After cutting down to 40 cards this deck went 2-2 in trad draft - I made a blue with white splash high alert/mill deck and an azorius anti-aggro that I could sideboard into if I was quick enough (I would add forbidding spirits and ministrant).

Here's how I split the draft into different card packages to help me choose a deck strategy:
