Where can I find one?

We actually don't have a complete one right now. One of the best places to find that info by individual cards is http://twoheadeddragon.com/ufs/index.html

Supposedly they are working on one for when set 12 comes out, but till then, all the bans and erratas are in the individual State of the Games.

ok thanks. I really hope they release one soon. It is hard to remember all of them.
