Most peaches get cocky and don't camp against Ganon. Kinda like Peachkid in Verm's match.
Peach is one of my favorite matchups with Ganon if the peach approaches. They're sooooo easy to bait. Campy peaches are ******** to fight though... the only way to win that matchup is to do a bunch of stupid Ganon stuff that should never work.
Anyways, as far as Verm's match goes... I really don't see anything you can improve on, since Peachkid was making so many stupid mistakes. Each time he side B'd you, he let you take away 1/4 of his stock. And he did it like 5-6 times lol. He did some decent peach combos, but he really seemed to lack any advanced sense of how to play the game (at least in this match).
You said he did better the second match, but I'm guessing it was because it was a CP stage (plus you got some early kills first match).
Verdict: another peach senselessly slaughtered by a Ganon unhindered by veggies. They say "an apple a day keeps the doctor away"--well I say, "100 turnips a game makes Ganon really lame".
Or something like that.
