With this cube, I'm trying to make a fun/draftable set out of the Invasion block (INV, PSF, APC), with reatail-like boosters type of Draft, with a land slot, 10 Commons, 3 Uncommons and 1 Rare.
The commons are supposed to be doubled, so the table can draft 240 commons, every one in the set, and 72 uncommons. That way, it's an easy cube to assemble and can be well drafted on a 8 person table.
