Suspend 7— (Rather than cast this card from your hand, you may pay and exile it with seven time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost. It has haste.)

Whenever a card is put into an opponent's graveyard from anywhere, if this card is suspended, you may remove a time counter from this card.
