Id like to say falcon is even or 6-4, after falcon experience in a tourny today (we have really good falcons lol). Falcon is really fast. Like seriously. Not just his running speed as some would think. His main moves are really really fast. Uair, fast, hardly any lag when not autocancelled, kills offstage. Jab, nuff said, comes after uair leads to grabs. Nair, so what if it has no priority, it doesnt need it, it doesnt go up against other attacks. Dair- autocancelled dairs are good. Falcon kick is pretty good. Falcon's playstyle is about as similar to ganny as yoshi is.
Spamming pivot grabs doesnt work, falcon can just land outside and punish with a dash attack to uair or something similarly gay. Yoshi's bair is his main winning point in this matchup, because it outranges most of his attacks while being quick and hard to punish. Cgs are good, but most of my matches were on stages like yoshis island and lylat (unfortunately), and u cant cg there, and grabs arent exactly easy to land. Yoshi can combo falcon fairly well, but falcon can do the same to yoshi(seriously, good falcons are scary). Falling uair->jab->grab is really good, so dont shield it, pivot grab or just get out of there. He can have trouble killing, but he actually can edgeguard yoshi pretty well with uairs. Yoshis dair>falcons upb. Lots of tilts in this matchup, u need the quick priority.
Dont make claims about falcon without playin good ones, we dont like it when people do it to yoshi, so dont do it to falcon.
Thats all i have to say on that matchup for now. Falcon is crap online,so dont base experiences on him on that.
