instant speed, protecting your creature-based combo setup. Thoughtseize strips Emrakul or Ugin before they can be deployed, buying critical turns to assemble your win. Culling Ritual can clear their mana-dork and smaller permanent package in a single turn while generating significant mana to accelerate your own combo.
