played a lot of falco recently, struggled a lot vs him too. barely jabbed approaches and i was always trying to shield grab punish. got a lot to work on, even my movement was lacking too.
i'm not gonna do a play by play critique or anything, but vs falco you really need to get a lot off of your grabs and that never really happened vs either of those falcos. you shouldn't be trying to dthrow cg at 0 imo unless you're 100% proficient at it, which no ganondorf is. go for the dthrow jab pseudo-cg even if you're trying to get your cg fix lol
you need to focus on spacing more. if you fair falco you should NEVER be getting shield grabbed. that move goes so far out and you gotta take advantage of that. every fair i saw you do vs cyan was like inside the dude's shield, don't do that
your shield grabs on these falcos were way too telegraphed, and every time you did one, it either got you killed or you ended up taking a bunch of damage for it. no good. mix up the stuff you're doing out of shield. also learn to di away in shield when you're going for shield grabs. it's essential imo.
walling out falco is extremely important because once you let them get out of the corner, that gives them a chance to get back on their feet and control the stage again. you need to make sure that when you've got them in the corner that they either don't get out, or that when they do get out, they're put into a bad position (ie, making them go to the platform).
