Ok I'm going to try and respond to these points, they're all very good points though so thank you for the responses
Umm the first one was when I said you could just reflect lasers to stop laser camping I was trying to make a joke

I guess I'm not very funny but don't worry that wasn't serious
Personally I think Meta Knight has some of the easiest tech chases in the game, and as people are getting progressively better at it in Melee with Sheik I see no reason why it shouldn't be the same with PM
Fox can definitely Bair edgeguard but removing shine spike helps prevent really low percentage kills and makes the matchup more even, similarly with Fox needing more combos to kill wolf, if fox needs to combo longer to get the kill it gives the Wolf player more chances to start combos of their own and get a kill. I will admit this is operating under the assumption that Wolf's neutral is at least comparable to Fox's not necessarily better but not so much worse as to be shut down
Also getting a grab with Meta Knight might not be easy, but it's certainly doable with Meta Knights good dash dance game and speed
I think all of Ningildo's points are valid, and Fox has counter play to these tactics but I don't think his counter play invalidates the strengths of Wolf/Meta Knight.
Umm PM Marth Stages
GHZ is flat enough that chain grabs are possible there, as well as having close side BZ's for possibly easier kills while having a high ceiling for slightly harder fox kills
PS2 is good for Marth, in Melee Pokemon Stadium is considered good for Marth a lot of the time(see PPMD/PPU) because the neutral stage gives him a good amount of room to dash dance and the platforms can interrupt chain grabs but also give an opportunity for Marth regrabs/utilt/fsmash combos
FD still exists so that's basically in agreement
Smashville, when the platform is gone gives a decent amount of time to get your chain grabs out, and the platform doesn't really seem to help Fox very much at all imo.
Also I think people constantly overestimate the disadvantage Marth has against Fox on a lot of stages like Battlefield(where I think the matchup is probably still evenish) and warioland seems evenish still to me as well. Marth presumably always gets to ban dreamland(arguably his worst stage still in PM) so I think that Marth Fox is even, or maybe even in Marth's favor on the PM stage list
Ok yeah feel free to tell me why I'm wrong again, or if you think I missed the point or whatever, I'm really looking for discussion
Edit: Player -0, I'm not quite sure what you mean by Fox has verticl powers and Meta Knight doesn't, do you mean that fox has uair combos and MK doesn't? I'm probably just missing something obvious here or i'm being thrown off by the phrasing or my poor reading comprehension
