ok more specifically in response to your questions:
what are you looking for as a way to get in, how are you playing around lazers and using them yourself?
i feel like falco dittos are a super strange matchup because it seems to me that the closer range/minute interactions are super emphasized, so there's a lot of little things to learn
iirc from previous questions about the matchup, PP always says one of the most important things it get your laser out in this matchup
that said, this is one matchup in which going to platforms can be particularly good for falco. usually i'd argue that his horizontal control is so powerful and that even though he has dair, this game rewards being under people moreso than the opposite, but, in this case, if the other falco has control, taking to the platforms can be a good way to reset neutral and allow you to regain your footing on the ground when you're ready to come down. it can be a bit tough to chase falco vertically because his FH is absurdly good so be wary of the other falco trying to catch you with their own bair
know that you can act out of lasers faster than you think too
laser grab/laser shine-grab are great tools for approaching. if they're trying to do the same to you, roll or spotdodge or try to jump away
when you're under the other falco, look to get under him with bairs (which will beat his dairs if spaced correctly), and shine-wavelands. when you're below ~40% you can look to jump up and if they dair (which they often will) you'll hit the ground first and can shine them
How can I abuse Falco's weaknesses with my Falco's strengths and on the other hand how do you not let that happen to yourself?
Think about what falco's weaknesses and strengths are...for me some of the things that stick out are his relatively poor horizontal mobility, great vertical mobility, excellent punish game, and ability to be punished super hard. see how this relates to what i've been saying.
Also how is comboing Falco different to Fox? His tech roll is longer, so do you guys make any different decisions against a Falco than you would against a Fox in order to deal with this?
i usually combo them pretty similarly, gotta be a bit more weary of falco's trying to CC nair approaches (they seem to do it more than foxes). i'd guess higher level falcos than myself know some more intricacies here
There's no Falco matchup discussion in the Matchup thread but maybe it would be a possibility?
I'd love this too, but PP's a busy guy and frankly does more than any of the other top top players to help people out already
