Pioneer Masters is a digital-only reprint set that was once was planned to be be released on Magic Arena. It would be combining cards from all the sets legal in Pioneer, pulling them together into a single set for both Limited and Constructed play.[1]


The set was originally planned for release at the end of 2020, but was pushed back to 2021 for more playtesting.[2] In July 2021, it was put on hold.[3]

It was stated that Wizards of the Coast's schedule didn't have room to focus on growing a unique identity for the Historic format while fully supporting Pioneer at the same time. Some steps toward Pioneer were expected to come as part of Historic's growth, but they paused work toward Pioneer Masters sets for the time being.[3]

In August 2021, the release of Jumpstart: Historic Horizons included a selection of cards with digital only mechanics. This addition to the historic format, alongside the December 2021 release of Alchemy: Innistrad which paired Historic with it in terms of card changes, meant MTG Arena lost its only "true to tabletop" non-rotating format. As the introduction of Pioneer also had been put on hold, the negative feedback forced Wizards of the Coast to quickly announce that they would be searching for an alternative.[4] Although people asked for the return of Pioneer or Pioneer light, Wizards seemed to search for another format. This made the eventual release of Pioneer Masters even more unlikely.

However, when Explorer was introduced as a format in April 2022, this turned out to be exactly what the people had been asking for: a Constructed, non-rotating, "true-to-tabletop" format using all the Pioneer-legal cards available on MTG Arena, with a path towards becoming Pioneer.[5] On Weekly MTG it was stated that Pioneer Masters was still a possibility but wasn't on the schedule for the immediate future. They also said that priorities could shift and that it was more likely to happen if Explorer would take off.[6]
