Every time I see a shine usmash I smile. You need to be more aggressive. You run to the ledge and it looks like you're camping for gimps alot. Needs more overall movement and nair, dair, grab pressure. Try to run in a shield and use WD out of your shield to move forward and progress into your opponents space and pressure them. If you continue running directly to the edge and insist on fighting near it, sooner or later you are going to get cornered because of it. (match 1)
When he ledge lasers jump really high and land on him with bair. If either the weak or strong hit connects he has no double jump and its an easy shine spike. You can also run back a bit and do a full hop nair and land on top of him (going over his high laser in the process). A trick I use alot is: Take the first laser, then shine before the second hits. It works sometimes and catches your opponent off guard. If you notice they aren't doing the SHDL from the edge as soon as they grab it, remember they have no invincibility on it. That being said, you can easily fsmash, jab, or dash attack straight through it. I think even if they do the ledge laser as fast as possible, they'll only be invincible for the start-up of the first laser..then from there its fair game. The problem with that is after the first laser fires it covers the space in front of/below them making punishing impossible. This is how I came up with the idea of coming at them from the air.
The thing that hurt you the most is the failed edge-guards. You got him off the stage WAY too many times. Its okay if you don't kill him everytime, but at least get a grab or usmash on him when he comes back and deal major damage. Alot of the time you'd just assume instead of react and blatently miss predictable guards. Don't run off and dj nair back onto the stage unless you see him double jump back and you TIME IT RIGHT. Almost everytime, you could have just stood there and been patient - then dsmashed. Or you could have turned around and grabbed the edge, then baired. EVERYTIME I TELL YOU. lol You don't grab the edge much to edge-guard, and that took away alot of kills that were simply handed to you.
Watch the video again, and notice how whenever you knock him off CREA double jumps backwards and sweetspots with illusions alot. As soon as he double jumps backwards and aligns himself, he makes what he plans on doing insanely obvious. Because he is so far away, its easy to react and cover his now limited options. Seriously, grabbing the edge and bairing, or just holding it, would have worked wonders. IMO the best way to edge-guard as Fox is to just stand there with your back turned. If you see him align himself dsmash or FF edge-hog. If you see him go high simply bair. If you see him firebird, grab the edge and bair him. If he illusions straight at you utilt and bair. Keeping your back turned towards the edge is so broken. lol
But I digress.
I'm pretty sure you know all this already, but just didn't do it in tourny play for whatever reason. Nerves maybe? In any case, good luck and post more vids. Work on that edge-guarding! Don't guess, don't assume. THINK AND REACT.
