The end of my run through PM2 in which I only upgrade my BP at level-ups (which I have done once before, but that time, I went the Danger Mario direction and it ceased to be a challenge, becoming Super Hilariously Easy. This run was pretty easy too, but not as easy as Danger Mario. I cleared the Pit of 100 Trials midway through Chapter 7 here, after picking up the Feeling Fine badges; in the Danger Mario run, I beat it after recruiting Ms. Mowz, before meeting Bobbery (before I could even reduce Mario's max HP to 5!)... and it was a piece of cake.
Edit: In post-game my BP has hit 99 and I've gone to upgrade FP at level-ups. And reduced Mario's HP to 5, and put on so many Power Rushes that Mario does 99 damage (the maximum) per stomp; there are badges you just don't need when you're Danger Mario, like Power Pluses, Power Bounce, any but one Multibounce, FP Savers... Adding more makes him deal 99 even to enemies with defense, but even when he was doing 31 per stomp it was more than enough to KO almost anything in the game.
Why am I doing this there's not even anything left to fight aaaaaaa
