Mono-Green Eldrazi ramps through Fanatic of Rhonas into Emrakul, the Promised End and Ulamog, the Ceaseless Hunger. Thoughtseize taken on an early turn can strip a key ramp piece or top-end threat before it comes down. Feed the Swarm is excellent removal here, killing Fanatic of Rhonas to slow their mana or Fight Rigging before it enables their big spells. Since this is a disruption race rather than a combat-trick race, Mutagenic Growth and Violent Urge come out.
