I am starting to think UW Affinity is the right way to go. I am glad to see the deck is getting more attention. I am planning on testing this list next as it seems strong all around. I am starting to wonder if ghostly prison should just go MD instead of myr enforcer. I am not sure if anyone else is testing somber hoverguard but he really is a bomb that usually drops for one, he also carries plating like a champ plus he is actually big enough to end games because of his size. Removing Disciple and vial is definitly taking this deck away from being normal affinity. Hanna's Custody seems like a perfect inclusion for the board.

anyways I figure I would post the must includes for the deck.

4 Wasteland
4 Sphere of Resistance
4 Thorn of Amethyst
4 Winter Orb
4 Frogmite
4 Cranial Plating

Without the above cards the deck would fall flat.

While nexus seems really good in the deck i tested it and found it to be only ok.
