Updated: 5/28/2013This is the new standard sideboard using data collected from mtgstats.com (http://mtgstats.com)
I sifted through everything to find the 5 more relevant archtypes, and the cards that appear most often in their sideboard. This is raw Magic Online data derived from the Wizards website and filtered through MTGstats. Every day, the latest events are analyzed and decks are automatically assigned to their archetypes. Every month i'll be updating the standard sideboard.
