For RBY & Tradebacks Formats, you're in the right place.
For Stadium Format, go here.

So I've worked on it a lot recently and I daresay it's done. The current ladder is not tagged as beta and has a lot of bugfixes and refactors. I must ask of you, dear smogoners, to play gen 1 (challenge will suffice) and tell me if you find anything wrong.

Thanks!

Edit: You have now play gen 1 with tradebacks as a challenge option as well.
