Eldrazi Tron is almost entirely colorless, making Consign to Memory devastating with its replicate mode able to stop multiple colorless spells like Sowing Mycospawn, Devourer of Destiny, Kozilek's Command, or Expedition Map in a single turn. Vexing Bauble further punishes their reliance on zero-cost effects and cheap artifact mana rocks. Stubborn Denial struggles since most of their key spells and permanents are colorless (it still counters them as noncreature spells, but their land-heavy, ramp-heavy curve means they often have mana up to brute-force through it), and Lightning Bolt is undersized against their large Eldrazi and planeswalkers like Ugin; trim both in favor of the more surgical colorless-hate package. Keep Fatal Push and Leyline Binding as your main removal for Devourer of Destiny, Emrakul, and Karn, the Great Creator.
