This deck is a combination of counterspells and mill cards. Mill or exile the opponent's library, and use cards such as Nightveil Specter and Ashiok, Nightmare Weaver to play their goodies. Either you deck them or crush them with stompy creature from their deck or an overpowered Consuming Aberration.

I'm thinking about adding Triton Tactics to help with the milling, but can't decide what cards to remove. Any thoughts?
