hahaha. nice idea. i approve it, simply because its physics related^^
reminds me of this:
http://zs1.smbc-comics.com/comics/20100424.gifbut seriously, it doesnt seem too powerful. doesnt have too much hp, and also the ability cost is allright. i like it.
PS: the ability should really read:
observe: schrödingers cat is either dead or alive.
dont forget to mention, that you can only have two unupped cats at the same time in play and that you can only use the ability of one cat per round, because if one is dead, the other has to be alive
the upgraded version doesnt have these limitations of course^^
this gives me ideas XD
(just to clarify, this is a joke
)
