Morrigan, Dark Enchantress

At the beginning of your upkeep, you may exile a creature card from a graveyard. If you do, create
a 2/2 black Zombie creature token.
{b}{b}: Whenever Morrigan deals combat damage
to a player this turn, you may destroy target
nonland permanent that player controls.
The whispers of the shadows guide my hand, and the
curses of the ancient ones fuel my power.
