I'll talk about the zss match, because that's what I know~
1. Why are you scared to grab an armor piece that's right in front of you and be god tier amazing and **** people?
0. Why you platform cancel walk into getting hit by an armor piece
2. Why you jump from 4.5 sword lengths away and do a sh forward air
3. Why you jump from 6 sword lengths away and then aim for empty space with the falling nair
4, Why you take shield pressure from 4 sword lengths away and instantly jump fair to hit some air
5. If that roll was intentional it was pretty good, I'm not sure if he read that though but you got down smash'd
6. Why do you always aerial so early?
7. Why do you bair or nair when it's uair season?
8. Not sure about you, but in my experiences, pivot grab shenanigans aren't too strong against ZSS, but I could just be very bad at the whole thing (and I know you're pretty good with them, but they didn't really work out much for you here)
Generally it seems you go for grabs a little too much and you're using nair nearly entirely for defensive measures over aggression/pressure
WHY YOU SPAM DOLPHIN SLASH
Often you would retreat from closeish quarters while you were on the ground in neutralish circumstances, gotta remember that marth has god tier walk and zss' is like 1/1000th of the speed and other than dtilt she has nothing fast/long ranged enough to handle that close quarter pressure.
In some part sof the second match and at least a nice bit in the third you were edge guarding/gimping well/properly - the whole ledge drop lazer thing he was doing was sooooo bad that I felt like yelling DOWN TILT so loudly that it would rip through time and space and you'd suddenly have won the game in just 2 matches instead of 3. You ***** him third match with some BAIR STANCE.
Also full hop dair stuffs isn't that bad against ZSS at all (as much as you'd think her having dat uair would negate that).
Nice win though
I'll prob watch some more later
