I mixed six packs of RTR from the Rakdos Guild box, six packs of GTC from a road trip, and twelve DGM packs. Thats 6-6-12, for 24 packs of the RTR block. I made some really great pulls, as I always do when I buy unperturbed sealed product. Here are the white cards and the two non-mana fixing artifacts.
At 17 creatures there are barely enough to build a 40-card deck. I am planning to build guild and shard Standard and, if possible, Commander decks out of this mini-cube. Mono white is not happening in this selection. Because of the guild keywords these cards are going in guild directions, not in the traditional "is in white" direction.
