This top 10 submission is to check if Upheaval is worth the trouble to write small expansion sets to. The most prominent chart-toppers will have deck-building combo cards and answer cards made for them, and the most prominent worst cards will have some way to make them better in the 'red set', Pandemonium.
After the red set, the blue set will follow, named after some blue card.
