Fabricated Skinwalker

Whenever Fabricated Skinwalker becomes a creature, exile target creature that shares a
creature type with it.
{0}: Name a creature type. Fabricated Skinwalker becomes a 4/4 artifact creature with that creature
type. Activate only if Fabricated Skinwalker is not a creature.
Whenever Fabricated Skinwalker deals combat
damage to a player, it stops being a creature and
loses its creature type. Then put a -1/-1 counter
on it.
