R/F Water Deck

I'll give this a try:)

Monsters:
-1 Kaiser Sea Horse(you make monsters less tributes already)

+1 Warrior of Atlantis(great key card searcher)
+1 Sangan(I think you forgot him:)
+1 Colossal Fighter(great synchro)
+1 Ally of Justice - Catastor(anti non-dark)
+1 Red Dragon Archfiend(anti defense decks)
+1 Magical Android(heal beatstick)
+1 Armory Arm(with lvl downgrade this card is easy summon)
+1 Iron Chain Dragon(anti Lightsworn)
+1 urbellum(slows opponent)

Spells:
-2 Water Hazard(not great)
-1 level limit area B(stops your monsters)

+2 Moray Of Greed(great draw engine)

Traps:
-1 Metal Reflect Slime(really wanna use it?)
-1 Mirror Force(swapping for Torrential Tribute)

+1 torrential tribute(great card)
+1 the Transmigration Prophecy(affects opp grave too and re-uses key cards)

I hope that helps good luck on your deck:)
