Mostly things I've said before, but in 1 post (I may find more good things out in the future but won't add them to this post).
In case some might not know what these mean.
Bair = Back air
Fair = Forward air
F smash = Forward smash
D smash = Down smash
Nair = Neutral air
Up b = Up special
Dair = Down air
Good things I've been seeing with

when I use him is:
His down throw at the ledge, while someone is trying to recover or you catch them at ledge with a grab, down throw acts as a spike and gives characters like

no good chance of recovering, I think it's still like that if you do it on someone at 0% (possibly).
So I guess you can say that

has a 0 to death grab, but have to be really lucky to get it, and hope the character you use it on, doesn't have a really good recovery like chibi robo or maybe

(though you can hit

with a dair while he's trying to set up his teleport back on stage).
He can grab after the 2nd hit of his bair (if you don't hit the 3rd hit and it's on the same plat form as you) or forward tilt (the 3 hit).
I'm still labbing to see what else I can do after the 2nd hit of his bair, it's a really good combo move imo that you should really learn to use/take advantage of (since the 3rd hit doesn't always go I think).
Edge guarding is insanely good, and is a must to learn as a
player.Bair (when you get the 3rd hit) can be spammed till they reach blast zone.
His nair is extremely good too, and it messes with

and

s illusion recovery, tho the problem is, the nair if timed wrong or bad positioning, will send them back on stage instead of back off.
Forward air can actually combo them off stage into the blast zone (I think it can be spammed too).
Also Dimension cape (aka down special) can be used to take your opponent off guard (maybe), for example against

, if you think the

player has enough time to up b back on to a stage platform (lets dreamland for this), you can space your self (so you don't get hit by his up b) and down special to K.O or get him back off stage and do good damage.
This is why I think down special needs to be practiced with A LOT, get the timing right.
I think his up tilt and down tilt combos work REALLY well against

and

.
Though

can't be comboed easily, I think it still takes 2 up air hits to up b (aka shuttle loop) to K.O him (I'm pretty sure

dies early to that combo because of how high he goes when he gets hit), so that's also a weakness

has for exchange of being hard to combo imo.
All the 4 moves I said in the previous post that have weaknesses, can also be of really good use, but you need to practice how to use them and not just throw those moves out there expecting something great to happen (cause it usually wont lol)

DOES NOT like fighting strong up air and up b characters like

,

,

etc.
BUT! imo,

has a really good punish game. For example against

, his up air is good, but if you learn to air dodge fast fall, you can hopefully catch him in the air with a up air string to up b. Idk if this would work same against someone like

(pretty sure not against

), so yeah lol.
Also, when they DO hit you with an up air, try to fast fall dair to stop their attempt to up air you (don't know yet if it stops

s up b) or try to fly away but be sure your at a good distance to fly away so another up air wont hit. You can't air dodge right after up air hit (or any hit I think) so yeah. Maybe as soon as you do your jump after the up air hit, you can try to air dodge quick before another up air hits you (maybe).
I would mostly suggest fighting against characters with strong up airs on the ground, and not fly around so much.
When coming to fighting projectile characters like

and

, At-least for what I do, I fire ball and bait with up smash or up airs.
I think trying to bait that out, and fast falling to maybe dair or fair, is a good way to probably get in? Well it's something.
Because

has flight, I say maybe let them keep spamming projectiles and fly around them, but make sure to watch out for them to probably fair or up air like

may do. Flying around projectiles is a good thing

, don't bother shield against them, imo shielding as

kinda suks.. kinda.
When it comes to fighting projectile characters as

, imo it's better to fly around them then shield when they are spamming projectiles.
You can still sometimes try to shield then grab them and up throw (which usually mostly only kills around 155+%).
His up throw is a cool funny SD move that can take away both players stocks with them not being able to escape it (maybe unless

bomb can still activate like in ssb4, same with

)
I think

neutral jab (not the forward tilt) is a good move to stop momentum, but remember that you can't spam the neutral attack because people are able to grab or attack you out of it (just like tornado, but idk if they can grab you out of it lol).
I think neutral attack could be a good edge guard tool to stop their second jump or make their flight shorter, and makes you able to go for a f smash maybe. They are able to grab after the 3rd or 4th hit I think of the neutral jab.
Don't over estimate his recovery, he has multiple jumps yes, but his 4th and 5th jump lose have lower height than the first 3 jumps, and even with up b, it still is a hard recovery for

for when he gets spiked, so be careful.
His down special can be used a run away to safety move sorta, just don't do the slash if you think they wont get to the spot your trying to teleport to at the right time, cause not doing the slash when you down special causes less lag.
Try practicing side b and his 5 jumps to up b on the ledge. Idk if down special is a good idea to use to get back to the ledge, cause you can sometimes end up SDing instead of reaching on stage or the ledge with down special and I feel same way with tornado. So when recovering, I'd just mostly recommend just using side b to ledge and his 5 jumps to up b.
Some people might be like me and have a habbit of where they would up tilt to attempt trying to combo them after they get hit by it, but you just end up staying on the stage/plat form and keep doing up tilt, so yeah, it's good to practice to dash attack and up tilt and get off the floor and try to combo, unless of course your fighting someone like

or

where you could go for something else after the up tilt like maybe down tilt to another up tilt to f smash or another down tilt.
Because of his 5 jumps, you can maybe play mind games on the ledge.
His back throw is really good, he can hit right after the back throw which allows him to have a chance to up b (so basically can be used as a kill setup for up b or up air string to up) He has a chance to do this because, after he hits them right after the back throw, they are forced into the air and they stay up there long enough for you to do it,
but they are also able to move out of the way so you may not be able to catch them. Sometimes they might not go so high in the air, but you can still fair.
His down throw is also good for trying to combo like, down throw to down tilt into something else, but they can roll the opposite side of where you facing so you would have to guess. But sometimes when I predict the roll, I usually bair and get the 2 hits from it into another grab, or do something else when predicting the roll, but I think the bair is good.
His up smash doesn't kill anytime soon, but can be used to send opponents back into the air to continue combos or start them (maybe not at low percent to start).
So again, main things I think most

players should first learn to do (maybe not first) is, practice up air string combos, back air combos (after the second hit), down special timing, recovery, teching, up tilt and down tilt combos, and stopping the neutral jab to try grab, hit or run away, shield droping and back throw setups.
I might be wrong about some things, but feel free to correct me if I am

.
Btw, anyone know a good combo that could lead into

s tornado?
I hope this post helps people who wanna use

but not sure about things he can do.
Edit: I think someone might do a take a shot everytime I said "I" or "maybe" challenge here lol.
Edit 2: I don't mean for this post for people to read it and think I mean you should play

in only 1 way, but you can take ideas from this post and maybe mix it into your play style if you find yourself struggling with certain things too.
