The SLX program is the name for a series of rebranded versions of mechanically unique Universes Beyond cards.[1] Initially these were all rebranded as part of the Magic multiverse, and the term Universes Within was coined for the program by Scryfall. The term was temporally adopted by Wizards of the Coast internally, but never was an official product name.[2][3] When they broadened their scope, the "SLX program" name was adopted.[1] Cards printed under this program all have the set code "SLX".

Description[]

In 2021, Wizards of the Coast pledged to create and print in-multiverse versions of mechanically unique non-canon Secret Lair cards, approximately six months after their original release of the Secret Lair.[4] These would become available as part of The List, and were said to be findable in Set Boosters for as long as players still were interested in opening them.

The non-canon cards and the rebranded cards are considered equivalent game pieces, meaning you can only play up to four copies total of the rebranded version and Universes Beyond version combined in your deck. The Information below the text box has the special SLX set code and the SLD card number that it equals.[5][6] All rebranded cards have the same rarity as the original. If a Universes Beyond card with an IP-specific creature type (e.g. astartes) would be rebranded, it would receive a brand new creature type in the rebranded version. The <IP name> and <unique new creature type> would be one-for-one in the rules much like the names of the Godzilla skinned cards.[7]

At their introduction, one in eight Set Boosters contained one of these cards, while another one in eight set boosters would contain a different card from the List.[8] According to Mark Heggen, R&D wanted the in-world equivalents those to be around and people able to get their hands on them.[9] They were not meant to be the ‘chase objects’. After 10 years, they wanted the "other-IP" ones "to be the cool ones that had a little bit more cachet and would be a bit more interesting to see". The in-world equivalents would be the ones that were there for people who were just looking for the gameplay.[9]

Wizards of the Coast did only commit to do Universes Within versions of Secret Lairs. Larger UB sets like Warhammer 40K, Lord of the Rings and Doctor Who wouldn't receive 1:1 Universe Within versions, but R&D reserved the right to make them for individual cards if the need arose.[10][11] According to Mark Rosewater, the biggest problem, from a business standpoint, with making a Universes Within card for every Universes Beyond card was that there wasn’t a large enough audience to offset the huge cost of such an undertaking.[12]

In November 2024, Rosewater went back on the promise to always create Universes Within versions of mechanically unique Secret Lair cards. He explained that since The List and Set Boosters had been phased out, Wizards was in a conundrum. Although they still wanted to create non-Secret Lair versions, they could no longer guarantee that these would always be different from what the Secret Lair had offered. They might keep the same name, and represent the same character/object/place - hence, it wouldn't always be a “Universe Within” version.[13] This came true with the release of the Spring Flourishes promo cards in January 2025, which were still part of the D&D universe.[14] In addition, it was announced that upcoming mechanically unique Secret Lair cards would become available for purchase in local WPN stores.[1] The selected Secret Lair Drops available for WPN stores to sell will be identical to the non-foil Drops available on the Secret Lair website.[15] This implies that no more future Secret Lairs will be rebranded.
