So via battling a Peach main today I learned the basic MU and by reading the Peach guide by Dark.Peach.
I am changing my side to 35-65. Peach is an effin *****
Turnips are a freacking nuisance it's a huge part of Peach's Metagame. Turnips mess with our camping game, can pressure, limit options, and can gimp Lucas really well. Those turnips rack up alot of damage over time as well to go along with Peach's floating. I don't even wanna go into Floating....Nair, Fair, and Dair + Glidetossing.....just a massacre. Although PK Fire stops turnips it is not better than Turnips.
Turnips aren't that bad <.<
They don't mess with our camping game. When she pulls out a turnip, predict her throw and PKF it, PKF plows through turnips. Turnips don't even do that much damage. If you're getting gimped by turnips then you're doing it wrong.
Floating:
Fair: 16 frames of startup, shouldn't be hard to avoid. Don't shield it...............
Nair: Nair is mostly punishing. I doubt a Peach would use a floating Nair, she has better options.
Dair: The dumb one. Unpunishable when landed. Learn to predict Dairs. Most peachs don't directly float towards you, but rather use a Dair after a SH float when they're near you.
Glidetoss: PKF wrecks glidetosses.
PK Fire is a great move to use against Peach however.
Peach can get a grab off of Dair when Lucas is shielding. This leads to Peach's CG which 1.) refreshens her moves and 2.) gets us off the stage and 3.) does annoying damage. DODGE! Freacking get out of there. If you get caught basically your screwed alot more than you were a few seconds ago.
Lucas might be able to air release out of her grab, not sure though. It refreshens her moves.......yet they still kill late as **** (except for Usmash)
With Lucas we can't get out of the CG.....which sucks alot.
Back to the PK Freeze gimping.....uh yea no.....use PKT. PKT is the best gimping tool we have. You can try and follow Peach for a kill gimp buuuuut it's risky and could end up in getting gimped ourselves so PKT for the safest and most effective gimp. PK Freeze is really hard to Gimp Peach with though on some characters I could see it being more effective.
I already said this. Peach's Dair goes through PKT and Fair probably does too.
IMO the best moves to use are:
PK Fire, Fair, Dair, Uair, Bair(anything that is in air works)
Though for killing: Fair, Uair (like Levitas said)
Here is what the Peach main had to say:
We battled for basically a couple hours so we both learned alot ^-^
And that's basically what I got from the basics. Hope it helps *goes back to the OTL*
