Flying

{0}: You may cast target instant or sorcery card
from your graveyard this turn. If that spell doesn't
target a creature you control, it costs {8} more to cast
this way. If that spell would be put into your graveyard, exile it instead. Activate only once each
turn. (You still pay the spell's costs. Timing rules
for the spell still apply.)
