Corrupting Evil

Target creature you control gains shadow form,
then deals 5 damage to each other creature.
(Whenever a creature with shadow form destroys a creature, exile that creature under the one with shadow
form. When the creature with shadow form dies,
return all creatures exiled with it to their owners hand.)
"It's too late. I can no longer be a hero like you, even
if I wanted to. I'm a horrible duck, but its too late to
change." — the Iron Duck to his father.
