I've been thinking of Clouds issues as a character because I've noticed mid level players struggle in the matchup and honestly play it really wrong. Here is my views on Clouds flaws and how to beat them, or just general Cloud counter play! So here is what I have come up with.
-Cloud has predictable jump ins, almost any character can atleast anti-air him consistently. Lucina and Marth for example can Ftilt, or most characters can swoop in under hitboxes like Jigglypuff and attack places where the hitbox "arcs" if they are spacing/approaching with Nair. It is similar to Marth counterplay in Melee
-Dair can be beaten simply by standing under platforms, or some characters can use Utilt like Lucina and Marth to attack the side of Cloud. Or some characters can just bait it out when Cloud is landing then full hop Bair him during the end lag or during the move (the move only covers the bottom of him) I'm pretty sure this is a universal option, and can be replaced by RAR Bair or Nair. Just do not go underneath him
-When Cloud is trying to land Limit cross slash there is a few things you should not be doing against him a lot. Things like jumping in on Cloud is a bad idea because Limit cross slash is the best anti-air in the game and is also relatively safe ish. You also should not do things like go to places where you will eventually be forced to land like the smashville platform or onto Battlefield platforms or whatever because LCS is a guaranteed hit when you are landing.
Also generally shielding ALOT and baiting out limit cross slash with empty hops into shield is a good idea, but don't shield to predictably because if you get grabbed and thrown offstage then LCS is really easy to hit depending on the character (Like Corrin, Falco/Fox, Ness, etc.)
-Speaking of landing. NEVER try to land into center stage. There is a few jukes you can do on Battlefield where you act like you are going to land on the side platforms and when he goes to Uair trap you onto the platform you double jump to center stage then take the advantage that is sort of a one trick pony. The place you really want to go is to the ledge. A lot of characters just can not handle his juggles so they need to go the ledge, Clouds ledge coverage isn't as good as other top tiers in my opinion unless you get hit by a meaty limit cross slash on neutral get up or get something read. But in general it's better then trying to land. I think most times Cloud is trying to land should end in an edgeguard situation.
-Another big problem I see that people do when trying to escape platform pressure against Cloud is that they always try to do then fast fall off of a platform, or shield an attack or jump out of shield. This is the most common habits I've seen, and mixing it up between Jump air dodge, attacking, rolling, attacking, shield and shield dropping will get you off the platforms generally unscathed unless the Cloud guesses right which option you decide to chose.
-As a general rule against Cloud and all sword characters (unless you have one yourself) jumping in on Cloud will very rarely work, his disjoint is to big to jump in on if Cloud is positioning himself just outside your jump arc. I see mid level Marios, Shieks, Ryus, Luigis etc. just jumping in on Cloud trying to get offensive pressure started and they just keep getting blown up for it and complain Cloud is bull****. Also Limit cross slash beats jump ins wanna put emphasis on that.
-If your character has a hard time getting passed Cloud walling abilities options like Dash forward roll behind, dash forward perfect pivot shield (this will force a misspaced aerial on block which you can punish) or even dash forward spot dodge can sometimes beat out Clouds walling options, but a smart Cloud player will have a lot of empty hopping so it may not always work. But it might work against a Tweek styled Cloud.
-One of Clouds under spoken biggest flaws is how garbage his ground game is, his fastest move is Jab which is frame 4. Utilt is an anti-air and does not hit grounded opponents to well that are in his face, Ftilt is actually an okay but -11 on block is pretty punishable offline with characters like Falcon or Sheik on block. And Dtilt is just bad. I think people need to condition Cloud to think jumping is bad so you can beat him on the ground consistently. I don't think every character can stop him, but Marcina, Cloud, Sheik, pretty much any top tier can discourage Cloud from jumping then dominate the ground game and combo him into an edgeguard situation. One of Clouds "better" tools on the ground is actually cross slash due to having pretty big reward and having the ability to mix it up on block if you are going to do Cross slash 1, 2, or 3
-Since I mentioned edgeguarding I just want to say so many players are **** at edgeguarding Cloud. I'd recommend watching these two vods
https://www.youtube.com/watch?v=22WnDCRluCg (This one is more useful in my opinion, it starts at around 17 minutes in) and
https://www.youtube.com/watch?v=I6ftGwBPBs4 (I think this is very difficult and I've never seen anyone actually pull it off, but hey it's a thing. <3 u Esam) I made a document awhile ago of all of Clouds recovery mixups I have seen top cloud players use. It is about 3 months old but I think most clouds recover poorly so it will be useful most likely.

-Something that not nearly enough Clouds do is dash dance SMARTLY. But when a Cloud does do it right most people actually have no clue how to handle it, a very common situation is when someone is cornered and shield while a Cloud dash dances outside your longest aerial range OoS. And most people jump in the situation and try to attack Cloud! I think people should always mix up there OoS options no matter what against Cloud. If Cloud is dash dancing when you are in the center of the stage just walking forward will steal space from him and make him lose some option utility and put him in an upclose position. (I can elaborate on Cloud dash dance uses and counterplay to it if anyone wants)
-I think the biggest thing that bothers players is the campy styled Cloud play, the one that stays on the platforms all day and stuff. And tbh my neutral is like that until limit comes into play and people handle the situation so bad. I'll give some examples
-When Cloud is on the Smashville platform people try to attack the front of Cloud often! Dtilt>Uair becomes true here (I'm 99% sure it is) and peopel jump right into Dtilt range, he covers the front of him extremely well with Dtilt and Blade beam. You can attack below him but he can Nair. But that means he is giving up his front coverage. You got to mix up how and where you attack him from. You can do things like Bait out Dtilt by jumping at him, fast falling under it then double jumping back up with a punish. Characters like Diddy and Falcon have options to beat shield while being airborne so use it to threaten Cloud. And on Battlefield people try to do the same thing then get hit by falling Uair because it beats a lot of aerials with a good prediction.
-As a small last thing here is a thing that SilentDoom wrote on counterplay towards Limit Cross slash.

Sorry for the wall of text, I've just been working on Cloud counterplay abit so I wanted to show it off! If you have anything you think I should add just tell me and I will. Or if you need help with a certain part of the mu ill help.
