Body Switching Rivals

I'm going to intentionally leave this one a bit open ended and easily approachable. Hoping for community involvement.

The curse of the body switching rivals is a nasty one indeed.

In order for it to work, generally both targets must be extremely competatively tied to tearing down each other. Two directions of true spite were ideal.

So which bitter rivaly is about to get flipped?

Will they be too busy embarrassing each other to work together?

Or is it a lesser spell only taking control for a few minutes or hours?

P.S. I'd love to do a version where reach rival is written by someone else. If anyone would like to pair up on that shoot me a message/feel free to start us off.
