Re: Yu-Gi-Oh RPG?
Well... if your looking for a good water deck, I would recommend looking at the Gishki. They're an archtype focused around ritual summoning. They have a lot of searching and recycling capabilities and can control your opponents field, graveyard and hand pretty effectively. They are one of the two archetypes I'm considering for my final Deck.
Other than that, you could make a decent Water Synchro deck using Super Ancient Deep Sea King Coelacanth.
That is just about the extent of my knowledge on water decks.
