Wunderwaffe DG-2

As the Wunderwaffe DG-2 enters the battlefield, attach it to a creature you control if any opponent controls a zombie.

If any creature is dealt damage by equipped creature, put a stun counter on all creatures it's owner controls. Any creature that was given a stun counter this way takes 1 damage at the beginning of
it's owners next upkeep.
