Almost every time I play a Falco as Falcon, I take off straight for the ledge (I think it comes from my Samus in that MU.) When I'm onstage, try to keep from FFing anything unless it's well spaced, like a Bair. I think Dsmash is our only "safe" smash in the MU. Ftilt is good on spacing, as well as Utilt, mainly when Falco is on the ledge, since we can take advantage of his poor aerial mobility. I normally expect a lot of spaced Bairs, Grabs, Lasers, and Phantasm. Nair seems to be situational since it can put him in a position to take an OoS option.
