Longdead Wyvern

Flying
Suspend 3 - {3}{r} (Rather than cast this card from your hand, you may pay {3}{r} 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.)
When Longdead Wyvern enters the battlefield from exile, put two +1/+1 counters on Longdead Wyvern.
