1. Keep your Tori relaxed. This makes your moves flow easier and also have more power.That's all I got, I tried :^)
2. You can and should keep editing the replays until you get it perfect. I can never manage to do this.
3. Get a good-looking Toribash set, or make a custom one using a custom folder. This might help a smidge, because you look _pro, _bro!
