Spire Canyon Stalker

Flying
Mount — {u}{r}, {t}: Until end of turn, target
creature you control gains flying and whenever it
deals combat damage to a player, you may cast
target instant or sorcery card with converted
mana cost 3 or less from your graveyard. If that
spell would be put into your graveyard this turn,
exile it instead.
All that's lost is mine. —Salti
