Nighthawk, Rasputin's Pupil

{b/r}: Target creature gets +1/-1 until end of turn
{2}{u/r}: Target instant or sorcery card in your
graveyard gains flashback until end of turn. If a
spell is cast this way it gains overload and "At
the end of turn, sacrifice a permanent if no
creature died this turn."
{3}{u/b}: Mill 7, return up to one permanent card
milled this way to your hand.
