As a result of your GMT predecimant, i have thought of a solution:
Why not have a bracket tourney,
1v1 fights,
The fights (Who fights who) organized by you or somebody on behalf of Plasma
the times organized by the players themselves
Winner gets the toxic primary grad and half all entry price
I'll provide a prize for second place
^^Brief idea, if you go with this idea i will iron out the specifics
