I feel like Corrin shouldn't be using sideb against a grounded Cloud for the most part; it's extremely punishable. Uair is good, I'm not sure if you can punish a properly spaced one on shield, and it kills. You'll probably just have to accept that this is a good move and move on lol. Fsmash you can SH or dtilt over/under if it's not angled and hopefully you won't be in it's optimal range often, try to keep them on your Buster/Fusion Sword and they shouldn't be busting out fsmash that often. Cloud's not really that vulnerable to counters, but they're still annoying... grab more i guess?

Surprised nobody is having problems with her bair...
Bayo? idk, Cloud's recovery isn't nearly as vulnerable to Witch Time and dsmash as say, Ike's. It's more of a Mac type stituation where our recovery is so short that we either snap or we end up just below the edge and grab after the animation. Should you have to use it above the edge, just do the downward strike and sweetspot from there. I think Bayo is good for Cloud; we can take advantage of rage very well and we're fast enough to punish misused Bullet Arts. She's also really vulnerable to offstage nair with her slow airspeed, and if we steal her jump with a nair she's 100% ded. She can drag us offstage with fair tho,held nair can kinda ruin us offstage, and we're tall so we get hit with Bullet Climax easier. Witch Time is also less of a problem for us because our multihits and lingering hitboxes will probably catch her if she goes for anything but a smash. Not to say WT isn't a problem; that move is good.
Also, I've never played FFVII, but AC Cloud was SUCH a badass.

His AC costume does look bad on 3DS, so I use both costumes on 3DS tho
