Feign - Door of Riddles

Whenever a creature an opponent controls
attacks you, reveal your hand, then shuffle
your hand face-down in a pile. That creature's
controller must name a card in your hand.
Reveal the top card of your pile; If it is the named
card, discard that card and that creature is able
to continue attacking you. If it is not the named
card, that creature is untapped and removed from
combat. Whenever a creature is untapped and
removed from combat this way, return a
discarded card this way back to
