His down A is his spike...
...i was good with Lucas in a Wi-Fi match, but it was pretty laggy, so i just spammed PK Fire constantly.
I can't seem to use Lucas well, he isn't very quick, and can be knocked back pretty easily, although i find his PK Freeze more effective than Ness' PK Move (don't remember what its called, its his B move), since it will still freeze the opponent even if you don't charge it up enough, whilst Ness' move will do a pittance of damage if not charged up properly.
Although i find Ness' Smash Ball move to be better than Lucas', but then again, competitive players usually ignore using Items, so that fact is quite...unimportant.
