My quick thoughts on this list:Among the things to suspect test, we have Dynamax, Darm-GZ, Intrepid Sword, V-create, Fishious Rend, Bolt Beak, Octolock.
-Dynamax: While it can be annoying to deal with, Dynamax is a staple of Gen 8 and it would feel wrong without it. Maybe set a cap though, ala mega evos.
-Darm-GZ: Eh, idk. They seem like a powerful sweeper force, but there are many powerful sweeper forces in the meta who are fine; If we nerf their kit, however, specifically V-Create, they can be introduced into gen pop with little to no problem.
-Intrepid Sword: Not only is this the signature ability of sword doggo (and they would feel wrong without it), but there's also similar abilities like Speed Boost and Dauntless Shield. While Attack boosting per turn is obviously better than some Abilities for sure, it might not be banworthy, but idk.
-V-Create: Kill it with fire.
-Fishious Rend: Kill it with water.
-Bolt Beak: Kill it with lightning.
-Octolock: I don't see too much of a problem with this one, but I haven't ran it or fought against it enough. However, it seems to function similarly to moves like Fire Spin, but it lowers Defense. I could see why it's broken, but I don't think it's quite banworthy. Maybe put a "No Intrepid Sword + Octolock" clause though, that seems a bit wack.
