Not bad to do that well against Mango, good stuff duck lol
I'll go through an unordered list of observations I guess
Falcon's nair and knee approach gets stuffed hard by utilt. You hit him once with it but you started late and you traded. utilt is just nice because it makes the falcon a little more skittish on his approach to you and it's easier to keep your stage positioning rather than get pushed to platforms, which samus has a distinct disadvantage on. Basically it just keeps everything on the ground longer
Mango kept baiting your dsmash on his shield and punished you in kind of nasty ways.
I actually use dtilt rather than dsmash as a personal preference, mostly against fastfallers. The two moves are almost identical down to the frame, but dtilt actually has less ending lag (only by a few frames), plus it leads more consistently into extra followups with aerials or fsmash, platform followups, which you're really good at, etc.
Though it's probably not reccommended to use either against his shield.
Those were some nice grabs on first match lol
You stopped going for them after game one though :C
uair is actually really nice against falcon if he's positioned himself over you in the air. It's one of those moves that's a lot larger than it looks, it has a fast startup, pokes great, and has virtually no landing lag. Falcon is really momentum based and even if utilt doesn't lead to anything through hit-confirm, you can usually startle the falcon into reacting in someway, probably with a shield. At the very worst, it screws with their timing.
Same with jabs and jab cancels. You were throwing out a lot of double jabs, which against falcon is actually surprisingly good at setting up edgeguards, but he was just shielding in between jabs and then taking full advantage of his frame advantage over you. I think you should add jab cancelling to your arsenal, falcon doesn't have much oos that's fast enough to take advantage of properly spaced jab>jab>wd back ftilt mixups
also yeah sheik >_>
her shield comes out too fast, everything combos into everything, and the best way to get a surefire hit/followup is with a super risk move (grab)
well you were edgeguarding properly
and reacting properly
You might have been leaving yourself a bit too open by not staying grounded here and there
I think it was a timing issue for you in that match. imo you just need a bit of tweaking to be more effective, as lame and unhelpful as that sounds, but that's all I got lol
