Definitely need Nightviel Specter into the deck. Not only is it 3 devotion to both blue and black but it also let's u play cards from ur opponents library and is a 2/3 flier.

Agree, the Nimbus Naiad 's will fly away as soon as I can out my hands on a playset of Nightviel Specter

if it is a devotion deck you need 4 Master of Waves he is the main card in the blue devotion deck

I have a blue devotion deck and i am trying to splice in another color. if you wantto see how i am trying mine here it is Mono Blue spliced with green

4 Master of Waves are on the pipe line too. You dont have and idea of ow hard is to found cards aroun here.

Jace, Architect of Thought ?

Another win condition. If Im facing a too control deck that did not allow me to drop bodies and mount and attract Jace AT and Ashiok can give me the game by Milling the opponent deck. Ar thats the idea anyway...

Would look for more Cyclonic Rift they are pretty much an answer to everything, though I would move them to the sideboard. And then fill up with Hero's Downfall

So 3 Hero's Downfall in the main and the Cyclonic Rift to the Sideboard?

The deck looks awesome now! Defintively soemthing I could try out!
