Consign to Memory is excellent here, countering the triggered abilities off Devourer of Destiny and Emrakul, the Promised End's cast triggers, as well as colorless Kozilek's Command activations, stripping the deck of its biggest swings before they resolve. Emperor of Bones lets you exile key cards like Basking Broodscale or Emrakul out of their graveyard before Kozilek's Command or Devourer of Destiny can find value there, and doubles as its own recursive threat. Teferi comes out since their deck has few instants to punish and its bounce mode is weak against a board of Eldrazi Spawn tokens, while trimming lands slightly smooths the curve for the incoming spells. Prioritize using Solitude and Fatal Push proactively on Basking Broodscale and Glaring Fleshraker before they generate token value.
