Good games Chreest. Wifi kept taking dumps on Charizard's recovery, so I SDed at stupid low percents. I think Samus did alright though.
Work on your banana control, and use more jabs and tilts with Diddy, as well as pivot grabs. As for Falco, it isn't necessary to use Reflector so much against Samus, since you're just going to get punished for it once it comes out if I don't fire anything. I'm not likely to fire Charge Shot immediately after charging it up, and a competent Samus knows not to use many projectiles in that MU unless they're looking for reads or setups. You can jab to negate baby charge shots and light missiles, and can pretty much reflect everything else without worry. All you need to worry about is out-camping Samus as she can't get anything out against Falco's lasers save for a z-air or two, but she still has to make halfhearted approaches and play super patiently. Falco devastates her up close, ideally. The only reason I stood a chance was because I could read how you were playing and punished a lot of your dodges, multi-jabs, and reflectors.
Jabs 1 and 2 are good enough on their own for setting up lots and stopping punishes, the multi-jab should be used much less often because it's really punishable out of shield. Your out of shield play was pretty decent, but far too inconsistent to be effective. Make more use of your aerials, particularly b-air, n-air, and d-air out of shield. And stop using ledgehopped f-air. It serves almost zero purpose save for putting you into the same bad position (on the ledge) or a WORSE position (on the ground, full landing lag from either the aerial or your post-recovery landing lag). If your opponent is near the ledge, stall some or ledgehop n-air, d-air, or phantasm. If they're some distance away, ledgehop single laser onto the stage,
