Is this deck any good? 10 points for best answer!?

yes, finally, someone with a water deck. I used to love them, back when i started playing,but now i ditched them cause they are pretty outdated, since this deck is pretty "clic" (old),you may want to run a few more cards that ociate with umi (a legendary ocean), put in like 2 more mermaid knights, 2 more amphibious bugroth MK-3 (its ok to put more of this in now sincethe old umidecreases all machine types, the new one increases its atk to 1700, an can attack directly).Put in penguin soldier, many people dont use them cause of the unsupported type, but since this is awater deck you should put in a couple of those, there good disablers.Well, thats it, its a good deck, (traditional play)
