Alright I only had time to watch the falco ones because I have to get ready for pound since I'm leaving in a few hours LOL
Here are some things I noticed:
I used to love the falco matchup. Then Chops moved over here and I realized how difficult it is. Really good falco players (like G$ and Chops) will tend to crouch cancel your nairs up until like 80% so you're going to have to use dair shine or just shine a lot more when you approach.
Your combos/tech chases/follow ups are good. On FD, you should be chain grabbing a lot more because that's what it comes down to at high level play.
Also, waveshining in place against his shield shouldn't work. He can shine oos or just shield grab you very easily. Learn how to double shine. It's extremely useful in any matchup, but especially versus falco because you can use it two ways.
One, if you get a grab on the edge and they don't DI it, you can double shine them and then either grab the ledge or jump off and shine his up b since it's extremely easy to shine falco's up b. Jman does it a lot, watch his match versus PP.
Two, if you approach with nair and the opponent shields, you can double shine instead of nair shine and if he goes for a shield grab he will get shined and knocked down. Then you can tech chase into another shine or grab or whatever.
That's about everything. Good luck.
