If you all haven't seen the vid already, the new "wavedash" I recommend checking it out. It's pretty cool and effective. I'm not gonna waste time explaining it cause there's already a thread. But unlike the other characters Falco has the ability to actually do his dash attack and go instantly into his up smash. Therefore that increases the range of his dash attack and makes it quicker as well. It's pretty cool. All you have to do is do an up smash as soon as the dash attack lands.
