Japanese card shop Duel Guard leaked the release date and names for three new Starter Decks launching on November 27th: Giga Green, Venom Violet, and Mugen Black. Each deck will retail for 500 yen before tax. Each deck will contain 16 kinds of cards, similar to the first three: 7 Commons, 5 Uncommons, 3 Rares, and 1 Super Rare.
Duel Guard is an officially licensed shop in Chuuoumachi, Niigata prefecture. They leaked the news in order to begin taking preorders at their store. Their post was corroborated by Card Land Akihabara, which is also taking preorders for the decks. Similar to the situation with Booster Set 3—which is currently up for preorder on Amazon Japan—Bandai has not officially confirmed or denied the existence of the Starter Decks. The timing of the decks would place them roughly a month after UNION IMPACT is supposed to launch in Japan.
Japanese fans are treating the leak as real, and speculating based on the names that the cover cards will be new prints of Herakle Kabuterimon, Venom Vamdemon, and Mugendramon.
