Time Eater

Suspend 5—{2}{u}{u} (Rather than cast this card
from your hand, pay {2}{u}{u} and exile it with five
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.)
Whenever you draw a card, you may return a
card from your graveyard to your hand.
{2}{u}: You may tap or untap another target
permanent.
