Hello, it's been a while!
After a very lengthy trip through hell (AKA burnout caused by poor API documentation and other things), the Classic leaderboard is finally here!
Now this screen is slightly less empty!
Unlike the Classic (No Mutators) leaderboard, the Classic leaderboard lets you set a high score using any mutators you want (except for Training Mode). You can click the handy button next to the "Mutators" label to see what wacky combinations people have cooked up:

And by "cooked up", I mean randomly selecting a few to check if this feature even worked.
Just like the other leaderboards, if you think you can do a better job than whoever you're looking at, you can Challenge them to copy their run settings, Mutators included.
For a refresher on how Challenges work, check out this announcement I don't even remember writing!
I've already seen people rack up absurd high scores offline with certain Mutator combinations, and I expect people to do the same for that #1 spot online. Good luck!
