You guys really need to get your percentages down a bit more
I mean, I understand it's tempting to dash attack when you get a clean one but at like 14 or 10 or less than 20 that's not even going to knock them down even if they don't CC it
And in that case it's strictly 100% better to grab
Slhoka (Falcon set)
1) Stop full jumping vs Falcon. I see this Falcon is terrible and an idiot and nobody's explained to him that his Uair defeats everything. When the day comes that he realizes all manner of FJs lose to him SH Uairing under them with his blistering speed, then all your full jumps become useless. It's better to be grounded vs Falcon anyway. CC, duck, and shield dash are annoying for him.
2) Don't get so antsy with your dash attacks. Like, seriously. Chillax. He's baiting you and blocking a lot. Grab him. Or just walk forward and let him corner himself. Or don't commit heavily and just move around. Relax dude.
3) Make better combo decisions... prioritize hitting U-tilt, Uair, and Dair above most other moves in a combo if they're available as options. Obviously if your only guaranteed follow is to F-tilt or Dash Attack then that's fine just do it but if they pop up directly above you then the three I listed are usually better than anything else you have if you want to rack a good percent and lead into a finisher. Dair is probably the best if you can actually hit it.
4) Grab edge --> Bair / other aerials is better than D-smash edgeguard at high percents. Grab the edge if you have the option. Your edgeguarding vs Falcon is actually fairly good. Europe is actually fairly good about edgeguarding and gimps.
5) Don't play around on platforms vs Falcon. Again this guy is awful so he doesn't seem to understand how to combo Sheik or how to put pressure on her when she does something wrong but I assure you that platforms are not something you want to be on vs him. They might seem like a good idea because your aerials are long and they give you another avenue to do them from, plus needles, but he's fast enough to maneuver around both of those, get under you, and make you miserable.
6) Learn how to do the easymode dash attack tech chase. When you hit them away from you with a tilt or whatever just dash, stop a little bit in front of them, if you see them bounce (non-tech) or tech stand just dash attack them, if they roll into you just dd dash attack them or U-smash, if they roll away just run for a while and dash attack them (or boost grab if you're feeling slower since they probably block).
7) I don't approve of guess tech chasing but I'm tragically guilty of it. Still, some of these situations you really do have enough to mindlessly F-tilt/D-smash/dash attack whatever he does. Especially when you trap him near the edge because of the throw's trajectory.
8) I'm going to guess you thought he was dead on DL64 when you let him onstage. For future reference, Dair is a better move in that situation than Fair unless they're at about 150% or so.
Yeah that's pretty much all I can tell
