Nice post.Loss of Giratina, Gengar, and Moldy Pursuit, along with some other more niche options, really does sting when it comes to Shedinja. Still, I'd be a little hesitant to go after it though less because of any gameplay and more because of general mindset of the population. Has it changed enough since the failed Shedinja suspect for a quick ban a mere 1-2 months later to go through? Or are people just gonna go "lol why r we doin Shed again rofl no ban plz"?
I mean, I'm not opposed to Shedinja getting a looksie this time around since a number of the tools I argued about last gen are just... gone while Shed has picked up more options. I'm just more concerned with people having actually shifted to the Gen 8 Shed mindset.
Personally, I'd say Bolt Beak and Fiscious Rend really need to get smacked out of the meta. I mean, they're effectively 170 BP attacks with 16 PP and 100 Acc with a marginal downside that only really comes up against priority abusers. Yeah, you could outspeed and cut the power and half, but nobody in their right mind is going to be using those moves when they're going to get outsped unless they don't have any better option(s). It's spammable, synergizes super well with speed boosting (Shift Gear, Shell Smash, Choice Scarf, and plenty of more niche options), works for breaking and sweeping, and is incredibly difficult to stall out. They're also about as strong as -ate STAB Boomburst at base power. Add STAB to these moves and they hit something like BP 255. Even unstabbed though 170 BP is going to outdamage most STAB moves. Add abilities and items and nope you're dead. Oh, and they give great coverage with just the two alone.
Oh, and did I mention that, with a little finangling with Dynamax, they can give themselves Terrain/Weather boosts? It's a bit fiddly cause the three turn deal, but still worth noting since any user can pull a terrain or weather boost on demand without warning which can do junk like bypass Unaware and Spectral/Haze spammers.
Do they have checks? Yeah, kinda. Fur Coat helps and so do resists, but they still take annoying amounts of damage from breaker or sweeper sets. Bolt Beak has Ground immunities, but those can be Fished unless they have an immune ability. Speaking of, most immune abilities can be Mold Broken, if desired, and the Ground-types can usually be bopped hard with a Grass or Ice move if really desired. Shedinja stops em, unless Moldy again, and a Sash might revenge KO. I suppose you could Trick Room them, but that's a really niche strat. Paralysis helps, but won't work on the Electric-types and the Paralysis nerf last gen really works in favor for the set-up users.
Compare to V-Create (which might be overbearing this gen too anyway since Giratina, Zygarde, Primal Ogre, and many other fat resists are all gone), which does have more power at 180, sure. But it has half the PP, only 95 acc for random hax misses, and its stat drop drawback make it extremely difficult to sweep with and/or stay in and spam safely which pretty much limits it most reliable uses to wall breakers.
So yeah, I'd say please do Bolt Rend first. Having one, ideally more, resist/immunes on your team is practically mandatory or you're going to get ducked over by a good Bolt Rend user or a spam of haphazard ones. Throw V-Create in there too if you guys really want, I don't care since Bolt Rend is pretty broken.
So after reading all that I decided to test how strong Bolt Rend is. The results are interesting:

Against a noob so nothing worth saying about. However, watching a single Zeraora cheese through 6 Zacian in a row was a rather new experience to me...
