Well, now this card is just annoying. Are you saying that if I play Mitosis, then use it, it'll just get covered up, and I can't use mitosis again till the top one dies? That ruins a large part of the stacking ability for this guy!
hahaha i believe the weapon route would be best then: a stackable permanent placed into the weapons slot. when animated, should it animate into individual creatures or should it animate the top one only?
