Collectible Card Game Headquarters

I made a cube fast and dirty for practicing Ultimate Masters. It's composed of old copies of the cards. If anyone can fix the rarities to show up properly, that would be great. I approximated rarities by setting 1 copy for rare and mythic, two for uncommon, four for commons, and set it yu singleton mode. The problem with doing it properly is that a lot of rarities don't line up with the originals. Drop the draft in forge-gui-desktop.../res/draft and the deck in res/cube. Let me know if I did something wrong or need to explain better. This is my first time putting my work on this site.
