You should try a character who has an advantage over Olimar... like Ness. Ness can break through any camp actually and he also has a pretty good camp game of his own.a) Sitting from the side throwing Pikmin, camping forever until you'd approach him
or
b) C-sticking
P.S. If Colin's up B-spamming Ness is rank 9, then I should be rank 8. I've gotten a lot better since ADAT. >_>
Using A + direction to do a smash attack starts a dash and gives you a chance to trip. Unless you've changed your controls, you should be "C-sticking"... it's not merely a preference, it's strictly better (unless you want to start a dash with your smash attack, such as if you are playing Luigi or you are on ice). What have you got against the C stick?
Also, pk thunder rules.
