Match two:
You immediately double laser hi-lo, which would have stopped a running or a fh nair approach. he runs into shield, which is a good start for you.
:06 you run up and dair far enough away to not get punished. he could have WD'd back and grabbed, but he was probably expecting another laser, so he jumps instead. while it doesn't connect, you're in a perfectly fine position. When you don't hit, you shield and roll backwards and get back into position.
:07 another hi-lo laser, which he manages to dodge but stops him from getting close enough to attack you. You follow this up with a running shl (unlike last time), which he shields. You now have him in his shield just out of grab range, which is a good place for you.
He actually jumps out into your dair, which works out well for you, but the dair would have been an appropriate follow up either way. His shield comes out before your shine, you shield pressure tidily and he gets away. I like the retreating nair at the end, although he doesn't actually fall for the bait and rolls instead.
:10 you roll backwards here, which I don't think was the best choice. Perhaps you didnt intend to be in shield and this was meant to be a dash. Rolling gives him the opportunity to get up to you while you're relatively helpless, and as you're jumping up to try another laser, he hits you (with a fair that I assume was meant to be a nair). After you rolled and saw him coming at you, I would have advised either a CC if you think he's likely to nair, a retreating laser or WD backwards or something if you think he'll attack where you were standing, or a shield or something if you think he'll go past/you're not sure. that's a trickier situation.
at :13, after some sloppiness by both players, you see an opportunity and dash attack. Fox is at very low % at this point, so a dash attack is not a safe option, but at least you went for the opening. After it hits and you realize he's going to have time to get to you, you try to utilt to out prioritize his move. I know some disagree, but my opinion is you shouldn't try to out prioritize moves (at least not in this matchup) except sort of as a desperation tactic. It makes sense if you were expecting him to run up and grab you or maybe even dash attack you. A CC shine might have been a better option, except that would have gotten owned by grab. overall not a bad decision, but one that doesn't work out for you.
He lands the weak bair, and then dash dances away and back into grab. he's baiting a spot dodge and you don't fall for it, rolling in instead.
At :15 your roll has ended. You're in almost a neutral position except he has a little lag left from the grab. You choose to play it aggressively, and you run in and attack. Against your opponent, this worked out, because he doesn't usually respond accurately to shield pressure, but in that situation against a strong opponent, you don't really have enough time to consider it an opening. I would have recommended lasering, or running partway forward and seeing what they do (eg if they dodge or stay in shield you can punish, or you can WD back laser or something, since you do have the initiative here). Capitalizing on the small moment you have is good, though, in any case.
Im not really sure what happens around the skip in the video.
:19 he's just rolled and is standing behind you, facing you. You FH dair his shield and after a moment get punished like you should; throwing a full hop aerial on a shield is not a safe option.
:20 he does about the same thing to you, haha. he fh bairs your shield. or tries to; you dodge it. i dont think the dodge lasts long enough to make it safe if he shines after he lands, but i could be wrong, and in either case he didnt. you shine and jump up and bair.
I'm not sure how I feel about the bair. It was pretty sure to work, which means it's at least a safe option. He was at 32% before the shine, so you weren't going to get another dair shine in. you could have gone for the bair and then tech chased, but that's not a guarantee. shine->WD->uair or shine->wd->nair->followup might have done more damage, but in that situation you just wanted to make sure he got off your back, so the bair was a good choice.
:22 he techs. You're not close enough to punish it. you WD backwards and then run in with a nair. This would have been the appropriate punishment if he had dodged, but he didn't. It was a good guess though, since he seems to fall back on dodging sometimes under pressure. In this situation, I think you had two real choices: go for some tricky kind of bait and punishment like you did, or just laser and try to keep him cornered with his back to the edge. that situation is lower risk but also harder to convert to a winning position, so either one was worth trying.
Anyway, he happens to out predict you, so you whiff a nair and get drilled. You DI the dair backwards and don't get shined, and land in shield. You're not in a good position. You choose to roll backwards. As it happened, it looks like you could have gotten a grab, but if he had sh naired you it would have been bad. he predicts the roll backwards but messes up the spacing or else you would have eaten an usmash or a grab.
around :25 you FH bair into DJ bair, which you also did in match one. he punishes it easily (although not severely); I'm just reminding you this is a risky habit to be in.
:28-:31 you get in a nice combo and read his tech in place correctly. good call on uair instead of bair; he DIs it wrong and eats more hits. you also follow up well with laser, which turns out to cover his roll left option perfectly, and was the only thing that would have caught his other options anyway, into grab dthrow dsmash for the kill. nice ending to the stock.
The rest of the match continues in the same vein. You're both rolling and dodging too much, but you're calling each other on it and punishing a decent amount of the time. I'll just point out a few things
at 1:27 you do a well-placed hi-lo laser. However, after it's over, he's closed the distance to you a lot, despite having been stopped with the low laser. He's far too close to you for another idj laser to be safe. A SHL would probably have worked, a retreating RSHL would have worked but put you too close to the edge... I'm not sure. I would probably have SHL'd or SH naired or something, but I'm not good enough to tell you the best option there.
1:40 you've got him cornered and you let him back out. you should try to pay attention to when you've got stage control and try to milk it. he has nowhere to go as long as you're between him and the middle of the stage, so you get to limit his decisions and thus he's easier to punish. Try to take advantage of it, and if you're going to surrender it it should be to bait an opening. This is one of the hardest things in smash, I think - for me at least - but also something you should really try to keep in mind.
Laser control around 2:00 was nice, and would have worked out if you had gotten the second one a little lower. That was a technical error, not a strategic one. Unless you meant for the second laser to stay high to punish a sh approach, in which case it was still a reasonable decision that just got outpredicted.
at 2:13 after a little combo, he hits the ground and you predict a tech left and run over with a dair. It misses, but that's not the point. I personally frequently predict my opponents correctly, hesitate, and don't have time to punish. the fact that you're confident and go over and throw the move means that as your predictions improve, you'll land more of the punishes you've earned, which is good. besides, you dont get punished for it at all, and couldn't have, really.
Lovely laser reset -> dsmash finish.
You gave Gin openings because your nerves kept making you roll and dodge and such, but you also took a lot of the ones he gave you, which is important. when you had stage control you capitalized on it sometimes and missed opportunities other times, just try to take more of what's given to you in the future.
