This cube can support a six-person pod using 4x15 card packs as their pools. The Un-cube is a mix of all five un-sets. However, it is heavily based in Unstable as this is the more complete draft format.
While the archetypes are not nearly as even as in other cube environments, the draft experience is still very strong.
Remember that there are 48 Contraptions in this cube along with 24 Attractions, which means the body of the cube is not 360 cards. This is fine as I seed 2 Contraptions and 1 Attraction in every 15 card pack, and each player gets 4 packs instead of 3.
I have included tap lands to smooth mana-fixing, and all the basics are from different sets.
