Master of Waves could work since this deck has alot of blue devotion and it's also a wizard which will be good with this deck.

yeah, i'll test it as soon as i get my hands on one, thanks for the suggestion

High Tide ? Caged Sun and Gauntlet of Power ?

i've been thinking about testing high tide, i took out gauntlet and sun because they are too slow for my meta

Arcanis the Omnipotent or Echo Mage ?

They are too slow for my meta, Echo mage would be killed before even getting to level 2, and i don't think arcanis would survive a round, and my games usually end before i get to 10 mana, so i couldn't protect arcanis with it's own ability
