This is the first Union Arena TCG title to release both in Japanese and English at the same time. The set will feature 30 types of cards with brand-new illustrations for heroes like S-Ranked Genos, King, Tatsumaki, and of course, Saitama. There will also be SR★★ card types (chase cards) included in the set with foiling and signatures of the original cast printed on them.
The set rarity breakdown is as follows: 35 commons, 35 uncommons, 21 rares, 12 super rares, and 6 action point cards, for a total of 103 cards plus 6AP card types. Booster packs come with 12 cards in displays of 16 packs. There will also be starter decks that come as 50-card ready-to-play decks.
