One question is there anything new that I should know about since I have been away for a while
Don't remember exactly how Fox was played around the time you started to play less but some things you should do (unless you already do it).
-Shine OOS into waveland. I basically have only seen 2 Fox mains use this kinda often and it is very good (especilly vs Falco). Might be a bit tricky timeing but learn how to do it consistently and you will have a much easier time.
- u-tilts: Most underrated move Fox has. After a long Nair combo across the stage it can be very good to mix in with a u-tilt instead of uppsmash. Cause the correct DI for u-tilt is the bad DI for uppsmash (on killing % at least). One pretty funny thing i have noticied with this move (mostly vs Sheik) is that if you are about to edgeguard someone (Sheik) and they land with their upp-b on the stage and you go up to punish them u-tilt is pretty good.
The player will in basically all cases as long as they are not experienced against it at least, DI super bad. Cause if they have survival DI they go RIGHT upp from the u-tilt and that gives you a free uair and it works until higher damage with a plattform of course. Also can be good on medium % to kick in with a bair or two after the u-tilt. If they DI the other direction they fly VERY far off stage giving you a free edgeguard. But yeah when you use this you should be the one closest to the ledge and the Sheik (or another char) should be close to the center of the stage then you.
-Second hit only with uair: This is kinda old but also something only 2-3 Foxes use consistently
- Shield drops improve your movement from beging deffensive to offensive super fast. And from the days when I played you I remember you could stay a bit more deffensive and then go in when you knew you would benefit from it. I do think you are one of the Foxes that can benefit most from this technique.
That's some stuff on top of my head. Good luck at EVO man =)
EDIT: Yeah run up with shield is very underrated and something I also used while I played this game. I do think overall people has been overrating some aspects of the game and staying in shield is not that bad. From shield you also have the chance to change your movement and grab is the only thing that truley counter it
