W A T E R D E C K

Not necessarily good, but always fun.  Haven't figured out the Extra Deck shenanigans yet, but the main deck focuses on slappin' down monsters quick.  Diva is a free pull for Tridon, and the two of them deck-search Poseidra.  Dragoons and Attack Squadron ensure that you can punch through walls if needed, Infernalqueen pulls Terrorking for free from essentially anywhere, and Mare Mare goofs about with levels to work into Synchros and such.  A Legendary Ocean changes the ballgame -- Abyss Soldier, Dragoons, Megalosmasher, and Blizzard Falcon/Dragon swing under Gravity Bind; Terrorking/Infernalqueen and Shark Cruiser become freebies; Mare Mare and Poseidra are one-Tributes, and Mare-Mare can drop hard enough to slip under Gravity Bind the turn it pulls up; and all of your 4-stars become valid for Acid Golem.
