Learn how to access your neutral jump and empty pivot, since many Falcon's just nairplane in with a full dash since it covers so much space, but it's such a common Falcon option that it's quite easily punished. Just like Marth, you have to space very well to maximize Falcon's aggression in a safe manner, especially cause he has hardly any disjointed hitboxes compared to Marth. Also, learn when it's a good idea to chase someone off stage. As Falcon it's so hard to hold back the urge to finish them off out there, but Falcon has to be super precise and surprising to get most edge guards. Also, never forget that Falcon's bair is actually a wonderful well rounded move, that can be AC'd. uair, stomp, nair and knee get all the attention but Bair from ledge is super good. On that note, Be aware that it's a lot harder to FF to ledge with a Fast Faller. You have to be quick and if you're too early or too late it could be curtains for your stock. Falcon requires practice for you to control him properly (i.e. not lose stocks to your own mistakes)
