Sorry I've been neglecting this thread for the past few weeks. I've been pretty bogged down with school, but I've attended three more tournaments since I made the thread and tried some of these suggestions and also played around in the lab a bit. Once again, thank you all. Thanks to advice from this thread, I've found that a lot of Fox's kills should be coming from pressuring or just waiting for the opponent to make a mistake, and then punishing it, rather than trying to force it, like I was before.
^ upthrow to get them up above you for uairs can work, but from my experience most good players know that against fox you dont try land on the stage, you go out and around, over the edge and back to the ledge, fox cant chase offstage both due to having no horizontal air speed to catch up, and no great offstage options, so most good players will just do that after an uthrow.
I've found I've had to really focus on getting good and punishing people trying to get up off the ledge, since fox can put people there very very easily. Hard thing to get good at though, still trying to iron it out.
Yeah, I've found that up throw is pretty good against players that aren't as good as me. All I have to do is up throw, read (or react to, in some cases, like some heavyweights) how they land, and that's a stock. Like you said, though, good players tend to go to the ledge after they get uthrown, so that doesn't work too well against them.
As for punishing get ups, I've practiced that quite a good deal over the last two weeks. Two things I like to do are to up-B into the stage as they get up, which covers every option but jump, and to shield on the ledge, punish normal get ups and get up attacks with grabs or Usmash OoS, and then just run up Usmash on reaction to a roll.
Auto cancel bair on shield is absolutely amazing with Fox. With the new shield stun auto cancel bair on shield gives the opponent 10 frames of shieldstun while you can then walk away lagless. Maybe even turn around grab since grab is 7 frames.
Just like you and some other posters suggested, I've been trying to work spaced bairs into my game. It really is a great pressure option on shield, especially since the 1.1.1 patch. I never thought about doing it into grab though, thanks for the tip. :]
...Is this really a thing?
Firefox in general. Favorite kill move right there.
I've found Firefox decent to cover ledge getups, but how could I use it as an outright kill move without the read of the century?
