Chrono Mage

Suspend 3 — {0} (Rather than cast this card from
your hand, you may pay {0} and exile it with 3 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. It has haste.)
When Chrono Mage enters the battlefield, exile
target permanent, then return that card to the battlefield at the beginning of the next end step.
