We are out of beta and starting with the retest for real now. However, we have decided to do a last batch of bans due to drops and new ladder trends, and this time we included the rotating council. Aquadext, Killintime and @Sacri are the first members of the rotating council.
The following Pokémon were nominated and voted on by the council
Azumarill, Drizzle and Thundurus-I are being sent to BL. Reasoning:

Azumarill, Drizzle and Thundurus-I are being sent to BL. Reasoning:
Azumarill has been a centralizing force of the meta for a while now. Its Choice Band set is nigh impossible to switch into safely, and on top of being a great wallbreaker, it boasts strong priority allowing it to revenge kill and potentially clean. Even though its speed is low, it has a good defensive typing and decent natural bulk, letting it put in work against any kind of team. In addition to the Choice Band set exists the Belly Drum set, with either Sitrus Berry or Normalium Z, which serves as a great lategame wincon. Even without a Choice Band, an unboosted Azumarill hits hard so it is not reliant on set-up, either. On top of all of this, dealing with both sets differs: while Choice Band sets can be walled by some Pokemon such as Amoonguss, Belly Drum sets are usually revenge killed, so guessing wrong between the two sets can open up holes in teams. For all of these reasons, Azumarill has been banned.
Just like Azumarill, it is impossible to take on Thundurus safely. Between its mixed set utilizing z-Fly and its several Nasty Plot sets featuring Life Orb, Electrium-Z or Fightinium-Z, there is no one safe method of dealing with this Pokemon. Although it relies on either Hidden Power Ice or Hidden Power Flying for many of its sets, either of those in addition to either Grass Knot or Focus Blast accounts for the entirety of the metagame. While Thundurus is weak to Stealth Rock and does not boast the greatest bulk, its speed tier more than makes up for that, as there are only 8 Pokemon in the entirety of UU that outspeed it. Between its great speed, raw power and stellar coverage, Thundurus has been deemed to be too much for UU.
With Kingdra dropping to UU, Rain-based teams received a large boost in viability. Rain has already been very strong, and with the addition of Kingdra, it became significantly better. Kingdra's typing has great offensive and defensive synergy while its stats allow it to run physical as well as special sets. This malleability allowed Kingdra to make up for the flaws Rain had before its drop, and a lot of teams just lose to Rain at team preview. However, Rain itself is not the issue. If a turn has to be given up to set up Rain via Rain Dance, that can either be prevented or exploited. There is no singular Swift Swim user that is broken. Lastly, Damp Rock is not in itself a problem, as it is not broken in conjunction with Rain Dance. As such, Drizzle has been identified to be the issue and will subsequently be banned.
