Really quick I know everyone likes to watch armada videos (which are super helpful btw) but I would also like to point out this set.
https://www.youtube.com/watch?v=EEnBZ-kUEhc I think it can help a lot to watch this. It's a good example of a less ideal way to play a MU and still be very successful.
I'll do your ganon set since everyone seems to be ignoring it and I come from Florida which is densely populated with ganon mains.
Before I start don't listen to the commentators. They say some things that are either
A.) flat out wrong or
B.) obvious info you should already know.
They weren't bad but don't listen to them for ways to improve your game.
Rolls
First of you roll in too much vs ganon for example at 3:43 you roll into ganon and go past him if the ganon were faster he easily could have gotten a grab and from there he can do down throw into a guaranteed follow up. I feel like there were a lot of OoS options that you should have used before the roll in. I would say Nair OoS or Up air OoS could easily cover a lot of ganons options in this specific situation. Also if you wanna know why roll in is so bad just look at 4:19 when he kills you because he covered the option.
Okay so besides rolling in you just roll too much at around 7:37 you roll away towards ledge for spacing reasons but a float out of shield is better in every way in this situation. Just float high enough that his DownB can't touch you and you are good.
Approaching Ganon
This part is actually pretty simple and your approach wasn't even bad. You dash attacked far too much though ganon can punish with full hop Dair and that can be brutal because he has some follow ups. Honestly against ganon I would run up FC Nair or grab instead of dash attack both options work much better.
Spacing
Your spacing was good and bad it varied a lot throughout the set. Vs ganon you need to stay out of his hitboxes like you would against Marth. Something that makes Peach vs ganon challenging is her lack of good trading options (something she has against a lot of other characters.) Basically Ganon can constantly throw out hitboxes and you have to space around it. Turnips are a good way to deal with this. I recommend throwing turnips while airborne against ganon (unlike vs Marth) because grounded turnips actually don't limit too many of his options considering he's probably fishing for aerials. If you space outside of his Bair and Fair it is easy to use turnips to cover his landing options and then approach and continue assaulting him. Honestly if Tribulation was more aggresive with Dair he could've gotten a lot more approaches on you because of how you didn't cover this option. Basically with spacing it plays similar to the marth MU just wait outside his hitboxes or get inside of him if you are in the ganon zone then it's going to be a very unpleasant ride.
Edgeguarding Ganon
This is easier than you might think. Ganon does have Mix ups that do make it a lil challenging, but I think Peach can edgeguard him without trying too hard. I mainly believe this because of Turnips ability to cover a lot of his options, his inability to sweetspot the ledge, and the huge amount of landing lag that goes with him landing on stage. Throwing out a turnip blocks his downB low recovery and FC Dair to Nair covers his lack of sweet spot, so does bair but this can be teched along with how Bair can be Di'd out of so keep that in mind.
Also,when ganon gets on stage there are better options than just forward or back throw especially when he is at low or mid percents. FC Nair or Fair can work really well. If he lands in front of you with your back to edge than go for a dsmash 9 times out of 10 players won't cancel the hit so they get sent towards center stage and the knockback is generally higher than Back throw.
Panic Downsmash
Okay so this is a huge problem for a lot of Peach mains it seems. Once your opponent starts pressuring your room and you begin to feel the game slipping a lot of us will start throwing out down smash to try and comeback and regain momentum this usually does the exact opposite of what it's intended purpose is and I saw you panic Dsmash in a couple of the games when the Ganon took control of momentum. Basically this comes down to keeping a cool head and remembering that it's not 2004 and that Peach's Dsmash can't carry you to victory anymore.
Honestly good stuff and congrats on second place. Sorry if this info isn't helpful I like to think I understand the MU but who knows FL Ganons could just be playing it wrong lol.
