A pauper cube, originally based on one of Usman Jamil's pauper 360 cubes, but heavily modified. It ballooned to 450 and then was in the process of being downsided to 360 when I disassembled it in favor of Ryan Overturf's Peasant Twobert (a 180 card two person cube) as I only play mtg with my wife these days.
