But if Broken is checking Broken per this description, shouldn't that be more reason to vote ban on Volcarona who you already said you'd want to see go if not for checking Kyurem, which you also think is bad? Like if we're at a hypothetical deadlock of busted mons checking other busted mons, removing one would theoretically lead to a much stronger case for the ones they were checking in the subsequent meta (EX: If we remove Volc, Kyurem loses a common check and suddenly that 58% becomes a 70%).
Some people have this logic for checking mons that they think are extremely strong but not banworthy (like Kingambit as a Ghost check for Gholdengo and Dragapult), but if you think Volc and Kyurem are both unhealthy, it follows to remove Volc even if you think it's the less pressing of the two.
I think you make a good point and I would say yes, but 1) I don’t believe the council will test Kyurem again 2) that assumes top players agree with me. Which they don’t.
I think realistically if Volc goes, Kyurem would just be more broken and nothing would be done about it.
