In two separate posts today, Wizards of the Coast announced the next Masters set in Double Masters. The set is slated to be released August 7th, 2020 (and will hit Magic Online on August 6th, with boosters available there for $6.99). The 332 card set will be made up of reprints and each booster will have two Rares or two Mythic Rares, as well as two Foils (yes, this means there is a chance at four rares per pack). Double Masters will not feature Collector Boosters but rather will have something called VIP Edition – details to be coming soon. Each box will come with not one but, you guessed it, two extended art Box Toppers from a list of 40 cards.
Update: Omitted from the earlier post, while Double Masters is a reprint set, it will not feature the promised fetchland reprint in 2020. Additionally, when Double Masters is drafted players will take two cards with their first pick in each pack (Pack One, Pick One, Pack Two, Pick One, and Pack Three, Pick One).
