Smash Lord
if you have no one to practice with, play against computers and just try to literally play as fast as possible while powershielding as much as you can as well as not relying on rolling or spot dodging too much (will help you not become predictable or accidently start abusing the cpu AI), also practice gimping cpu's at high speed (like when they close to the ledge don't hit them when you know they won't avoid it at the edge of the screen). Also learn dash dance to dacus (hardest technique i ever mastered to fluency) =]
