Fusion of the Seas (RUSH series)

Note: This series is based on "Amazon of the Seas", the 2 Fusion Monsters that list it and 2 other monsters as material (which where the first triple fusions in Master Duel), the fellow fusion material, and Umi related cards. Look up "Amazon of the Seas"; "Gruesome Goo"; "Sea Kamen" and "Fairy Dragon" for details on those cards as they are Rush Duel port viable. Zone Eater likely can't be ported to Rush Duel, so Zone Devourer is a substitute.
