CardSpicy builds card protection products and runs this collector’s index. We cover Pokémon, One Piece, Gundam, Dragon Ball, Naruto, Yu-Gi-Oh!, Digimon and Riftbound, plus our newer sections on Magic: The Gathering, Disney Lorcana, Star Wars: Unlimited, Flesh and Blood and UNION ARENA — every card game we index in full, with the sleeves and rigid holders that fit them. We sell PSA 10 only, because that is the grade the market actually trades.
CardSpicy indexes card games with an emphasis on the Chinese-language editions, and UNION ARENA is the line on this site that is built entirely out of other properties. It is a crossover card game from Bandai in which every product is built on a licensed anime or game series, and the series share a card frame but not a card pool.
This page is the index for everything CardSpicy publishes about it: the four card types, the rarity labels and the variant printings, the source-material rule that decides what may go in a deck, and the product lines that carry the game.

Card types and rarities
UNION ARENA runs on four card types — characters, field cards, events and Action Point cards — and on a rarity set the publisher lists inside every booster product page. The publisher also prints variants on top of those rarities, including parallel rares and, on some products, foil-stamped signature cards.
- UNION ARENA card types and rarities — what each card type does, the rarity labels the publisher prints, and the variant printings that sit above them.
Products and releases
The product line is unusually wide for a game this young, because each licensed series arrives with its own booster pack and its own starter deck. Alongside those the publisher runs four smaller categories: Precious Booster Packs, Advanced Decks, New Card Selection products and Playmat and Action Point card sets.
- UNION ARENA products and releases — the product categories the publisher names, and how the release programme is organised around licensed series rather than around numbered sets.
The dated release schedule is covered in its own page on this site, written from the publisher’s own calendar.

Where to start
The entry point here is a rule rather than a product, and it is the one thing that distinguishes this game from most card games: a deck may only contain cards that share a single source material code. That is why the first decision in UNION ARENA is which series to build, not which cards to chase.
- How to start a UNION ARENA collection — the deck construction rules, the fifty-card deck and three Action Point cards, and what each product line actually supplies.
Where this section sits
UNION ARENA is one of the card games given their own material on CardSpicy. The lines that do not yet have a full section are collected on Other card games. Every page the site publishes, grouped by game and then by topic, is on All articles, and the sleeves, holders and storage that go around any of these cards start at Card accessories.
Frequently asked questions
Does CardSpicy index UNION ARENA cards?
It indexes the game rather than a card list. CardSpicy publishes guides to the card types, the rarities, the deck construction rules and the product lines; it does not run a page-per-card database for UNION ARENA.
Who publishes UNION ARENA?
Bandai. It is a crossover trading card game in which each product is built on a licensed anime or game series, and the series share a card frame but not a card pool.
How many card types does UNION ARENA have?
Four: character cards, field cards, event cards and Action Point cards. A deck is fifty character, field and event cards plus three Action Point cards.
Can I mix series in one UNION ARENA deck?
No. Every card in a deck must share the same source material code, which is the three-letter code in the card’s number. Cards from different series cannot be mixed in the same deck.
What is the newest UNION ARENA product line?
The Advanced Deck line, which began with a BLEACH: Thousand-Year Blood War deck released on 11 September 2026. Before that the line ran on booster packs, starter decks and the smaller special categories.
