I know! I think I might've worded this not so well. Maybe I exagerated a little bit, but I said it more on the mood of the lastest patch (1.1.1) in which people thought Kirby was hit very hard by the Shield Stun changes. I mean, he got more mobility now. Still slow in the air, but now he can be more of a threat!
In my opinion being patient against Cloud is a must. Mainly against his Limit Breaks, in which a Shield must be ready. I think I was hit by Finishing Touch like three times on those two days mostly against Clouds... many of them aren't that good (with him), but I was pretty close to the hitbox. Its lag is no comparison to the KO Punch (if it misses), but it is way safer to avoid, at least in my opinion.
Still on the Cloud matchup but speaking of his projectile, it is pretty good against Shields. I found that Down-tilt "clashes" with Blade Beam. So, if you don't want to have part of your Shield lost, here is a way to keep it
It's laggy as heck so Cloud shouldn't be able to punish you. But it demands timing!
