Use sacrificing and eldrazi spawn to trigger the Quest for the Gravelord and Hand of Emrakul, preferably by turn 3.
Ideally:
Turn 1: Swamp, QfhG
Turn 2: Mountain, Spawning Breath
Turn 3: Swamp, Mortician Beetle, Brood Birthing, sac 4 spawn, Play Hand of Emrakul and trigger OfhG.
Im thinking of adding Green for more eldrazi spawn generators. Comments welcome.
