That seems like it would be a bit overpowered.
However I would love to see users use it in a deck with SoFree, and then fail to realize that they can't target their own air creatures. >.<
edit: I know I didn't read much into the post, but does it replace the creatures skill? Like a butterfly effect-esque lobotomize? If so, then maybe it wouldn't be overpowered, cus it would get rid of dive, a powerful
skill that might not be worth it to replace. Or its own skill even.
double edit: looking back, this isn't mentioned. 0.o Is bounce an active skill?
