The opening of the Magic: the Gathering Set Booster packs on live sell is still ongoing for me despite our Standard card pool in almost 100% complete. This might be on testing my luck despite some of these other cards being already available and on hand. Maybe with the chance of selling them to the other players in the community? Or just to collect the extras in preparation for the next Standard rotation? Or maybe it is just The List cards in these set booster packs that I am trying to hit?
