1 Traditional foil full-art basic land 1 Traditional foil showcase or borderless uncommon Can be one of: 8 Showcase Legends of Ixalan cards (55%) 6 Borderless Dinosaur cards (41%) 5 Borderless Special Guests cards (3%) 1 Traditional foil rare or mythic rare Can be one of: 64 Rares (85.3%) 22 Mythic rares (14.7%) 1 Non-foil extended-art rare or mythic rare Can be one of: 38 Rares (97.4%) 2 Mythic rares (2.6%) 1 Non-foil or traditional foil single-faced extended-art Commander rare or mythic rare 12.5% of Collector Boosters contain a traditional foil card in this slotthis includes new Commander cards in extended art, including the new Commander content found in Set Boosters, the 2 mythic rares in each Commander deck, and the 1 mythic rare in each commander deck in an alternate style
