Aside from the input errors try and improve your punish game. You missed some really big opportunities to open luigi up/get a kill. Optimize your conversions, get as much as you can from your dash attacks and utilts. At low percent dont be afraid to do things such as dash shield after a dash attack, block their aerial and punish. Cant afford to miss juggles/punishes. There are times when you punished his landing well but didnt push it any further as much as you could which could of potentially tacked on alot more percent/got the kill.Also CRZ, watching your set against J. Miller (great game 1 by the way) You should probably work on your option select in a tech chase. I notice you rolling back after a missed tech and I swear Luigi's everywhere always know when you're gonna roll back. Some of your utilt punishes whiffed and you were punished for it as well, something a lot of Foxes have is always using utilt as a punish out of habit (I have that habit sometimes too)
https://www.youtube.com/watch?v=Z7J_K0e0Of8 This is a set I've recently had against Poke (has wins on Ally, M2K etc and I play him a lot because he's from my region and I can't crack his Luigi)
Rewatching this set yes yes I know I'll cut the side B's, they definitely did way more harm then good and they got baited. I also did a few panic rolls and got punished for it, I don't know why but Poke is the only player I know that triggers all my panic options, some criticism here would also be appreciated.
You got grabbed waaay too often. luigi should never really be able to just dash grab you when your essentially in neutral
if you are going to pressure shield with nair or bair make sure you are not moving forward. If you move forward it becomes not safe. I tend to only use bair to anti air because pressuring with it is unreliable.
go over dair uses and add fox trotting into your game. fox trotting mixed with dash shielding is really useful for mobility
foxtrot for speed
dash shield to give you time to assess your opponents state(Are they attacking, are they jumping,are they moving closer, away etc)
