Manifestation Mirror

Suspend 4 —{3} (Rather than cast this card from your hand, pay {3} and exile it with four 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 your library for a creature card and put that creature onto the battlefield with Manifestation Mirror attached to it. If Manifestation Mirror becomes unattached from this creature, exile it.
