Just checked the last 2 pages and while I only skimmed, I didn't see my question so here it is: any tips/help/advice for the Cloud mu? There's a post on this very page that mentions that it's Peach's worst mu which doesn't bode well but anything will help.
There's a thread specifically for Cloud, but I'll paste what I said. And I thought the same thing, but Cloud is relatively simple if you wall him out.
Knowing what moves to use for punishing on the ground is vital. I would use down-smash, dash grab, and side B as punishers for most of his moves on the ground. Down smash is great if he tries to spot dodge (most Clouds I've faced try to spot dodge after a down-smash or try doing another down-smash if they think they are safe). In addition, some of Cloud's moves make him go behind his opponent, so downsmash hits both sides. Side B is great if he tries to roll away or block. Dash grabs are good for its range and if Cloud shields- but most Cloud players I've encountered don't block and play aggressive upclose. Just be careful on punishing his up-smash and down-smash, they are much harder to punish than forward smash.
The biggest don'ts for peach against cloud is:
DON'T fight your way down. You WILL get punished, outranged, and out-sped by his aerials.
DON'T use airdodges recklessly as a crutch to avoid him. You WILL get punished, out-ranged, and out-sped by his aerials.
DON'T rely on shorthop D-airs to approach often, he WILL grab you out of them. Use floating D-air instead.
DON'T recovery high/on stage against him (general rule for Peach, as you all know).
DON'T rely on your forwardsmash to punish him, it is too slow. However, you should try to keep either the frying pan (for its killing power) or tennis racket (for its horizontal knockback which makes Cloud's already ****ty recovery ****tier). The tennis racket is not much help despite its range because it puts cloud at a 30 degree angle to recover easily and is the least likely to kill Cloud or be used as a viable punish anyways. The tennis racket is more viable as a 2-frame ledge grab punish because it's hitbox extends beyond the ledge, but it still is hard to connect.
To get through his projectile and close the distance, I either turnip farm or shorthop D-air into his projectile (Not into Cloud) as I get closer. The D-air negates his projectile and keeps you on the offense and defense while keeping you relatively safe. Slowly walking towards him and perfect shielding works as well.
As for edgeguarding, I throw a turnip offstage to bait an airdodge or jump from Cloud, in the meantime, I am hanging off the ledge. The moment cloud starts to use his upB, drop down and neutral B him. It is more successful this way because it is safer and most Clouds upB right below the ledge than at an angle-unless he has his limit breaker. If you are sure of Cloud's position to recover, you can run off the ledge and Bair Cloud as he upBs to get a clean gimp from the ledge. The timing is much stricter, but is safer and more rewarding.
If you can take away Cloud's jump, then he basically is set-up to fail because his horizontal recovery is extremely poor and his vertical recovery is decent at most. While playing Cloud on-stage, try to imagine using a mix of tips for fighting a Little Mac and Link: you want to get close to him, but not too close because their moves are faster and have more range. Sometimes being a close enough distance makes a Cloud panic and use unsafe moves-this is where you want him to be. You want him close enough to punish him, but not too close where he can become faster than you.
When Cloud has his limit breaker, treat him the same way you would with Little Mac and his KO punch. It's best to stay near the ledge at this point (but not give up stage control). There's no need to recklessly approach him or do too many attacks-less is more in this case. Stay near the edge to get a grab or a move that puts him off-stage, so he has to use his Limit breaker to recover. Sometimes you're best defensive option is shielding because Cloud's grab game is bad (he can do Down-throw to Up-air, but Peach can double jump to evade it at high percents If I recall) and he doesn't break shields easily aside from his Forward-smash.
