Eldrazi Ramp uses Utopia Sprawl, Icetill Explorer, and Talisman of Impulse to accelerate into early Emrakul, the Promised End and other large Eldrazi threats, backed by Kozilek's Command and Sowing Mycospawn for ramp and interaction. Blood Moon is your most impactful hate piece, cutting off their Eldrazi Temple mana acceleration and preventing Ugin's Labyrinth from providing free colorless mana, which often leaves them unable to cast their large threats on curve. Damping Sphere compounds this by taxing Eldrazi Temple further, and together these two artifacts can completely stall their ramp strategy while you develop an Urza's Saga or Kappa Cannoneer clock. Consign to Memory handles Kozilek's Command (which can destroy your key artifacts), Emrakul on the stack if it resolves, and counters Sowing Mycospawn to prevent additional ramp. Force of Negation provides free backup, particularly important on turns three and four when they could be casting their first large threat and you need to respond without tapping your own mana. Your Engineered Explosives also provides flexible removal against their Utopia Sprawl enchantment to disrupt their acceleration.
