(More information regarding card distribution can be found in Card Rarity)
There are three types of special rarity that the deck building algorithm uses, according to the Master Vault:
- FIXED cards always appear with one (or more) other cards. As the deck building algorithm assigns one card it also assigns the cards that are FIXED with it. For example, with the Four Horsemen, when the algorithm assigns Horseman of Pestilence to a deck, it also assigns it Horseman of War, Horseman of Death, and Horseman of Famine.
- As of the release of Age of Ascension, Variant cards are assigned to a deck and then modified based on other contents of the deck. For example, the algorithm decides to assign an Ambassador to a deck, and then based on the non-Sanctum houses in the deck, an appropriate Ambassador is assigned. In Call of the Archons, the Masters were the only variant, and they were inserted slightly differently; Master of 1 was inserted into the deck, and then based on the contents of the deck, it was either left as Master of 1 or changed to Master of 2 or Master of 3.
- As of the release of Mass Mutation, the vault returned a rarity actually called "Special". The only card with this rarity so far is Dark Æmber Vault.
