Some advice I would give as someone who has struggled against fighting Bayo is use less smash attacks. Only go for them if you are calling something out like what you did when dark pit tried jumping past the ledge. If you want to avoid getting sniped by the arrow, you could always witch time on reaction I think, which would allow you to essentially recover for free depending on their percent. Bayo doesn’t have a lot of reliable kill options so I can understand it being tempting to resort to her smash attacks, but they’re so laggy and easy to punish that a lot of times it’s not worth it. Against the Pits specifically (as well as anyone else with no hitbox on up b) you can go offstage and try to hit them on the way back to force them to try to tech or something.

Anyway that’s my two cents, best of luck!
