Azumarill is stopped by Jellicent. Every Azumarill, any Jellicent.
The new guy Kyu-B is fairly good in this regard. Compared to Hydreigon it is more specialized in taking down bulky water, thanks to Fusion Bolt and the Ice resistance (Edit: before somebody picks on this: I am referring to its Ice type; all in all KyuB is neutral to Ice). It is both an adequate mixed and a brute force wallbreaker.
CB is pretty straight forward. Select the appropiate move and watch things die. The only things ever to appear in this tier and not being 2HKOed are physical defensive Forretress and Bronzong, who both don't have active recovery.
But since its sparse physical movepool is one of the main reasons it is here in the first place it may be wise to dig in its special selection. There is no wall who does not fall within two turns (if there is, please tell me - sounds useful).
