Sneak and Show is racing us to the same type of explosive payoff (Griselbrand, Atraxa, Emrakul) and backs it up with Force of Will, so the matchup comes down to who disrupts the other's hand and resolves a threat first. Our existing Thoughtseize, Unmask, and Cabal Therapy are already excellent at stripping their Show and Tell, Sneak Attack, or Force of Will before they can combo off, and none of our sideboard cards meaningfully speed us up or add relevant interaction against their plan beyond what we already have. We keep the 75 and prioritize using discard proactively on their key enablers rather than holding it reactively, since this matchup is largely decided by whoever discards and resolves first.
