Union Arena My Hero Academia New Card Selection lands December 11
Bandai's 12-card My Hero Academia New Card Selection for Union Arena boosts the Green, Red, Purple, and Yellow decks, with 11 new cards, one AP card, and a mounting board.
Bandai will release the My Hero Academia New Card Selection for Union Arena on December 11, 2026. It is a 12-card upgrade set aimed at four existing decks of the My Hero Academia line: Green, Red, Purple, and Yellow.
What is in the set
The product holds 12 cards in total. Eleven are new cards designed to power up a deck a player already owns, and the twelfth is an Action Point (AP) card. A special mounting board comes with the cards.
Every character card in the set carries brand-new text. Bandai says that pairing them with existing cards produces synergistic effects.
The AP card has a special illustration commemorating the 10th anniversary of the anime.
Release date and region
The release date is December 11, 2026. No sales region has been announced, and neither have sales channels. It is also not announced whether the set will be sold in several languages.
Bandai notes that the illustrations and product details shown may differ somewhat from the final product.
Where it sits on the Union Arena calendar
December 11 is a busy date for the game. TCGKing has already covered the Umamusume: Pretty Derby Starter Deck and the Uma Musume booster pack, both set for the same day.
Earlier on the calendar, the D.Gray-man booster UA58BT and Monogatari Vol.2 are both listed for November 27, 2026.
What is still unknown
Several basics are missing:
- The price is not announced yet.
- The card names and the full card list are not announced yet.
- No product code has been announced.
- Sales regions, sales channels, and language versions are not announced yet.
The mounting board's design is also not described beyond its being special.
What it means for players
- Players of the Green, Red, Purple, or Yellow My Hero Academia decks are the target audience; the set is built to strengthen those four.
- Because all character cards in the set have new text, the card list will matter once it is published, particularly for how they combine with cards already in a deck.
- Collectors should note the AP card with the 10th anniversary anime illustration and the included mounting board.
- Players should wait for confirmation of regions and languages, as none has been announced.
