I will answer your question here to avoid derailing the thread any further. There is no restriction on Leader's Choice winning OM of the Month; it can do so immediately, the next month. You are correct that my mind is made up. However, there is no superior that can change my decision.
To respond to your quote from the Identification Thread, I could've finished making an RMT which featured Hydreigon before the Suspect test begins, but I didn't manage to. I can continue working on the RMT if Hydreigon remains in UU.
I always was of the opinion that complex bans are taken as a last resort not a 2nd best option, as it currently is being used. I can't get behind the let us add another mon into the game even if technically it will fall into obscurity due to being nerfed.
