Eldrazi Ramp is a slower combo-ramp deck that aims to cast large Eldrazi threats through Utopia Sprawl, Sowing Mycospawn, and Ugin's Labyrinth, with post-board Trinisphere, Chalice of the Void, and Torpor Orb specifically targeting combo decks. You are heavily favored in speed since you can win on turn two and they typically need several turns to assemble their mana, but their lockpiece sideboard is potent if they find it on the play. Nature's Claim and Natural State handle Trinisphere, Chalice of the Void, Torpor Orb, and Damping Sphere at one mana, and you should fetch these liberally in games two and three when they are likely to have these disruptive artifacts. Veil of Summer protects your combo turn from their Veil of Summer response and any incidental green disruption. Into the Flood Maw can bounce a Soulless Jailer or lock piece at instant speed to clear the path for your combo on that same turn without needing to spend a separate turn to answer it.
