New Title Announcement

We are excited to announce the upcoming addition of “That Time I Got Reincarnated as a Slime”! This title will be released as a special booster with a larger card variety than usual. It will introduce all four colors at once, allowing for a wide range of deck-building possibilities. The set is designed to fully capture the world and themes of the series—please look forward to more details which are coming soon!

About Card Restrictions

To ensure that all UNION ARENA players can enjoy a healthy environment with a wide variety of decks, we review official and authorized tournament results and apply restrictions on certain cards when appropriate.
For the English version, we conduct ongoing testing and make adjustments whenever necessary so that players can enjoy the fairest gameplay environment possible. In addition, we will continue to review the current state of the game and lift restrictions when the environment allows.
After carefully analyzing tournament results and usage trends from October and November, we have decided to lift the following restriction:

Based on the current gameplay environment, we are lifting the combination restriction for JUJUTSU KAISEN.
Since the English release of JUJUTSU KAISEN, this specific card combination has been restricted for a long time, but we are now pleased to allow players to use these cards freely once again. We hope you enjoy building and playing Blue Sukuna decks in this new environment.

In addition, we have an extra update to share.
The card “BLC-1-051 Rukia Kuchiki”, which could not previously be included in the BLEACH: Thousand-Year Blood War Booster Pack, will be distributed as a Participation Prize card in upcoming Store Tournaments.
We sincerely apologize for the long wait this has caused for many BLEACH fans, and we hope you will take this opportunity to join the events and pick up the card.
Please look forward to updates on the official website for more details.
Thank you for your continued understanding and support.
