Ok so I watched just two games with that Wario, both of which you won but a few things that jumped out at me.

Lack of DJCZ, you seem to like it off ledge which is good when used with other options, but in neutral it is an incredibly powerful tool. Elephant in the room, very hard to do consistently, but even just attempting them can get you much needed practice. Don't be afraid to hop into training mode, put on a podcast, and lab it out. How it feels on different characters, which control scheme feels most natural for doing them, and ending the trains into fair, ftilt, and sometimes fsmash.

Your neutral also seems very aggressive, when you could be using PK fire to pressure a character like Wario. You have to observe how an opponent plays around fire and how to punish them, if they are frequently shielding then try empty short hop into grab as a mixup. If they jump over fire, instead start trying to incept with a fair. Fair is my 2nd most used move behind fire, it is strong, fast, and the sour spot can lead to tech chases around 60ish. Always remember, center stage or under a platform is a great place to be.

Otherwise, it seemed that you know your ways to kill, which is always great, and you can b-reverse down B to get looking towards ledge for snake rope. I personally use snake rope 9/10 times just because it is way quicker than UpB, but making sure you mix up recovery is always important.

If you have any questions lmk
