Festering March

Creatures your opponents control get -1/-1 until end of turn. Exile Festering March with three time counters on it. Suspend 3—{2}{B} (Rather than cast this card from your hand, you may pay {2}{B} and exile it with three 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.)
