I am a Mario main lol...I've been playing Mario since Melee days.
*feels silly and goes to rewatch vids for a proper critique.*
EDIT: Alright, after watching them twice in a row, I'm prepared now.
You have a good defensive game with Mario, and I generally play the same way when my opponents are way too aggressive for their own good, which is generally what I saw in each video.
That being said, you should incorporate your jabs and F-tilt more for punishing, they're good to follow up on for some minor offensive game when playing defensive. Also, it stops you from spamming D-smash for a punisher to keep it fresh. I noticed you used D-smash way too much.
You never used Up-Smash when Shiek was at high percentage. Up-Smash potientially kills at 120%, especially when there is a low ceiling. Try to add it onto your kill list. It works wonders for me when D-smash and F-smash isn't working well.
Lastly, I noticed you -never- used FLUDD throughout all three videos, even though you didn't need it. On such an aggressive player, Approach-killing would've opened up some options for you.
Well, that's all I got.
