Khans of Tarkir set cube for a semi-simulation for 360 card draft.

Minor changes to land base to ensure each pack has 1 rare or mythic, 3 uncommons, 10 commons, and 1 land card in each pack. All non-land uncommons, rares (except fetch-lands) and mythics (except ugin's nexus) are actually stored separately, shuffled separately, and then added to the cube packs in their respective slots just prior to play to simulate drawing randomly from packs/boxes/cases. Therefore, rares in the cube list are representative, not definitive. All non-land uncommons but 2 are included, and all non-land commons are present at least twice, and only 59 commons have third copies. This gives a 10/3/1/land ratio per pack, and 3/2/1/1 for the cube. Singleton is only broken for the commons and uncommons, and with a rotating pool of rares/mythics, it can feel more complex than a normal 360.

Please draft and/or send feedback and let me know what you think!
