Sneak and Show wants to resolve Show and Tell or Sneak Attack and immediately put Emrakul, the Aeons Torn or Griselbrand into play. Mindbreak Trap is our best reactive answer, exiling Show and Tell or Sneak Attack on the stack for free if an opponent has cast three or more spells that turn, stopping the spell before it resolves (though note that once Sneak Attack is on the battlefield, putting a creature into play is an activated ability rather than a spell). If a threat like Griselbrand, Atraxa, or Emrakul resolves, Static Prison cleanly exiles it, as Emrakul's protection from spells that are one or more colors does not prevent Static Prison's enters-the-battlefield ability—an ability of a colored permanent on the battlefield—from targeting it. We trim Manifold Key and Mox Opal, artifact utility and mana rocks that don't help us fight through their explosive, low-interaction combo turn.
