Atraxa, Grand Unifier

How it plays & wins

This is a five-color turbo deck led by Atraxa, Grand Unifier, though the commander is more of a late-game option than the plan. Mana rocks, mana dorks, Dark Ritual and Chrome Mox get things moving fast, while Demonic Tutor, Vampiric Tutor, Enlightened Tutor, Worldly Tutor and Chord of Calling find the right pieces. It plays a lot of interaction, including Force of Will, Force of Negation, Pact of Negation, Swan Song and Flusterstorm. Silence and Grand Abolisher help push the win through, and Rhystic Study and Smothering Tithe provide value if the game goes long.

The most likely win is a tutor-fueled Thassa's Oracle finish, using Demonic Consultation or Tainted Pact to empty the library while holding counter-magic as backup. Food Chain is a second route with creatures like Misthollow Griffin, but the list doesn't make the exact finish clear to me.
