Eldrazi Ramp is a green ramp deck that accelerates mana through Utopia Sprawl, Sowing Mycospawn, and Talisman of Impulse to deploy early Emrakul, the Promised End or World Breaker threats. This is essentially a race — you both want to deploy large threats quickly, but their Emrakul with the cast trigger is their primary threat while you have the advantage of redundant Tron assembly and Karn's wishboard. Disruptor Flute naming Emrakul, the Promised End preemptively prevents them from casting their key finisher without further disruption. The Stone Brain naming Emrakul, the Promised End surgically removes all copies from the game permanently. Cityscape Leveler and Extinguisher Battleship come in as additional massive threats to give you more closing speed and body count in a race where whoever lands the first unanswered haymaker typically wins. Your Trinispheres are particularly strong against their Utopia Sprawl-based ramp since they must pay three for their mana dorks and cantrips.
