Lonely Ghosts, floating above the sea.
Nowadays they whirl up the waves with their ladles, sinking ships into the ocean in search of new friends.
Explanation
It has a fast ability to increase a Water-type unit's level and a trigger ability to discard a card from your deck when another one of it is summoned.
As a special rule, you can also put four of them into your deck.
Since its stats aren't that good, you'll mainly want to use its abilities instead.
The first one lets you increase the level of a Water-type unit before retiring it, increasing the amount of mana you'll get back.
You could also use it in combination with effects that get stronger depening on the level of your units.
Therefore it's quite a versatile ability that can be used in many decks with Water-type units.
The second ability lets you discard a Water- and Ghost-type card from your deck.
Since both Water- and Ghost-type cards can often make use of cards in your discard pile, it's easy to take advantage of this effect.
But as it requires you to summon another unit of the same name, you'll probably want to have 4 of them in your deck to make that easier.
