If a move is coming out that can beat Cloud's U-Air (mainly sword dairs) I prefer using U-Smash to cover it, the range is cray.
Also, why has nobody brought up Cloud's dash dance? It's amazing.
Cloud's dash dance has the same exact inputs as regular dash dancing... you just dash back and forth. Due to the fact that you're using foxtrots, it also allows you to control speed and distance. Along with that, due to Cloud's mobility (especially with Limit Break), his dash dance beats out FE Dance Trot. The only other character who can dash dance like this is G&W, but his timing is a bit slower, ruining it's efficiency. Along with that, Cloud has IASA frames on his init dash which allows him to cancel it into grounded moves (ie: jab, dtilt, utilt)
He has a ton of options out of this to keep himself unpredictable and terrifying. If he's dashing away, pivot F-Tilt covers opponents chasing you and beats hitboxes from dash attacks/rushing moves due to it's range. He slides crazy distance when using it, too, so you're naturally spaced out in case you hit a shield to avoid direct OoS punishes. Cloud's pivot grab will beat shields and can grab opponents going after him, along with taking certain characters out of moves (ie: spindash). Similar to his pivot F-Tilt, this slides relatively far, too. If he uses pivot F-Smash, it has tremendous reach, kill power and damage, which makes approaching him during this even riskier. Along with that, using reg Cross Slash will catch SH approaches and does 19%, along with giving you shield mix-ups if you hit one. Blade Beam can be used to keep up pressure and generally keep your space from the opponent. The LB versions of both of these moves are equally, if not more effective.
When dashing in, Cloud has quite a few options to punish opponents. He can use a boosted dash grab, which is generally a good option in case he doesn't have his Limit Break, as it allows him to create space and charge it. Cloud's dash attack seems to have really good priority, beating out a lot of moves and trading with others. Along with that, it has a bit of burst momentum and decent damage, making it a good option to replace dash grab when looking for damage specifically. If spaced properly, he can use Jab/U-Tilt to punish the opponent, Jab allowing him to tech chase, U-Tilt allowing him to go into gdlike juggles. If spaced decently, he can cover the dash in with D-Tilt, popping the opponent in the air for more juggles. He can also use Cross Slash/LB Cross Slash for really good damage. If punishing a laggy option, such as Smash Attacks, he can dash in with Finishing Touch to end it.
As he's foxtrotting during all of this, he will always have shield available and his SH/FH aerials. Coming back in with SH N-Air and SH U-Air are both really solid options, too. If Cloud is dashing back in, to avoid running into lasting hitboxes or avoiding another move, he can stall his dash in by using the turn-around dance trot, which dashes in place. He can then go straight into a regular dash or another foxtrot, allowing him to keep his momentum.
Dash dancing improves Cloud's neutral and advantage (tech chasing) a lot. pls use it more.
edit: also cloud's u-air is called "raise the roof", coined by
