Falco Advice by Esca
Stage Selection is so important. Make sure to strike FD, you don't want the Falco to be able to run so much. YI is decent if you like it enough, and strike Battlefield too. I think Smashville is Pit's best stage against Falco. There's alot of undeveloped grab combos and other move exploits on that moving platform. Pokemon Stadium 1 is also a really good stage for Pit, because of the stage transitions. Falco has trouble on a couple of them, and if you know how to use them it can benefit you well.
Get That Grab!
We all know Falco can chaingrab us, so we need to avoid being grabbed, which is a role switch, because Falco is usually having to avoid grabs. Don't forget that you can also grab him! You can fthrow>fthrow> stutterstepped fsmash for 39%! That's just as good as his if you stay by the ledge. The best way I find to grab Falco's is baiting them to grab me, and pivot grabbing. Find a platform and dair camp him post-grab, he has trouble with that. Treat him like the furry he is.
Smashes
are so vital against Falco. I find Falco to be one of the few characters I can abuse smashes with. Dsmash is so good because of how fast it comes out, and if Falco is below 25%, you can combo with Dsmash. If you hit Falco with the second hit of your dsmash, you can fsmash him right after at low %'s. Fsmash is again, good to save for kills against Falco, since he's fat and it's hard for him to DI it. Try to get the Falco to side-b. If you learn how to bait them to side-b, you can get pretty free kills. I typically try not to use Usmash too much against Falco, as it's punishable from the sides. However, utilt is a different story.
Utilt
is such a good move it needed it's own section. It's our fastest move. Falco is such a ground based character, that a fast grounded move is so useful against him. It outprioritizes his sideb/upb/fsmash/ steps over his dsmash, you get the picture. Use it when he has to phantasm (side-b) back to the stage and it's free damage. Out of shield it's so helpful against Falco because he usually boxes. It's also an anti-air move if their above you. Use this!!
Angel Ring and Mirror Sheild
Normally I'm against using side-b against characters, but against Falco it's really helpful. It reflects his lasers, and beats most of his approaches oddly enough. It's hard(er) for him to DI out of it because of his weight, and can rack up damage quite nicely. You can fall off the stage using angel ring on a falco that's trying to up b back for the gimp, and just recover normally. Mirror shield again is really good. Obviously we can mirror shield Falco's up-b, but sometimes you get nervous in tourney or whatever and can't do it. Just practice it a little bit, it's crucial! Arrows are good offstage against Falco, so use those and mirror shield the recovery.
