Tips on fighting against Fox and a general overiview of how he plays? Haven't played as or against him very much until only recently where I met 2 really good Foxes in my scene, and got totally destroyed by one in my last tournament due to my low experience with him and not knowing what to do? I know he's a lightweight fast-faller with crazy combos and fast speed, but what else is there to know?
I play

,

if it matters
Two big things I take advantage of a lot are characters that try to land back on the stage, or characters that respect Fox's smash endlag too much due to unfamiliarity with Fox.
If you're in the air, you should always make it a priority to recover onto the ledge, rather than landing on stage. Fox's frametraps on stage are bonkers, but offstage, Fox has weak options and his ledgetraps aren't great.
When you're at kill percents, you can sit in shield a lot. Fox has poor throw followups after mid percents, and no kill throws. The worst you'll eat is ~7% chip damage and a reset to neutral. Fox also has very unsafe kill options on shield.
I'd also keep rolling to a minimum in this match. Fox has solid options for characters who roll into him, and even a roll away can lead into free DA followups or a running usmash.
