I love mill decks, so when Phenax, God of Deception was spoiled in Born of the Gods, I immediately set about building a UB mill deck around Phenax.

The deck is a work in progress, but the initial results seem promising, at least for casual play. The plan for the deck is to use Frostburn Weird, Wall of Frost, Dissolve, and Hero's Downfall/Ultimate Price to survive until turn 4-6. Triton Tactics can be used offensively (to mill with Phenax), or defensively to survive the early-mid game. Jace, Memory Adept and Liliana of the Dark Realms (another personal favorite that sadly does not see a lot of play) both help with card advantage (though in different ways).

The deck can win by milling alone, or by turning milling into life loss/beatdown with Consuming Aberration and Duskmantle Guildmage, respectively.
