[Wauthan]

Basic Ulm with watercult would not be a good idea since they lack sacred units. Scuba Marignon is a lot more scary. Drive by priesting is though without them storming the beaches. Cheap massable flagellants and though knights of the chalice can take on atlantis and R'lyeh if they have a good blesseffect backing them. Not to mention what submarine inquisition can do in a dominion push strategy.
