The Mythical & Legendary Dream Shine Collection is the fifth Concept Pack of the Japanese XY Era overall, and third of the XY BREAK Era. The set consists of 38 cards, all of which are Holographic and have no printed rarities. As with the majority of Concept Packs, each pack contains 4 cards instead of the usual 5. The set features a large selection of Full Art cards, comprising those initially available in the Mythical Collections outside Japan as part of the ongoing Pokémon 20th Anniversary merchandise campaign, in addition to the last Generation VI Mythical Pokémon Volcanion, and the newly-revealed Generation VII Mythical Pokémon Magearna. The set also includes a number of cards with previously English-exclusive artwork, originally available in various TCG related products released outside Japan.
