I FUCKING GOT IT!
A quick draw competition. A FUCKING QUICK DRAW COMPETITION! How genius is that? (Very genius was the right answer).
How does it work? An admin stands between two players. He shouts out a spell (not sure what else it'd work with), and the players both hit him with it. First one to hit him wins.
It'd be like a pvp bracket.
Only potential problem is some people may not have magery...but fuck them
A quick draw competition. How the fuck do I come up with this stuff?
