Extraplanar Portal

Suspend 3 — {3} (Rather than cast this card
from your hand, pay {3} 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.)
{t}: Exile Extraplanar Portal, you may cast an
exiled spell other than Extraplanar Portal
without paying its mana cost.
