Thanks to everyone voting! Due to a very one-sided vote, there's already a guaranteed supermajority: With 40 ban votes and counting, Melmetal will be banned from SS Doubles OU.
The voting breakdown is as follows:
BAN: 40 votes (63%)
DO NOT BAN: 2 votes (3%)
Not Yet Voted: 21 votes (34%)
Thanks to all who participated. With the vote taking less than 6 hours to reach a result, I'll leave the thread open until the deadline in the OP for the many voters that haven't yet had a chance to cast their votes.
