Cedric, Sexy Secret Seeker

Ward {x}, where X is the number of coin
counters you have.
Whenever one or more Rogues or Assassins
you control deal combat damage to an opponent,
exile the top three cards of your library
face down. That opponent may look at them and separate them into a face-down and face-up pile.
Choose one pile to put into your hand, and one
pile to put into your graveyard.
