Ban king's rock from PvP

There's no need to explain why, it's frustrating to play a PvP, be about to win, you still got a counter vs Cloyster, and then, from nowhere, when cloyster just sets up Shell smash, tada, you get flinched!   It's literally one of the most unhealthy PvP items. For those who say that "King's rock is ok 'cause paraflinch exist eksdee", paraflinch can be stopped by lots of things like natural cure users, electric types, or heal bell cleric users, while king's rock cloyster is just a spammy
So my counterplay to not getting lucked to death is to use a low distribution priority move from two unsplashable mons and hope I don't get lucked to death by ice shard flinches on one. The only reason walls are more likely to get flinched is because they are the only mons that may survive a 125 BP nuke from a Pokemon at +2 attack
