Sneak and Show wants to cheat Emrakul, the Aeons Torn or Griselbrand into play via Show and Tell or Sneak Attack and end the game immediately, so Kiora's Dismissal is excellent tech here since it can return their Sneak Attack or Omniscience enchantment to hand, undoing their entire turn. Into the Flood Maw can bounce a cheated-in Griselbrand before it attacks, though note it cannot target Emrakul, the Aeons Torn since it has protection from spells that are one or more colors. Bridge from Below is unreliable since this matchup is almost entirely a race with little combat, so we trim it along with Careful Study for more proactive interaction. Prioritize racing fast since their deck has very few ways to interact with our graveyard plan directly.
