LOL finally someone posted my guide on one of these threads
But yeah, check th stickies son, there'll be tons of great info on stuff like that.
And imo, i would say play stages like these agianst those people
Marth: FD if CGing isn't a problem, DL, i like Yoshi's for low kill zones but watch out for tippers, and Pokemon Stadium reduces a lot of his gay ****.
Sheik: kill your self 4 times when the match starts
Falco: FD lol, waveshine combos crazy for both sides. Spam SHL of course. Pokemon Staidum and DL are good as well. the others work too but i'd choose one of those 3
Fox: same as falco IMO
(JK about sheik, i hate the match-up but i'd say its safe to go Pokemon or FD. yoshis is good too for the platforms. of course battlefield and FoD work, but BF has gay edges and FoD ***** your SHL if you're not careful.)
