Falco is such a frustrating match up... I know how you feel... those lasers are the most annoying thing on the planet and Imo falco is more BS than meta knight. You just have to learn how to deal with the lasers.
Any every falco at my skill level or lower will do this:
Spam lasers
if you shield
they laser approach and try to grab or tech skill you
if you approach they laser you and follow up
or
spam tech skill
in which case you either up-b, grab, wavedash away, or up-b cancel out of it, maybe even n-air or up-air out of shield
Answer:
at least what I have so far is pick a stage with platforms and use the platforms to get around the lasers... doc's platform movement and spacing game is really good and you should abuse it as much as possible
For me personally, i feel very comfortable on yoshi's story because of the way the paltforms are spaced, I feel they perfectly compliment doc's movement. I usually try to take falco to either yoshi's, pokemon, or dreamland. For captain falcon I wouldn't know... I imagine the same thing would apply but maybe different stages.
You'll learn the match up over time. They more you play the better you'll get at it. That's why I'm very knowledgeable about the Marth match up because I've played against Marth at least 1,000 times.
