Fiendfire Mage

Flash
When Fiendfire Mage enters the battlefield, you
may cast target instant or sorcery with converted
mana cost 2 or less from your graveyard without
paying its mana cost. If Fiendfire Mage was unearthed, that spell must have converted mana
cost 1 or less instead. If that spell would be put
into your graveyard this turn, exile it instead.
