I mean, it's probably more of a meme than anything to say that

is a character's best matchup, but all

needs is a single offstage nair/Darkest Lariat... same goes for


, they're very hard to approach, but once you do and get them offstage, it's curtains.

isn't as easy as "just edgeguard", but he hates characters that kill early, and Incin kills stupidly early. And Revenge is a huge boon vs all four. As for more meta-relevant stuff, the cat apparently does decently against

and

. I doubt they're truly winning, but I can see how Incin does better than other mid-tiers and maybe even some high tiers. I personally think Incin does well against

if the Incin player knows how to exploit the matchup: let Olimar attach that Pikmin to you, you can get a Revenge stack each time the Pikmin whacks you. It's a super volatile matchup on both ends, which makes it one of the most fun imo.
In my opinion,

's worst matchups are

,

,

,

,

and

. Projectiles in general are rough for a character with such low mobility (Revenge of course helps) and the Samuses are the worst of the bunch in my opinion. Very heavy (109!) so Incineroar's early kill power is muted somewhat, hard, maybe even impossible to edgeguard since the cat can't go too deep (they have a far-reaching tether as an option, to boot), and the worst part of it all: the tether grab. Revenge is so much more helpful against other projectile users - here, the tether grab gets rid of Revenge for practically free. Approaching from the ground? Grab outranges everything. Approaching from the air? Samus gets to dash/roll back and grab that whiffed aerial. Joy.

and

combo and edgeguard Incineroar for days, and probably have the best non-tether grabs after Palutena (rip Revenge). Though, the chus being light is at least a bit of a saving grace with Incin's excellent kill power.

similarly loves combos and grabs, but I feel like the real issue with him is where is the lag?? Incineroar is a bait and punish character, I can't even punish the dang smash attacks save maybe down smash, which Mario doesn't really need to use.

's excellent combo game is ezpz on big-body Incineroar, his gameplan of camping to get Waft works very well with his great airspeed vs Incin's limited mobility, and he's like, a unit or two lighter than the Samuses, so less easy to get a cheese kill here as well. And yeah, Waft is the big thing that sways this matchup heavily in Wario's favor. You'd rather be a small, light character during Waft combos to be honest; big bodies make the combos easier and don't die to it noticeably later to be worth it.

was just a pocket character for me, but I bumped him up to co-main for the

matchup. I checked some matchup charts made by Wario mains and asked around in the Wario Discord, and Joker seems like my best bet among characters I had already been playing. I don't think Wario is one of Joker's best matchups or anything, but simply, Joker does better than a lot of the cast. I'll probably stick to Joker for this MU, though anyone with Wario experience is free to recommend other characters. This was back before one of the secondaries I've put the most time into,

, received buffs, so now I'm a little unsure who does better vs Wario. It wouldn't surprise me if it's still Joker, though.
As for his best matchups, Joker loves big bodies.







combos for days (though Bowser might be a bit worse of a matchup for Joker since Bowser is much more fleshed-out of a character). I like using Joker against



and

, all of whom have somewhat slow mobility compared to Joker, projectiles help keep them at bay, and Joker weaves around/Rebel's Guard's their projectiles well. They combo well, too.
Honestly, none of Joker's matchups feel that bad. I think he's a well-balanced top tier in his current state - very good vs the cast, but not overwhelming like

or

. I don't think he needs any more nerfs - keep in mind that despite the early kills with Arsene, base Joker will have to wait till like 180 to close out a stock sometimes. That's not inexperience on my part; it happens to MkLeo all the time and he's a far better player than me. I wouldn't be completely against toning down Arsene and buffing base Joker's kill power a bit to compensate, though.
That tangent aside, I know Leo has said that

and

are rough MUs. I can agree with that, both characters have good tools vs Joker. Joker's been said to have a rough time with shorter characters, particularly

,

, and maybe

. I'm not sure if those are too bad; I've found projectile camping vs them can alleviate a lot of the difficulty with hitting them. They're probably more difficult than most, though.
I'll leave this at just my two mains since I've already written a dang college essay here, lol.
