Inevitable Betrayal
Sorcery
Suspend 3—{1}{U}{U} (Rather than cast this card from your hand, pay {1}{U}{U} and exile it with three time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost.) Search target opponent's library for a creature card and put that card onto the battlefield under your control. Then that player shuffles.
