Tossing in my 2cents...
Tilt Moves & Jab:
Jab- At high percentages, it can cause them to get knocked towards the ground, allowing for a tech chase. I find it useful to use when wavelanding onto the stage as a safe-ish recovery option or to pivot/turnaround jab to catch people off guard.
Utilt- If i'm approaching with a fair and I already see the shield>shield grab scenario playing out soo, I'll try to move as far away as I can, fast fall, then go with a turn around uptilt to get out of their grab range and if they get hit, try to continue into a quick combo.
FTilt- Faster alternative to an FSmash for edgeguarding if they're recovering faster than you expected. I mix it up with the jab when wavelanding back onto the stage to recover.
*DTilt-I just want to say that it's easily crouchcancelled/teched at low %s if the person knows the matchup even vaguely, similar to how Falcon's Raptor Boost can be teched.
Smash attacks:
USmash- I find it useful to use if someone's coming above me, the disjoited hitboxes help out a lot in cancelling aerial approaches from characters coming from straight above you.
FSmash- Pivot FSmashes are your friend after a good dash dance +wavedash approach/retreat. Useful to throw when baiting someone to approach you.
DSmash- Double Scoop. A good kill move if your opponent is at high % and you're at a low %. Relatively easy to CC into it. I'd have to look into how it works as an edgeguard.
Aerials:
Nair- Good to approach if mixed in with other moves. Good to get onto platforms with. Mixing up getting only the 1st and getting both hits in is a solid option to work with
Uair- I use it to get onto lower platforms like those on Fountain of Dreams or Battlefield or even Stadium at times. It can lead to some kind of platform game if it connects on your opponent and they land on the platform.
Bair- I'll use it when moving away from my opponent since the move is out for so long. Sometimes I'll use it for edgeguarding by having them fly away just a little bit and prep for a FSmash or other kill move from there.
Fair- Full jump double FAir, this with DED mixed together is an interesting approach. I'll use it while fulljumping and retreating onto a platform sometimes.
Dair- DTilt >DAir is solid. If I DTilt them under a platform and get the DAir when they're above it and get the sweetspot, I can catch their roll/tech inplace with a grab or an FSmash. If they getup attack, Grab. If I'm on the ledge and they're recovering from the bottom, it's not too hard to get the meteor smash on them while you ledgehop DAir back onto the stage. Very small window to do so though. If you wait longer, you can ledgehop DAir without getting the meteor smash and go into a FSmash as they'll be lifted up a bit.
Specials:
Flare Blade- Double Full Jump Flare Blade, interesting edgeguard option, it's long range is also a good way to reach characters who are trying to camp you out or just barely knick you.
Blazer- It's underestimated recovery in my opinion. Having a more noticeable angle change that Marth's recovery makes up for his fast fall speed I think. You have a lot of places to recover from compared to Marth. If my opponent isn't already on the edge, I can pull out a horizontal blazer and catch my opponent as they're jumping or wavedashing towards the ledge. Being able to have either a vertical Blazer or a horizontal one helps when I'm trying to get 'onto' the stage rather than grab the ledge, especially if they're already on it. Mix in another DED or go straight to the 2nd DED chain will cause me to sink faster so I can mix up when I actually use the Blazer.
Counter- Mix it up with a short hop DED, Full jump into a fair then fast fall into a Counter. I replace a move I usually approach with or defend with as a counter sometimes. Edgeguarding tool. Needs to be used more often/better.
DED- I don't know if anyone else does this, but if a character is at high enough %, I can short hop DED, wait it out, and before landing toss out a FAir to be like Marth and his short hop double FAirs., I feel that I've never seen this and felt it was something new enough to point out.
Grabs:
Pummel- No Comment other than it's not as great as Marth's. I'll pump it out at higher %'s, and maybe once past 15% maybe.
UThrow- Kill move at high %'s. No one expects you to go for a grab>Uthrow and then die. Good as a kill move if you've gone past that % where you can't DTilt>FSmash or any other two hit move. Spacies, I can chaingrab like Marth too!
For B,F, and D, nothing notably different from everyone else.
Advanced:
Reverse Neutral B- Edge drop with it as an edgeguard.
Wavedash- I'll wavedash/dash dance towards me opponent, stay crouched for a bit then turn around UTilt. A really nice and low wavedash and dash.
Waveland- Fast and smooth, useful if you're crouching while wavelanding as well to dodge out any attacks above you.
