Frequently asked
What is Union Arena?
Union Arena is a two-player trading card game by Bandai built around anime titles. Every booster covers one series (Bleach, Chainsaw Man, Jujutsu Kaisen, Re:Zero, Evangelion and many more), and each deck is built from a single title. The English version is supported by Bandai's official Championship circuit with store events and Regionals.
What are the Union Arena deck building rules?
A deck is exactly 50 cards, all from one title: the three letters after the slash in the card number (for UE24BT/REZ-1-001 that's REZ). You can run up to 4 copies of the same card number, and at most 4 cards each with the Special, Color and Final triggers. The 3 Action Point (AP) cards sit outside the 50-card deck. The deck builder checks all of this for you.
What do Energy, AP and BP mean on a card?
Energy is the energy a card needs on your energy line before you can play it, and the colored icons show which color. AP is the Action Point cost to play it. BP (Battle Points) is a character's strength in battle. Many characters also generate energy once they're on your energy line, shown as Generates on this site.
What are triggers?
Some cards have a trigger effect that activates when the card is revealed from your Life Area. The trigger types are Get, Draw, Active, Raid, Special, Color and Final. Only Special, Color and Final are limited to 4 cards each per deck.
Which Union Arena starter deck should a beginner buy?
Start with the starter deck for a title you like, ideally one that also shows up in tournament results, so upgrades are easy to find. Every English starter is a ready-to-play 50-card deck with 3 Action Point cards and a playsheet, for about $11.99.
Can I play Union Arena online?
Bandai has no official online client for playing Union Arena. Online play runs on free, fan-made browser simulators, and Bandai's official app is for learning the rules, not for matches. Sanctioned play happens at local game stores and Championship Regionals.
What's the latest Union Arena set?
The newest booster in the database is UE24BT: Re:ZERO -Starting Life in Another World- (UE24BT). Upcoming sets appear on the release timeline above as soon as TCGplayer lists them.
Where do the decklists come from?
Tournament results are collected daily from English-language events: store tournaments, online weeklies and Regional top cuts. 1518 decklists are on the decklists page, each with the full 50-card list and a link to open it in the deck builder.
Where can I buy Union Arena singles?
TCGplayer carries the full English Union Arena catalog, from every booster to promos. Sealed product (boosters, starter decks) is sold at local game stores carrying Bandai titles. Card pages on this site show daily TCGplayer prices, and the deck builder can send a whole deck to your cart.
