What is there to the Peach match up?
You run, run, run.
How can they possibly catch up?
And if Rickerdy says anything to answer the above with the usage of bone-walking or free pulling, I'm ripping his head off.
At least you know what they are
and I need this head tyvm :/
Assuming you're talking about Sonic running away, you don't use either them of them for approaching, they're for Peach running away. GL finding a Peach who can actually do either of those techs without B Sticking. If the Peach does B Stick though, you're going to have a field day with punishing their free pulls and iffy spacing
Anyway, pretty much run, run, run. Peach trying to bait you out of her Float? Walk away. Peach chasing you? Run. Peach pulling up a Turnip? Run up to her and tease her - grab her or heck, just stand there and see what she does - make her know it is NOT ok to pull up Turnips in this MU when you're in a neutral position because you're Sonic. Frustrate her - this MU is more about beating the Peach player rather than beating Peach herself. If the player gets angry, they're more likely to mess up and thats when you can run in with aerials/grabs and catch her out
Despite Peach being a bit slow, she can catch up to characters but Sonic can make it really nasty for her to catch up due to his speed. You want a big stage like FD where you have lots of room to run. Turnips aren't Lasers, they don't force approaches as such, they just build up a bit of damage or create traps. So don't approach her if you don't have to - let her do the work for you. You only need to be careful of Turnips when she's chasing you and throwing them up to catch you out when you're running away from her
If Sonic was running away from me, I'd take the chance to pull up a Turnip and proceed to Glide Toss it up depending on where you were. Sonic only has so much stage to work with. Peach wants to stay in the middle and try and predict where you're going to go and punish that. This is difficult on a big stage or one that has an odd layout
Get the lead and run around her and for goodness sake keep your options open so Peach can't get a lol string on you because if Peach regains the lead its going to be a nightmare getting it back if she camps and is patient
In the eyes of a Peach, this is basically the Wario MU but your speed is on the ground rather than the air. Nair is also my 'grab' in this MU - dangerous to you only if you blindly run into it
Sonic needs to take his time and out-patient Peach. You guys can live up to around 170%, maybe even higher (I think the highest I've had was around 220%) and more due to momentum cancelling and Peach's inability to land any sort of kill move provided you play safe
Peach will want to CP you to a small stage so you're limited to where you can run to. Get rid of Brinstar and possibly SV. CP YI's or Lylat - her Ground Floating is crippled there so everytime she goes for a Ground Floating Nair to punish your incoming spindashes, she'll do a Jab instead. You've also got invincible spindash and a tilting platform to work with
More to come, probably
