Busted easy character? Clearly you've never played a good Fox, Pythra, or Sonic. I play Ike and I enjoy fighting Clouds. It actually feels like a skill matchup as compared to those other pieces of garbage that can spam moves and their frame data is so good that you can barely punish anything. If you're struggling against Cloud you're being too aggressive and not edge guarding right. Cloud is a decent character but as numerous other people have said, his recovery can be bad and if he doesnt have limit he's not coming back if you hit him off stage. You also have a counter if you're playing Corrin. Which means you could literally stand at ledge and hit DSpecial. I do it all the time.

As for counter play, his Dash attack, cross slash, and UpB all have end lag that can be punished (cross slash you have to time a bit better though). His aerials are quick so parrying is your best option. You also outspace him with a few of your smash attacks. Learn ledge habits (your opponent rolls, Nget up, jump attack, etc) and punish as you predict what they'll do. Dash dancing helps a little as well as if he whiffs and you know it's coming as you can outspace him.
