WATER in the CCG is a powerful attribute. Generic WATER decks usually focus on defense and control but they have powerful counterstrikes. A good WATER deck knows how to protect itself from Swarming, Attacks, and destruction effects. One main WATER archetype is the Tidal archetype.
The Generic WATER Field Spell is Sunken Ship, similar to ALO but also adds a heavier Control element by controlling attacks. The searcher is Shell Statue. Other WATER support cards include Wall of Water, Flood Swell, Submerge and Giant Tentacles, and some cards which could help the WATER cause are Witch of the Deep, Whirlpool Serpent, Turtle from the Sky, Aqua Magician and Icevale Witch.
