What a creative display of originality!

Honestly tho', they're rather wordy, but they do seem like alot of fun to play.

Excellent thinking here Arms.

Law #130 of YCM: There's always some game mechanic that has yet to be broken.

You know, it helps if people don't go tl;dr to most card effects, as they miss a lot of detail.
So of course, a few of them had to be wordy in order to generate an interesting effect.

Maybe "Exploitable" would be better instead of "Broken".
