Expose the Culprit
A two-mana instant built to pull double duty on a mechanic that lives and dies by information asymmetry. The first mode is the obvious one: flip an opponent's face-down attacker into whatever it actually is at a moment they weren't ready to reveal it, or unmask your own to trigger a disguise ability early. The second mode is where the design gets slippery. It gathers your own face-up creatures that carry disguise, shuffles them into a fresh pile, and puts them back down as generic 2/2s with ward, launching a new guessing game from scratch. The creatures reset this way were known quantities a moment ago: the opponent could see exactly which body was the bomb, plan removal around it, block it correctly. After the shuffle, that certainty is gone, and re-earning it costs a ward tax on every attempt to check. The reshuffle quietly protects a creature about to eat targeted removal: scrambling a face-up threat back into an indistinguishable body is a way to launder it through the fog of face-down combat. The effect only works with creatures that have disguise, which keeps it from becoming a universal blink-and-hide button, but inside a deck built to trade on hidden information it turns a cheap instant into a rug-pull. This is less removal or protection than a manipulation of what the opponent is allowed to know, and that is a rarer axis to attack than most instants at this cost bother with.
