with three time counters on it. At the beginning of
your upkeep, remove a time counter from it. When the
last is removed, sacrifice it.)
When Crack in Time enters the battlefield and at
the beginning of your precombat main phase, exile
target creature an opponent controls until Crack in
Time leaves the battlefield.
