This "cube" is meant to be played the same way as the jumpstart products. Two packs are picked at random by each player and shuffled together to make a deck. I have kept the theme names from the jumpstart products, but the packs have been changed by quite a bit. I have tried to keep the number of rares/mythics in each back to 2 or 3. The themes are:

• Angels - tribal with a stax subtheme
• Basri - a combination of tokens and counters
• Blink - gain advantage from enter the battlefield triggers and then trigger them again
• Chandra - spells and noncombat damage
• Constellation - bestow blessing across the battlefield
• Cycling - gain advantage through.. discard?
• Demons - tribal with a sacrifice subtheme
• Detective - solve the mystery of how to draw cards
• Devilish - tribal with direct damage on death
• Dinosaurs - tribal with a power subtheme
• Discarding - relieve your opponents of their hands
• Doctor - keep your life total high
