Hai...this thread is basically the opposite of The Pairing Thread (how original am I?)
Basically, the point is that you post rivals. So, keep it like
[name] x [name]
Anyone you're really competitive with or just have a rivalry with, you can post!
Idea is, you repost the above poster's post..that is, copy and paste, then add your rival underneath. Don't kill the order of rivals.
