Having been a fan of the B/W or Orzhov deck archetype, I am happy to present to you another version of the deck which is currently built for Shadows over Innistrad Standard. The midrange approach looks to be efficient as the access to the late game with powerful cards such as Gideon and Sorin and gets you ahead and overwhelm your opponents.

Here is a build that finished Top 8 from SCG Open Baltimore and was piloted by Blake Conti.
