Something I wrote up somewhere else, but feel could benefit players here:
I'd just like to throw out that I've had a few conversations with a really knowledgeable player on incorporating dominant elements of certain characters, into other characters gameplay.
I was reminded of it by reading a snippet on smashboards from DR.PP, talking about his working dashdancing into Falco's game. To grossly paraphrase, he says that a lot of players will just cut sub optimal parts of characters game, out, which is to say, Falcos wouldn't DD because Falco's DD is relatively poor.
DR.PP used DD with Falco by acknowledging that on its own, it wasn't that good, and looking for a way to augment it with another part of Falco's game. So now he incorporates DD, at very specific distances, while also keeping laser relevant. Bam. Falco meta has DD now.
What I'm trying to say with all of this, is players need to do this more. Look to other characters fortes, hell, look to other players fortes, and incorporate. Samus as a character spaces with lots of micropositioned Ftilts and Jabs, but HugS specifically does so out of shield, as well as to bait spacing based reactions.
So from watching lots of Samus matches I've started micropositioning more with Mario's Ftilt's and Jabs. From watching lots of HugS matches, I've started using WD OoS > Ftilt to zone, as a way to move out of high pressure situations and establish a toe hold with which I can push advantage in the neutral.
I'm doing all this with Mario. In this case his tools are similar enough for it to translate mostly intact, but that won't always be the case, but players have to try this stuff. See if you can fit this part of this characters game, or that part of that players game, into your character, and your thought processes, and your style. It'll let you build upon your character and your mentality and play, while watching a match between two characters you don't play, and two players you don't play like.
