This is a non-powered 450 cards cube.
I decide to broke the singleton rule, but only with a very selected few cards, to achieve speciffic goals in design:
3 Brainstorm
3 Wasteland
3 Gravecrawler
2 Carrion feeder
2 Blood artist
2 full sets of fetchlands
_________
=32 non-singleton cards (6%)
___________
Players are allowed to pick 4 extra "utility land" from "Pif cube utility land draft" (Jason Waddel's idea)
