Make sure to check my deck profile 1st, as this isn't a traditional Mermail list, so I might not have all the cards you'd normally find. This isn't a common combo, mainly cause you will have more cards in hand besides Neptabyss. It is weaker than what you can do with a good discard (like Dragoons or Squad) or any water in hand. This combo is only if your opponent has nothing in hand.
