A set cube designed to emulate the Unstable draft environment- with a twist!

Designed to be divided into booster packs according to rarity, to simulate an Unstable draft as closely as possible. Breakdown is as follows:
-8x Commons
-3x Uncommons
-1x Rare
-2x Contraptions (Any rarity)
In addition, I include 1-2 cards in each pack from a curated bonus list:

The number included depends upon how faithful you want the draft to be. :)

For the uncommon and rare variant cards, the cube includes marker cards that are exchanged for one of the appropriate variants (chosen at random) when the pack is opened. These cards are: Knight of the Kitchen Sink, Very Cryptic Command, Sly Spy, Garbage Elemental, Ineffable Blessing, and Everythingamajig.

Secret Base is represented with a voucher card. At the end of the draft, each player who drafted any of these cards may exchange them for a Secret Base variant of their choice.
