Witch's Tutor

Search your library for a card and exile it face
down. Shuffle your library. Choose a card type.
An opponent guesses whether the exiled card is a
card of that type. Reveal the exiled card. If the opponent guessed wrong, add it to your hand. (Artifact, creature, enchantment, instant, land, planeswalker, sorcery, and tribal are card types.)
"The truth? Dear me, where would the fun be in that?"
