In this new deck I'm trying to create a semi-viable way to summon the legendary fisherman into the field, using the effect of the crystal girl, it allows you to draw a lvl5+ WATER monster from the deck at the end phase, so the best way to use it is by tributing it with one of the mermails, abyssmegalo or abyssteus, or with citadel whale if the crystal girl is on the field, so in the end face yo can bring the legendary fisherman (I or II) and in your next turn if you have a lvl5+ water monster on your field you can spc.summon her again from the graveyard, activating her effect and allowing you to bring the legendary fisherman III, if the crystal girl is not on your first hand but you have, deep sea diva, you can activate her effect, bring neptabyss, then tribute atlantean dragoon, and bring another atlantean dragoon, with the dragoon bring abyssmegalo or the lappis dragon and special summon them, and after that you can use the deep sea diva and the neptabyss to bring abyssalacia from the extra deck, this card will allow you to:
a) if you have dragoons, marksman, or infantry in your hand, use them in the enemy turn for, search one sea serpent, or destroy a set card on the opponent field, or destroy a face up card on the opponent field, also bring one mermail in add to your hand that could be abyssteus
b)if this card is destroyed and sent to the graveyard by your opponent effect or cause your opponent destroy it in battle, you can throw one water monster from your deck to the graveyard and then special summon one water monster from the graveyard, yo can use this for throw the crystal girl and bring it from the graveyard for activate her effect in the turn of the enemy, or if you have the field bring the citadel whale and since it was special summoned you can bring the sea stealth attack from the deck to the field, or if you have the legendary fisherman III in your hand, use her for bring the legendary fisherman II
I heard some of your recommendations, so i made the deck a little bit small reducing some non very important cards and also i add some more synchro in the deck that could be more useful in more situations
