I like how this card has several interesting uses, such as:
The ability to kill 0 atk creatures like Otyugh and Voodoo Doll
Making large creatures such as Armagio more killable
Synergy with Rage Potion and Acceleration
Counter to Maxwell's Demon
Buffing your own creatures
Catapult, maybe?
Synergy with Ball Lightning and Phase Salvager (which may be quite powerful considering you only need
to play Ball Lightning, Equalizer, and Mitosis - and this combo would get even more fun with cards that rely on death effects)
