The purpose of this tool is to give users a way to use Random, but only have it choose fighters they're willing to play as, not choose the same one within just a few rouunds,
and also allow them to use the palette of their choosing.
This tool generates randomized set of matchups (rounds) out from user-defined pools of fighters so that each fighter in their pool is chosen once until their pool is emptied,
which would then loop through their pool again.
First, create profiles using the "Add New" button and the text box next to it in the Edit Profiles section. It will create a new profile with what's entered as the username.
Next, select the created profile to start editing it. The Selected/Unused Fighters lists should fill in.
Select fighters from the Unused Fighters column, then click the Add button below it to add fighters to the profile's Selected Fighters list.
Once the profiles have been created, set the profiles on the player column on the table at the top of the page.
Press the Go button to generate matchups.
Press the Single button to generate a single random matchup chosen from each profile's entire pool without affecting the current pools in the mixer.
I'd love for the game to actually have this feature using in-game profiles, but that's not the case so here it is. It'd be really cool if they allowed storing them in amiibo to make it easy to use on a friend's console.
