Can Peach do the Marth killer trick? I would assume she could if she FF's it. If Samus can do it, Peach should be able to. There is an edgeguard right there, and especially effective one if you constantly drop below the edge to avoid turnips and aerials.
Just so you know, anytime you mention "your friends" or anonymously, "the peaches that I play" (which implies that you play them frequently, which implies you know them well, which implies friendship) when referring to a tactic or technique being unnecessary or ineffective, you come off looking like a scrub. Your friends aren't the only people who play this game. If you don't plan on going to tournaments and stuff, that's fine, but don't come here and misinform people that do go to tournaments about what a character can and can't do.
All a peach has to do is float out towards the Marth backwards and then wait and see what he does. You try to fair, she stays out of your range until you miss and bairs you, gg. You try and go below her and up b, she falls out of her float and grabs the ledge (before or after the up b, which ever is more suitable).
Marth doesn't immediately grab the edge from his up b, so all you have to do is fall from above the ledge, from behind the Marth, and grab the edge after his up b and he dies. I do it with Jiggs sometimes when I can't bair like a maniac.
Ask Overswarm. He knows ; P
