Thanks. Just L-Cancel everything, it's not about technique it's just something you gotta do. I try to play safe with marth, poking and just playing the spacing game but I'm pretty bad to be honest. I can't DI for my life and just mess up my inputs and decisions most of the time.
Still would be fun to see you share gameplay even if you don't consider yourself good. watching gameplay of yourself is the best way to realize what you're doing wrong and improve on it.
