My current opinion on the tier list:
Justification (keep in mind this is all imo, I don't mean to be stating this **** like it's irrefutable or unanimously agreed on):
-Ice Climbers are not a step above Diddy/Olimar/Snake. Just... no.
-Snake is underrated at the moment - his Olimar mu is nowhere near as bad as people claim (look at Japan if you want to see why), and people seem to be pessimistic about his mk match-up recently as well, which seems more like people ******** about how Snake gets punished hard in the mu and ignoring his results (which always have and still do indicate that he does
very well in the mk mu).
-I'm not entirely sold on Lucario being a tier above Wolf (mostly because of his worse mk match-up), but not having significant trouble vs. wario, dedede and pika is pretty nice
-Toon Link's mk match-up sucks. That's about all there is to it lol. I'd put him as equal to G&W probably, I can't ever decide who's better. Fox is super nice just because he does amazing vs. mk and absolutely fine vs. EVERYONE else excluding a horrific ICs mu and a pretty terrible pikachu match-up.
-G&W is underrated vs. Diddy and ICs, they are both -1 as long as you platform camp intelligently. ICs actually have no way of approaching G&W on a platform (if he shields uair, he can up-b and launch ICs into the air with the wind-box, regardless of how well-spaced the uair is - it's a pretty big deal).
-Dedede is so overrated, waaayyy too many bad match-ups to be as high as he is (especially since two of them are mk and ICs)
-Kirby is overrated, same reason as D3 but all of his mus look better than they are because kirby is good at making games go to last stock (but then he can't KO cause bair is stale - this isn't even hyperbole, bair is kirby's only option in soooo many situations and he can't KO without it. His best mus are ones where he can refresh bair, or he doesn't need it to KO, otherwise he has to die to refresh it lol). I may have placed him too low in retrospect, but eh, the order of the characters in this tier could really be jumbled in any way
-Lucas might be better than Ness, I dunno
-Jigglypuff is underrated as ****. She does decently against ICs, Olimar, Diddy, Falco and most of the upper mid tiers, loses harder to a few characters (marth and snake, most notably), and gets destroyed by mk - that's a better mu spread than mario's multiple unwinnable match-ups lol. You can argue her match-ups if you want but ask yourself how well you really understand this character, and how much weight your opinion carries - I'm not saying my opinion carries any weight mind you, I've never achieved anything, I'm just saying that your word is as good as mine.
-Zelda/Ganon is a toss up but I think Ganon is better just because of how hard he punishes mistakes. It's easy to say "oh I can just do this and not lose to ganon" but then you slip up once and get hit by side-b > dair > uair and you've suddenly gone from 10%~ to KO%. Zelda is similarly exploitable, but she doesn't have that factor.
