Note to self: People appreciate the crazy stuff more. Maybe I shouldn't have edited out the upped Lich after all.
By increasing the ATK, the idea is that the objects are moving from their solitary position to another one, and then they rest. It's like a tide, in that way. A tide doesn't continually move- it goes up, then it goes down, then it rests a bit, then it goes up, then it goes down.
Also, its element IS water.
If you mean make it only use water, then it becomes useless, not even just due to SoPa.
