Unstable

Unstable

Unstable is a booster-based card set for Magic: The Gathering that can not be used in legal Magic tournaments. It was released on December 8, 2017 as a standalone set. This is the third of the silver-bordered Un-sets and is designed to be drafted.

Unstable contains "216-ish" cards (5 basic land, 75 common, 75 uncommon, 46 rare, and 15 mythic rare) and 20 foil tokens, and includes randomly inserted premium versions of all cards. The set explores new areas of Magic game design and continues the tradition of bending the conventional rules of the game in a fun and whimsical way. Unstable was designed to both be drafted alone and be mixed with other sets: according to Mark Rosewater, however, the best experience is probably when it's drafted alone. The expansion symbol is a wrench with an acorn-shaped hole.
