"Gholdengo is the reason Great Tusk is at 50% usage on ladder and over 80% in tournaments"
Did you misspell King Gambit?
Kingambit is where he'll get the other 50%
The only thing I'm wary of is that given Volcarona's controversial ban, the approach might raise some questions unless the Supermajority is a particularly high shut out, since "Uber dropping" vs "OU leaving" would change which side needs the 60% vote to get their desired result, which is DEFINITELY going to raise some hell if it ends up staying Uber with a 58% "Unban" voteIts most definitely a volc suspect test cause it is a controversial ban and the only closure the council will get is whether they prove themselves right via the test failing to unban, or via volc getting unbanned and them proving they listened to us by letting us have a vote ourselves.
Only way I can see it not being volc is if we do tera first (preferred personally, cause volc is a definite unban on one of the outcomes of that anyways and its an inevitable test we need to stop procrastinating on.)
