GGs, Metalbro, if I can offer you some advice on your characters, for Marth in general it's not a good idea to over-commit with dancing blade, the first hit is mainly mean to set up fr combos, with Falcon you seemed like you were trying to play him like Ganon because Falcon generally doesn't want to use Raptor Boost or Falcon Kick offensively, for Luigi you didn't seem to be wavedashing much and he's a character I wouldn't recommend unless you're very proficient at wavedashing because that is his best tool for mobilization, and for Mario down-b is best saved for recovery because unlike Luigi's Mario's doesn't have much utility as an offensive tool.
Edit: Thanks maybe I should play Pit more often, I didn't think I was very good with him, but I seem to be getting a lot of compliments on him recently. Oh and speaking of Peach's chaingrab, Marth, Mario and Luigi all have chaingrabs as well Marth can chain fthrow on most characters at low percents and uthrow against fastfallers, likewise the Mario Bros can chain dthrow on most characters and uthrow on fast-faller, oh and while fsmash is a good kill option for Mario, dthrow/uthrow the fair is better.
