Weird place to ask this, but I'll give you some tips from a puff mains perspective: Anywhere from 10-40 percent, I am going to be fishing super hard for an up throw rest, a good way to avoid this is to play more reserved, run away and fire lasers at me, and DI if you get grabbed, get use to doing so. On most stages puff dies at around 70-80% from an up-smash, so I will be looking out for it. Also, U-Throw->U-Air isn't a true combo on jiggs when she isn't between 40-90%, and past 70 it is a good bit harder to hit. Fox's that use a lot of dash dancing and lasering are a nightmare for puff, while overly aggressive Fox's are hilariously fun to fight, watch some pro matches to see if there is anything they are doing to avoid certain situations with puff that you are not. Also, asking in the Fox thread may be a good idea.
