Firstly, you have a lot of Fairy weak Pokemon with Umbreon, Dragapult and Dracovish. You do have a resist with Cinderace, but I'll get to that.
You also don't have anything for opposing Dracovish which is just begging for trouble.

Power Trick and Rollout on Shuckle is a fun gimmick, but Shuckle is too slow for it to really work, even if your opponent has been Sticky Webbed. I would recommend you replace them with some combination of Toxic/Infestation/Final Gambit for a suicide lead. Use a Sturdy Shuckle instead. You might also want to consider Mental Herb over Rocky Helmet since longevity isn't necessarily the point with these changes and you'd get screwed pretty badly by Taunt.

Putting an Assault Vest on Alakazam is wasting its potential. You lose access to Nasty Plot, one of the best boosting moves, and also Recover which is arguably even better since it provides you with longevity. Instead you'd be better off with a Focus Sash to help you get Nasty Plot off or Life Orb to maximise damage output. If I was going to be willing to sacrifice access to Nasty Plot/Recover, I'd consider doing it only for Choice Scarf so I could outspeed Dragapult/Zeraora.

Umbreon here feels like dead weight. It can function as a Dragapult check, especially with Sticky Web up. But I think Mandibuzz would do this job better since it could provide you with Hazard control in Defog if you need it, Foul Play for Dragapult, more reliable recovery in Roost and then your last slot could U-Turn for momentum, Knock Off for Utility or even Brave Bird but eh. I'm assuming that Thunderbolt Dragapult isn't super common here though.

Cinderace is wasted without Librero. Yes, it's a solid physical sweeper, but you're losing out on both extra power and versatility by going for Blaze. You're also leaving a big gaping Dracovish weakness open here. Personally, I'd consider switching it for something that can reliably handle Dracovish.

I'm not familiar with the meta for SwSh ranked battles, so I've done the best I can. I can see what you're going for here, but honestly I think the biggest issue you'll face is that your team is kinda forcing you to choose between which threats you want to check. You could try switching Umbreon for Corviknight which would free you up to swap Cinderace for a bulky Water Absorb mon that can handle Vish without you being dependent on Sticky Web staying up. I think either way you're going to have to take some calculated risks though.
