Ysera, Shadowflame Mistress

Whenever a creature you control deals combat
damage to a player, you may exile target creature
card from a graveyard. You may cast that
creature from exile for as long as it remains there.
{1}{u/b}: Return target creature card from your
graveyard to your hand.

She commands both the fiery power of
destruction and the elusive nature of the
shadows, binding them to her will.
