i'm not reviewing you vs armada because i want to go outside sometime in the next month lol
i'll come back and look at everything more closely later tonight.
edit: you would pick a falco mix-up. i'm a little soft on falco knowledge in part because i don't play falco, in part because he's so stupid complex, and in part because falco is poopy and stupid. i'll try it anyway.
typically when falco is pinned by the edge, his first goal is to get to a point where his dash can do something meaningful to reestablish position. falco has a "hole" per se where his moves are considerably worse when he can't place them exactly where he wants to (as opposed to sheik or samus or a similar character). to me it makes total sense that mango's first action is to dash out of the corner to regain stage. so it becomes your job to disallow him to gain raw stage area back. how falco can do this is highly varied and here's where i'll start to look like a dip****.
mango's first action is to dash immediately to get out of a positional disadvantage. at this point, you already have positional advantage by holding center stage while being close to him. this effectively walls him out by keeping him at the edge and forcing him to get past you to reset to neutral. at your position, he does not have enough space to make proper use of falco's dash, nor does he have a good point to jump to coming out from the edge until he gets closer to the center stage where full jumping to the top platform offers a way to reset to neutral.
at this point, mango has retained enough stage to where he can transition back into the neutral game if you fail to check his movement, so he stops and shields, shield-angling in a buffer toward you to cover your low-risk options pre-preemptively. this is a good, safe way to regain raw stage area to lessen your stage control with minimal risk. if you fail to check him here, he has a few decent ways to reestablish neutral, by the aforementioned jumping to the top platform, or by reacting to any mistakes you give him. since you don't give him anything to work with-
he opts for what is clearly the full jump option to the top platform. at this point though, you still have positional advantage from your dashdance, so even if you didn't laser to keep him pinned near the edge, his options are still fairly limited in terms of actually dealing with you. you haven't really given him anything to work with except a small portion of the stage where he's still disadvantaged, and you also haven't extended into him under the platform where he could have had another opportunity to play around with your extension and maybe leverage a conversion out of that.
the final result is that you stuffed the move, although at this point the bair isn't really a mix-up but just going through the motions since mango's next move is clearly the jump. the real mix-up of this movement was your initial dashdance out of the tech roll by not extending into the other falco dashing in towards you.
there's 2 caveats here that follow my initial argument. first, even if this is a mix-up, you maintain positional advantage for the duration of the entire maneuver. this makes your stage coverage very low-risk and mango is actually has very few ways to meaningfully interact with you. secondly, i'm not necessarily convinced that this movement is strictly subpar. this may be my lack of experience and knowledge with falco, but the point stands that the alternative of lasering and closing in is questionably another way to over-extend into an opponent that was frankly ready for it if you did it- dashing at you, ready to react to your coverage, and experienced at shield angling and shine oos conversions from that kind of play. you'll have to explain to me why it's subpar, because the two alternatives seem fairly closely matched if not in favor of the "subpar" decision. again, i'm not a falco guru.
