Should I play super aggressively?
You're bloody
falco, only one character in this game can play as aggressively as you can.
My friend plays pit and is a much better player than I am. Here's the key: your tilts own. That ftilt comes out amazingly fast and has good range, and the utilt punishes sidedodging pretty well. Since my friend's pit spams sidedodge I'll let you know what to do against that.
If he tries to roll behind you into a downsmash, sidesmash in the direction he rolled to. I swear by all that is holy that the greatest mindgame Falco has is his sidesmash. It has an odd hitbox, takes a little longer than most people expect to come out, and has slightly more range than people seem to realize (at least, non falco mains). Plus at medium high percentages, when down throwing them is just out of range of a DLX, you can still dash up and stutter-step a fsmash. It requires a lot of careful timing (especially since I'm terrible at stutter stepping, so I mostly just stop dashing and fsmash) but once you get it down it keeps your godly down throw scary relevant for the whole game. then you just have a prediction game... will your opponent airdodge out of the downthrow to prevent a dlx, or will they keep flying and airdodge the fsmash?
Don't bother reflecting the arrows for the most part. Good pits (hell, even bad pits like myself) will not get hit by the reflection (they know to angle the arrow down just as it hits so a reflector sends it into the air), so you're just as well off dodging it. Better, actually, because the lag on spot dodges and rolls is lower than shining. Other ways to avoid lasers: go airborne and forward. Airdodging is great for avoiding arrows, and while Pit has a monster arial game, you do as well. Also shine still works as an offensive option in the air.
Illusion is a strong offensive option against all characters because it's pretty unexpected, and unless you see it coming it's hard to defend against. Even when you see it coming (recovery) there's still all kinds of tricks available to illusioning falcos, such as cancelling it or even specifically aiming it short or long, high or low.
Remember: you cannot DI through the angel ring. As soon as you hear "HI!" you should be DIing away from pit in the opposite direction pit just moved. I'm sure you knew that, but as Pit isn't exactly a common player it's not unheard of for even fairly experienced players to forget this little important rule.
Like I said before, my friend spams spotdodging into grabs. Fortunately Falco is a pro at punishing spot dodging. Your jab combo, your uptilt, your sffled dairs, your shnair, your shbair (sex kick ftw!)... even your fsmash gets the job done. The reason I am able to beat my friend's pit on occasion is because I know how to punish him. Hard. Falco has all the tools for punishing a Pit... a monster arial game (full hop off the ledge to illusion spike back on is such a thing of beauty when it's pulled off) and fast tilts/smashes (that dsmash of yours is fast, by the way). Plus a chaingrab.
don't try to punish Pit's SH retreating Nairs, they autocancel and you get screwed.
Sure you can punish SH retreating Nairs. Laser him. It's not much of a punish, but it means that his retreating move gives him 3% damage.
Quick question, does the front hitbox of our usmash go through the Nair of pit? Because a hyphen smash might do it.
