This is a set cube that aims to copy the official, MTGO-only release of Tempest: Remastered, that took cards from throughout the whole Tempest block and shifted their rarities around to create a new set that reflected the structure of any current-day magic set - 101 commons, 80 uncommons, 53 rares, and 15 mythics.

For the physical copy of this cube I have included 6x each common, 3x each uncommon, 2x each rare, and 1x each mythic in the set. The commons are all shuffled together, as are the uncommons, and the rares and mythics are shuffled together as well. Then, 10x random commons, 3x random uncommons, and 1x random rare or mythic are selected to make up each pack.

You can read more about Tempest: Remastered in the official announcement article, which can be found here:
