Nuh-Uhhh!
So, I'm apparently fancy?
Well...sort of yes but that isn't always a good thing
You have good 'mix ups' but the problem is that you use them all the time. Stuff like quickly dropping your float, running back and forth, only doing Jab 1, randomly crouching, running up to your opponent and using Toad/grab, dropping down from your float to F Smash, airdodging past instead of attacking...it's good you can think up those things but they should be used sparingly, not as your core gameplay. Ironically, you hardly ever use your Float as a baiting tech because your Peach seems to be wearing brick shoes throughout your games
Sometimes, I feel that you're more hellbent on pulling out something 'technical' and 'confusing' rather than reading your opponent to get damage on them - a lot of the time, you do things twice if you don't get it to work the first time. I'm talking about the really, really unsafe stuff like running up to Ike and using Toad or dropping near him with Peach's poor airspeed and flimsy airdodge and trying grab him. You're constantly trying to pull off high risk things with a character that doesn't get much reward out of doing those things. Peach doesn't have the power or weight to make doing this worthwhile, nor does she have the speed to suddenly approach/escape as a mix up to throw the opponent off guard
Because you're so focused on doing your own thing, I don't feel scared watching your Peach. You don't force any pressure upon your opponent - you should be pressuring your opponent AND THEN installing some fancy stuff in afterwards because it's more likely to work against a pressured opponent
You need to do more 'standard' and 'basic' Peach stuff, like camping with Turnips and using them to cover your approaches (you run away a lot and like to be evasive but you need a Turnip to help cover yourself) and spacing aerials with a combination of Floating and jumping. Watch any other Peach and you'll notice that they all do this and they do it for a reason - because it works
I can't tell if it's because you're trying to mindgame your opponent or if it is just the case but your reaction time could do with a bit of work imo. Watching you, it looks like you're very slow to react to stuff and you get hit by stuff you could have avoided and miss out on punishment opportunities. This really doesn't help you if you're determined to have a confusing playstyle because you won't capitalize on the openings you make
Your defense needs some serious work - you hardly ever throw out any moves to protect yourself when you're running around. Part of what makes Peach great is that she has near lagless aerials and with good spacing they're difficult to punish. Abuse this more
Watch your game 2 vs Ike. Ignore the loss and watch the first part of the match. You dance around a lot and end up losing your first stock in just under a minute. The change in your playstyle is pretty dramatic - you start putting the pressure on Ike with the help of Turnips, well spaced Fairs and decent use of Jab/Dair and for the grand finale, you read Ike's airdodge and Bair him for the kill
I just feel that if you played more like that instead, you'd have a better Peach. You've got the mix ups down but I feel you're making a poor decision to not make your playstyle up with more of the basic stuff that makes up Peach's core gameplay
Like I said in my last post, I advocate people to not always (key word) do obvious/standard Peach stuff and incorporate mix ups into their playstyle but standard for a reason - it is tried and tested and works
As far as general MU stuff goes, camp with Turnips more and Toad Ike when he Aethers, you missed out on a lot of chances to do this and instead got caught up in Aether and got forced onto the ledge/offstage/in a bad position
That's my take on things anyway. I don't think your Peach is bad because you can do some good stuff and occasionally you do - you just choose not to in favour of
I look forward to seeing more vids of your Peach
