From what I saw, you mainly are the agressor in your team match, ya know, running at both enemies full speed ahead, then breaking them apart, so said teammate; snake, rob, whoever it may be, can pick them apart with camp from a distance while said teammate holds stock at the same time, which you in turn you take after you've been knocked out if its there, well marth is a character that you wouldn't be the agressor with, he has to camp the wings of the stage otherwise, you'll be f-smashing til 170% unless you get a tipper for the kill, so basically what I'm saying is, marth would be better teamed with a metaknight or Lucario, something of that nature, that way you play smart i.e. Perfect spacing, propper def, superior gimping and more team grab combo's such as CG or grab release to fully charged f-smash or N-B. Kinda get what I'm sayin?
