olimar is one of our worst MU, he have a lots of things than can punish us, the only real problem of olimar is his recovery, is bad, he depends of a ledge, so when he try to recover you must grab the ledge first, isint very hard, only need the right timing.Gimp him is our only chance to get a good adventage inthe match.
our spaming can stop his spam (at least would be more dificult for him hit us with a pikmin), and how a last card we have our Zair( the Zair of Link is better than Samus Zair when we need hit small characters)
i dont know if he have good or bad DI, but, whether good or bad, his light weight can be a desventage for him.
about stages, well, i thing about norfair how a stage than will give more adventages to olimar, the "V" form of the stage give to Olimar a perfect angle to throws his pikmins, and the 3 ledges in each sides, can help his recovery.
if is legal in your region, pick PT, the platform than carry us around DONT HAVE LEDGES , and if he cant land at the platforms, the impact with the road will kill all his pikmin, and give him a big amoun of damage. Also, the F-ZERO machines have a great kill power, some machines have more kill power than others, but anyone to hit olimar will kill him.
also Jungles japes is good agains he. If he touch the water, he can say good bye to all his pikmin (to exeption to his blue pikmin) with out pikmin we would gimp him easier.
