I would personally be opposed to implementing Nickname Reveal Clause. If you look at your opponent's team, you can usually get a good idea of what kind of sets they're running. If I see a Qwilfish on a stall team, I know that it's probably a Clodsire, and even if it isn't none of its other defensive sets are handled that differently. If I see it on a hyper offense team, it's probably a Ceruledge, and typical Ceruledge answers also work well for most of the other offensive sets it can run, and even when your counterplay is different for the different offensive sets it runs, you should be prepared to fight against any of the sets it can run, and once it gets sent out you know what you're facing. There's also some Pokémon that only really have one set that they can run, such as Electabuzz only running Vivillon sets. Even if you're surprised by a Pokémon that your opponent is running, you can only get surprised once, and you'll know what to expect in future games against that team.
Cloyster was mentioned as an example of a Pokémon that Nickname Reveal Clause would help with, but I think that it should be banned anyway. Mudbray Cloyster is not very common at all, but it is very powerful. Although it only has 130 Atk, it compensates for this with Shell Smash, the ability to run an Adamant nature, high BP attacks, and Ground/Ice coverage. After a single Shell Smash, Mudbray outspeeds almost the entire tier, can OHKO most offensive threats and will 2HKO them if they survive the first hit. Mudbray also has 90/150/75 bulk, which makes it very difficult to revenge kill, especially if screens are up. If screens are up, Mudbray even beats Magneton Hydreigon 1v1. The combination of Shell Smash and Mudbray's coverage also makes it difficult to handle defensively. Dusclops can deal with it, but it's inconsistent, especially if Mudbray has Substitute. The only reliable way to deal with it is with a Slowpoke, which only fits on Stall, and even then, depending on what set it runs, it can't afford to take much chip damage in order to deal with Mudbray.
I can see the appeal for banning Qwilfish Ceruledge, but I don't agree with it. Most physically defensive Pokémon that aren't weak to a move it runs can handle it in some capacity, though how well it does depends on the Pokémon. Vullaby, for example, hard walls even Taunt sets, and although Gligar loses 1v1, it can at least U-turn out into something that can deal with it, and it can guarantee chip before this with Earthquake. Non-Taunt sets don't have a very good chance at breaking well-constructed defensive cores. Dealing with it offensively is also completely manageable, though how you accomplish this depends on the team. For example, you can Volt Switch on it with Vivibuzz and send out your own Ceruledge to block Bitter Blade. Depending on the set, whether they read the switch, and whether you win the speed tie, you may or may not take it out with your own Ceruledge, but even if you don't, Ceruledge will be at too low HP to take on anything else. You were forced to trade your Ceruledge for theirs, but that's fine because that was something that you accepted when you built the team. Ceruledge's Speed is also not an issue because if you can't outspeed 135 speed, your team is very slow. I do admit that Ceruledge will somewhat frequently 6-0 teams, but that's not because it's broken. That's because your opponent is using a bad team that has 0 Ceruledge answers (I don't know why this is such a common building mistake). I can't comment much on Shadow Sneak sets since that's a very uncommon move that I don't have much experience facing, but I haven't had any issues with it when I have faced it.
Clodsire is definitely not broken. If you can't break past it, you just simply have an ineffective breaking core. Toxic is annoying, but that isn't a good reason to ban this, and most of the Pokémon that run Clodsire learn Toxic naturally anyway.
