Very basic 4-3-2-1 ratio set cube for Unstable. The only exception is a total of 5 Secret Bases to have 1 of each.

Pack layout

• 8 commons
• 3 uncommons
• 1 rare/mythic
• 2 contraptions

Variants
Unstable has a handful of mechanically-different card variants, such as Everythingamajig A and Everythingamajig B. For these, I'm picking my favorite from rares and favorite 2 from uncommons. Common variants are just art/flavor text.

Steamflogger Boss
Steamflogger Boss is included as a normal red rare.

Spike, Tournament Grinder
I will have a curated list of cards Spike can fetch from among banned cards. This list includes:
Balance, Lingering Souls, Fall from Favor, Hurkyl's Recall, Demonic Tutor, Braids, Cabal Minion, Lightning Bolt, Faithless Looting, Regrowth, Birthing Pod, Sojourner's Companion, Cranial Plating, Smuggler's Copter, and Arcbound Ravager.
Players may additionally fetch any banned cards they provide.

Exclusions

• Better Than One - Better Than One makes sense when at a full store/convention/event Unstable draft, where several people are hanging around to play silver-border, or you may find people between rounds to pull in. However, in cube the player population is much smaller and so you may not find people who have already finished their game(s) to join yours, and trying to coerce any outside person(s) nearby will be at best awkward. It's not worth the trouble.
