More critique for Arc:
vs Falco (WF and GF):
You do a lot of fthrows. In some cases I can see the reasoning behind it (like when you fthrow -> dtilt to get him off stage), but what's the point of doing fthrow -> techase regrab -> upthrow at mid percents when you're in the middle of the stage ? Why take the risk of tech chasing when you could just upthrow immediately? Maybe you were looking for an improved position to upthrow from, but when he teched towards you you ended up in the same exact spot as before the fthrow, so all it accomplished was a negligible amount of damage.
In my opinion, fthrow is only worth doing when you're aiming for something particularly good out of it (like an edgeguard, or a techchase -> fsmash/reverse up-B)***. Something better than what you could get out of an upthrow in that particular situation. If you're going for something that you could've gotten out of an upthrow as well, or something that's not really that much better than what upthrow would accomplish, you're basically just jeopardizing the entire combo for no good reason.
***Not a huge fan of it in those situations either, but at least it gives you a potentially better follow-up.
You occasionally do that thing in the neutral game where you jump on a side platform and try to catch Falco's approach with a falling aerial. I used to like that a lot as a mix-up, but with a solid PS game (which is something you have) I don't see any real gain from it anymore because at its core, it's basically just a substitute for powershielding (since lasers are the only real reason you'd even want to consider going up on a platform against a grounded Falco). That, combined with the slight hesitation after most of your dash away powershields that I mentioned earlier, gives me the impression that you're not completely trusting your own PS game. Which is completely understandable; landing them consistently while at the same time not spacing like a turd requires focus, so it might feel tempting to have a bit of a plan B to fall back on, but ideally you want to aim for a point where PSing is so integrated into your mind that you don't have to think about it any more than l-cancelling or wavedashing.
You also need to expand your PS game beyond dash away PS. It's a very solid start, but eventually becomes manageable for Falco as he learns how to deal with it. Start working on ducking PS, standing PS and walk forward PS as well. Dash forward PS is by far the most rewarding, but unfortunately also the most difficult to land (the drawback of dash away PS being easy) so that one's optional.
I think your punishment game would improve if you started to look for upairs more often (you started doing that more in GF, though). Especially when you've put him on a side platform.
I also think you're a bit quick to go for the uptilt sometimes (when he's at 20-ish %). If he doesn't DI to a platform, just keep regrabbing him. If he does, a well timed uair (uptilt in some cases) will cover all options. Uptilt -> questionable tech chase is a bit sub-optimal next to those options.
Your edgeguarding is a bit inconsistent. Sometimes you're looking like M2K, and sometimes you're making things way too complicated for yourself. In general, I think you could be a little more aggressive with fairs. Falco should be afraid of using up-B when he's close to the stage, but for the most part he doesn't really have a reason to in these matches. Fair is just great overall when he's above the ledge.
A little more WD OOS when he's close and trying to pressure you probably wouldn't hurt.
