Modern Horizons is a Magic Booster Set released June 14th, 2019. All orders will be shipped for arrival as soon as possible. We anticipate this will be allowed by Wizards of the Coast from the 8th June.
The set introduces new cards directly in to Modern, because of this the power levels are capable of bypassing Standard. Each booster pack contains a full-art snow land, 15 cards and 1 rare or mythic rare.
Each Booster Box contains 36 packs of Modern Horizons.
The set features a number of reprints of cards previously only legal in Legacy, as well as rigorously tested powerful cards for the Modern format. We think a lot of them look GREAT for Commander too.
