Your not a good Fox if you don't know how to wavedash, or waveshine, or shffl, period. I hate to sound like a d!ck but don't be mistaken, don't think that because you beat a guy who wavedashed meant you were great or anything. Go to a tournement, or play me (I'm not even that good) but if you don't know how to DSHL or waveshine, or L-Cancel (yet alone apply them into your game) my Ice Climbers will just own your fox. Tell me, because I'm very curious, how you play your Fox. Is it defensive, offesnive, what moves do you use frequently. Because I'm guessing if you don't use any ATs, you do a lot of ground laser spamming, and forward and up smashes.
And lol at playing Peach without Float Canceling.
