Today's deck is looking to build up a strong devotion to blue while denying your opponents mana and drawing lots of cards. The main way we do this is by casting Sea's Claim and Spreading Seas on your opponent's lands then ramping up with Nykthos, Shrine to Nyx into this guy:

Once you have "spread the seas" of card advantage then it is time to go for the kill with either Master of Waves or even a clever Thassa's Oracle finish. Check out the full decklist and gameplay video below!
