Gonna make a fairly biased speculative tier list (and probably edit it 40 times immediately after posting), if only for my personal reference while on Salt Mines tonight. Characters are in order - left is better; but that doesn't mean I'm right about it or that I have any business ordering them that finely.

Misc. Justifications:
- CF has always been extremely dumb. The lack of other dumb stuff will make him shine (heh) more than ever.
- Ike is one of the few characters that does well against spacies - he can also wall out floaties, catch up to fast runners, edgeguard the hell out of anyone, and is extremely difficult to edgeguard for many characters. I don't think Ike has many, if any, significantly losing MUs - that disjoint and speed is really insane.
- ROB is still stupid good, just a bit less stupid now.
- Ditto with Roy, far as I can tell
- Mario still ridiculous. Tools for every situation, fireballs are still nuts, has tons of kill setups and solid edgeguards, and his dair still beats basically every move.
- MK is fastgoodstuff on a stick
- Yoshi still isn't unlocked. I'm working on it, slowly.
- How much was Lucario actually nerfed?
- M2 also not yet unlocked.
- Marth is Marth
- As everyone else gets worse, the Year of Luigi cycles back around again. Also it's becoming more and more clear how hard it is to punish and edgeguard him, especially with respect to how well he does those things to everyone else.
- Snake buffs wow holy crap
- I know SB disagrees, but I still think GnW is very strong. He's extremely tough for a lot of chars to deal with still, and a 3 frame upB that gets you out of combos and combos into other things of your own is still completely insane.
- Pit feels cool. A tier is basically "I hope these guys are as strong as they feel" tier.
- Yeah, I overrated Ganon before. Big characters are flawed.
- I'd need to talk a bunch to Boiko to get a better feel for Ness's placement, but he seems stronger to me than before - and with a proper control setup, he's not as bad as everyone thinks.
- Ivy is a bit better, but still furiously mediocre imo.
- Is Link actually this bad? Tough to say.
- Big characters are still kinda awful. Bowser is worse. Squirtle is so, so far from being unlocked that he still may as well not exist - though I do believe the potential is there.
