The Keeper

Flying, shroud
At the beginning of your upkeep, you may reveal your library to target opponent. If you do, search your library for a card and exile it, then that opponent names a card. If you searched for a card that isn't the named card, play it without paying its mana cost. Then shuffle your library.
