Inevitable Betrayal

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, 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.
