I think he's solid but not top tier.
He has some slow-ish moves and some moves that are surprisingly quick. He's got a decent toolset, good aerial movement, two useful meteor smashes in DAir and FAir (there is a meteor hitbox in the move), and he's a decent weight. He's really agile and has a great dash. His range is ridiculous, which was to be expected when you're carrying such a giant ass sword.
For specials, Climhazzard sucks as a recovery but LB Clim is disgusting as a kill move. Finishing Touch has some good applications as well. Being able to charge Limit Break is a plus despite the fact I didn't think it'd happen. Cross-Slash is kinda meh, I was hoping it'd aid his recovery but it doesn't really do anything in that regard, though I do like that it connects very well. Still was at least hoping for a Dancing Blade-like function where it could be continued without Limit Break's aid if you continue to press (which it doesn't).
His aerials are pretty much all great, I don't think many people can easily challenge him in the air. His UAir can kill and has a great, lingering hitbox much like TLink who also has a great UAir. His BAir is quick, his NAir covers a huge range.
Smashes are great, his DSmash is really fast for a smash attack and can kill at reasonable percents, his FSmash has good range and makes a good punishing tool, and his USmash is pretty quick even if it doesn't doesn't cover as much range as, say, Ike's.
Throws aren't that great, UThrow is good at low percents to create follow-ups and BThrow can toss people off-stage for edge-guarding, but DThrow doesn't really create a chance for decent follow-ups and FThrow isn't anything all that special.
Jab is great, it's fast, deals decent damage, and leaves some room for a follow-up. Dash attack is your standard dash attack I think, nothing too bad, nothing that good. Definitely better than most characters I use personally.
Overall I think he's good. No extremely glaring weaknesses outside of bad recovery, but I think he'll be a decent fighter with decently-linking attacks and a strong mixup game. I like him, he's certainly not as good with combos as Ryu, Pikachu, Sheik, Roy, etc., but what he's good at, he's GREAT at, and what he's not so great at he can cover up decently with his options. He's not top tier at all, but I think he's solid. I'm sure he'll perform pretty well.
