Dimir Control vs Sneak and Show

Sneak and Show wants to resolve Show and Tell or Sneak Attack into Emrakul, the Aeons Torn, Atraxa, Grand Unifier, or Griselbrand, all threats that our cheap creature removal like Fatal Push and Snuff Out cannot touch since Emrakul can't be countered or meaningfully answered by -X/-X or destroy effects at this size, and Snuff Out/Fatal Push don't interact with their key enablers at all. Consign to Memory comes in to cheaply counter their colorless Lotus Petal-fueled sequencing and their noncreature spells like Sneak Attack or Show and Tell itself before the payoff hits. Force of Negation is a premium answer here since it can be cast for free on their turn to stop Show and Tell, Sneak Attack, or any other noncreature spell outright. Stock Up is cut for being too slow against a deck that can win within a turn or two of resolving its payoff.
