Forum:Water xyz deck help

So basically I started out with an Xyz deck that eventually turned into a water Xyz deck. Although Xyz summoning really isn't a problem, I've noticed that I often get a hand of cards that depend on other cards still in my deck to be useful, like A Legendary Ocean or Legendary Atlantean Tridon. Any advice about which cards I should get, get rid of, and to improve my strategy would be helpful.
