id say try more ken combos on peach cause its easy to do on peach.....
abuse f smash more with dash cancel
up throw to f smash at 70% or so on spaceys is nice tipper lol
get out of foxs up throw to up air by pressing B side more to gibble him with it
counter fox and falco when he's be uping to the stage and go for a fair kill
JC the grabs
up air from ledge onto stage is cool
there wasnt to many down throws on peach or anything to mix it up just forward throws
needs more gay gimps on spaceys aka off edge combat
watch m2k, diakonos, falcomist, azen, zhu, full metal marth videos
and when people are at to high % to kill get them off edge and kill with shield breaker
cause marth has trouble killing after to high percents
id be glad to have a sibling thats pretty decent like yours =D peach and marth team yay.......
