In Dominaria United, we return to the Legendary world of nostalgic heroes and villians and join "The Coalition" on their newest challenge.
Draft, Set, and Collector Boosters all make their return in Dominaria United alongside new Jumpstart Boosters! Jumpstart Boosters are modeled after booster packs from the original Jumpstart set and allow players to battle with only a couple packs.
To help celebrate this Legendary set, Dominaria United Collector Boosters have a chance to include a card from the 1994 set Legends. For more details, read this article from Wizards of the Coast. In addition, Dominaria United will include reimagined Legendary creatures (and planeswalker) from Legends as traditional foil Box Toppers. These 20 brand-new cards are legal for Commander and Eternal formats only.
