Recall X where X is equal to the number of instant and sorcery cards in your graveyard and in exile. (If you cast this spell from your hand, exile it with X time counters on it as it resolves. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost.)
