Falco does well in the floaty match-ups, but you need to go into them with a different mindset than non-floaty match-ups. Normally, Falco is looking for that one opening that is going to lead to a massive combo, but against floaties you are mostly only going to get 2 or 3 piece combos. Falco can pretty much control the neutral if you can effectively use all of the different laser heights (low, high, full hop, instant double jump, etc.) as well as mix up your timing well enough. Falco doesn-t edgeguard floaties as well as he does other characters because of their ability to drift around offstage as well as the risk Falco puts himself at offstage, so be more creative with your kill options. Try to catch a bad roll/dash dance with dtilt. You can also use jab -> bair to get kills fairly reliably.
