Sherlock Holmes

Deduction (Whenever an opponent casts a spell, you may look at the top card of their library. You may put that card on the bottom of their library.)

At the beginning of your upkeep, you may ask target player a yes-or-no question. If you do, that player answers the question truthfully and abides by that answer if able until end of turn.

"I never guess. It is a shocking habit - destructive to the logical faculty."
