As the title says this deck is all about the Sherean Leviathan and giving him the flying trait (if possible for the whole game).
A flying Leviathan in a shallow sea is just epic. First of none of the enemy creatures can melee attack him, beacause they all get restrained and therefore loose the flying trait. They also can be ignored while guarding out of the same reason which allows my Leviathan to attack whichever creature I want to. Because of unstoppable he cannot be pushed out of the zone which in combination with Astral Anchor means that it is very hard for the enemy mage to get his creatures out of the “death zone”. Even if the Levi is attacked with ranged attacks he is protected very well because of his 3 armor and his tough -3.

My normal opening is:
Turn 1: Double move and cast Ring of the Ocean's Depths
Turn 2: Cast Leviathan and enchant him with Eagle Wings
Turn 3: Teleport him (if necessary) to the opponent mage or even better to his spawnpoint if he has one and cast Shallow Sea into his zone

Turn 1: Move one zone and cast Mana Crystal and Leather Chausses
Turn 2: Move one zone and cast Ring of the Ocean's Depths and Leather Boots
Turn 3: Cast Leviathan and enchant him with Eagle Wings

From this point on I try to get all the enemy creatures into the zone with my Leviathan by using push effects (attacks and Force push wand), teleports and chant of rage. To prevent my opponent from teleporting either one of his creatures or my Leviathan out of the zone I enchant it with Astral Anchor. With Bear Strength on it and therefore 10 attack dice (+piercing 2) my Leviathan will be able to knock out one small creature every round. Bigger creatures get also killed very fast (most of the time I need 2 - 3 rounds). With healing spells and purify in addition to all of his protection I prevent my Levi from getting killed. In a longer game I also have the opportunity to bring out some other creatures such as Naiya to give me more actions and mana. Once the majority of the opponent creatures is killed I focus on the mage e.g. by tanglevinig him and attacking with the levi, my other creatures if I managed to bring them out and my mage (Attack Spells and Trident).
If the opponent uses many creatures Tsunami can combo pretty well with the restrain-ability of the Leviathan. Just cast it when most of the creatures are trapped in the “death zone” and you will get a very high amount of attack dice.
The rest of the spells is just standard stuff and/or helps to support my main strategy.

Please let me know your thoughts about my deck. I’m glad about every advice you can give me!
