I don't get it. maybe in some odd malignant cell deck it might be handy, but bond decks are dead by sofo atm
and this wouldn't be all that great with them. being able to use the abilities of a killed monster though is incredibly OP depending on the skill. what about any mitosis'd? or a mutated thing with a 0 cost mitosis 15|2 fire guy or something. or even arctic squids. come on that has to be OP, some immaterial arctic squid crap. also broken with soP which allows you to add attack to your 0 attack guys. in the case of a water stall for example.
so it's really UP for aether, and OP in water stalls. waste of a possibly helpful to aether, aether card, and buffs the already hated water stalls
you give too much credit to the undead
