Pioneer Masters is an upcoming Arena-exclusive reprint set meant to make the Pioneer format playable on Arena. Its release date has been pushed back many times, but was last stated to be by the end of 2024. See this wiki article or this recent reddit thread for context.

When the set releases, all options in this market referring to dates in the future resolve YES. When a date arrives without the set releasing, the option for that date resolves NO.

Edge case clarifications:

• The set's release is defined as the moment the servers come back up after the patch that makes packs of the set purchasable.

• This market uses US Eastern Time to define dates.

• If the set has a different name than "Pioneer Masters" but is clearly still the same concept, it still counts.
