I find cube design overwhelming. The thought of having to gather a list of 360 cards together to create a fun drafting environment seems beyond my abilities. Whenever I begin creating a list, I quickly realize I’m in over my head, and that’s before I even begin to consider the financial cost of gathering all the cards together. Once I start adding up what’s it going to cost to compete the cube I give up. For a long time it seemed like I was going to be stuck building block cube based of other people’s list with a few tweaks here and there. Fortunately, WotC created Mystery Boosters.
