It's rather simple, some inclusions could be Octopus, Basilisk Blood or Earth Nymph, Quicksand, Congeal and some other useful cards from those elements. Just seems like it's a second Divine Glory where its just a rush with some control thrown in. Actually if you improve on this enough I wouldn't mind seeing this as an improved Neptune deck. He's just to easy because he's got horrible control, especially since he can't use the Tsunami.
