Sneak and Show wants to resolve Show and Tell or Sneak Attack to cheat in Atraxa, Grand Unifier, Emrakul, the Aeons Torn, or Griselbrand, so Force of Negation is premium, letting us counter either enabler for free on their turn. Containment Priest is excellent insurance since it exiles any nontoken creature that enters without being cast, shutting down both Show and Tell and Sneak Attack as ways to cheat creatures into play. Stifle has limited upside here since their plan isn't built around activated/triggered abilities, and Consign to Memory mostly misses since their big threats are colored creature spells, so both get trimmed. Keep Daze and Wasteland at full count since disrupting their fast mana (Ancient Tomb, City of Traitors) remains valuable.
