Don't say Lucas has faults, because he doesn't. Coming from an experienced player all I can tell you is this:
Gimp! forgetER GIMP!
If you can play smarter you WILL win, no exceptions (Unless its tornado spamming metaknight then its G)
Learn how to wavedash and wavedance, also learn Lucas's Nairs Dairs Fairs and special smashes.
If your up against lvl 9s that won't do you good, they're computers not players so don't get used to them.
Learn how to DACKUS, lucas can Up-smash and slide across the floor with momentum from either a w-dash or short hop.
That's the kind of stuff that gets you into apex. Also if anyone's going ice climbers call it quits because if he wobbles your dead.
