It's practically impossible to predict why what might appeal to to who, so a broad selection of cards was the best strategy here
Speaking of our curve topper, its obviously Avacyn, Angel of Hope
Due to all this flexibility, I wont be surprised if this is the most-played Commander in the set overall when the dust settles
