Getting around
-counter
-WD OOS
-use platforms
-jump over sometimes. the spacing is sorta weird. if you do it wrong, you'll eat a laser to nair.
-jump over, take the laser, and then throw out a fair anyway
-dash attack if they shoot the lasers too high
-short hop if they shoot the lasers too low
-powershield to WD OOS
-sometimes you can do some sort of far-reaching approach during all their empty laser animations (like dash attack or running ftilt/jab/fsmash)
Making them come to you
-jab or some sort of **** if they approach WITH a laser. if they space the laser too far away from you, they won't be able to link it into anything (not even a shine) before you can hit them with something fast. if they space the laser close to you (so they can link it to a shine), you can jab them before the laser comes out
-jump over the laser to feign an approach, then retreat when they try to attack you
-run up and shield to bait them, then WD OOS backwards into another shield when they try to attack you, then shieldgrab their mis-timed/weakened aerial
-bait them into approaching you, then bust out a lightshield
-dashdance away if they try too approach you. Falco's approach isn't very far reaching. if he overshoots it to hit you, i dunno, just swat him away or something.
random stuff i thought of offhand. there's a little more to it, but that's a good start.
also, i don't think people should think of this as "beating falco's lasers", because any mediocre falco is gonna be using lasers + aerials.
if falco has you cornered with lasers, and he runs in with a nair (spaced so that it will trade with or beat your fair/nair OOS), you can counter, roll behind him, or wd back jab/ftilt/fsmash
i find that if you have falco cornered, you have to still stay patient. if he shoots lasers, don't run in, cuz his nair ***** like, every attack you have while you're moving forward.
