1. Have fun!
2. Do what it takes to win, within reason.
3. Using hacked movesets is an instant ban. If your opponent delivers proof of you doing so (with a capture card or something similar) you are gone.
4. If you can do it legitimately in-game, do it. Win on a random submission, a finisher, a hip toss, or a chairshot (after knocking the referee out, of course!).
5. With running no longer infinite, runspam isn't a real option anymore. So don't worry about runspam, run as much as you want for as long as you can.
Any other rules you would like to see be added, please just speak your mind.
