Artifact Chaos Refined
Alternate title: Mystery Booster - Artifacts

This is a curated chaos format about artifacts (and some other minor themes from the artifact sets, like infect/toxic, equipment and proliferate). The cards are set to what I call their "vacuum rarity", the perfect rarity for them to appear in in a chaos format.

Packs have 16 cards, including a land slot with some dual land cycles, artifact lands and spheres.

Basically, this is meant to be the ultimate Artifact Chaos format which you can draft dozens of times before it starts feeling repetitive.
