Okay hear me out. Let's pull a Melee, Brawl, and Smash 4 and make hundreds of trinkets that you can buy and get from challenges and whatnot. We could probably use cloud variables to track which account has what trophies, and there should be a reset button for whenever you want to start over the trophy collection. Wouldn't that be neat? I could code it (if I figure out how) The only challenge is getting ideas for trinkets, but it's something to think about.
