Yah I could help you out a bit there. Mostly what I noticed was just that you didn't mix up a lot of approach options very much. You did it quite well occasionally with Jiggs, where you would catch me off-guard with a sideB rather than an Fair, but often if I baited an approach by using an aerial attack (or something like that) you would jump at the opportunity with a generic approach that was easy to read.
Same with Falco; there were several times with Ike where I was able to SHAD through your lasers and then just hold A to Jab and you would initiate a DACUS (or maybe just a DA or something, looked like a DACUS though) and end up eating my Jab combo. I'd have to watch a video on YouTube or something to give a proper critique, I'm not too good at this just doing it from memory, lol.
