What do you guys think about this Its non mandatory. 

Each participant in a battle chooses one of the following for it:

Type(Normal, Powered, God)
Location
Stiipulation 

For instance. 

IN vs Blades with me as a judge

IN picks Powered fight. 
Blades picks Tilted Tower as location
I stipulate both fighters wear a collar that injects them with a increasingly stronger sedative whenever they use their powers
