Restrictions on Card Usage
In UNION ARENA, a deck may have up to 4 cards of the same card number. However, in official and sanctioned tournaments, the number of some cards that can be included in the deck will be restricted.
- *Cards with the same card number but with different illustrations are also considered the same cards.
Selection and Announcement, and Enforcement.
- ・We will closely monitor the win-rates, tournament results, and usage of certain decks to consider enforcing restrictions if certain decks deviate from our game’s objective.
- ・Please note that depending on the environment of the game, the status of [Restricted Cards] may change.
- ・We will continue to announce considerations for these restrictions through official broadcasts after major events and tournaments, Producer’s Letters, and the official SNS. When this page is updated, there will be a post on the official SNS as well.
- ・We plan to review the restricted card list once every 6 months and will only lift restrictions on cards if we do not observe a significant bias in the outcome of the events.

THE IDOLM@STER SHINY COLORS
IMS-3-040
Black Comet
In the deck commonly known as the “Purple CoMETIK Deck” from THE IDOLM@STER SHINY COLORS, this card can be placed into the Outside Area through an effect, allowing the player to draw cards and increase their hand size from the early stages of the game without paying AP.
This gives the deck a high level of consistency in accessing the cards needed for different situations, resulting in an advantageous position against a wide range of decks.
Both the usage rate and win rate of decks utilizing this card have exceeded the established thresholds in tournament play.
As this situation is inconsistent with UNION ARENA’s core policy of providing an environment where players can enjoy a wide variety of decks and titles, IMS-3-040 Kuroiro Suisei will be designated as a Restricted Card, with a maximum of 1 copy permitted per deck.
Mushoku Tensei: Jobless Reincarnation
MST-1-051
Roxy
Green decks from Mushoku Tensei: Jobless Reincarnation can activate powerful effects by having Character cards that serve as attackers, as well as multiple Field cards, in the Outside Area.
When this card is played, its effect allows the player to place a desired card into the Outside Area. In addition, it generates 2 Activation Energy and can also serve as the base card for Raid, allowing a single card to fulfill multiple roles.
This greatly improves the deck’s consistency and has resulted in an advantageous position against a wide range of decks.
Both the usage rate and win rate of decks utilizing this card have exceeded the established thresholds in tournament play.
As this situation is inconsistent with UNION ARENA’s core policy of providing an environment where players can enjoy a wide variety of decks and titles, MST-1-051 Roxy will be designated as a Restricted Card, with a maximum of 1 copy permitted per deck.
Restricted Cards (2)
Only 2 cards can be included in the deck.
Evangelion: New Theatrical Edition
EVA-1-105
Evangelion Unit-00
In the deck commonly known as the “Red Pseudo-Evolution Deck” from EVANGELION, when this card leaves the field, its effect allows the player to draw 2 cards and then place 1 card from their hand into the Outside Area to play a Rei Ayanami card with Required Energy 1 or less.
Depending on the situation, this can be used either to increase available energy or to place a desired card into the Outside Area.
In addition, its ability to block twice can prevent opposing attacks during the early stages of the game. These effects can then lead into multiple attacks using EVA-1-079 Evangelion Unit-01 Pseudo-Evolution, resulting in an advantageous position against a wide range of decks.
Both the usage rate and win rate of decks utilizing this card have exceeded the established thresholds in tournament play.
As this situation is inconsistent with UNION ARENA’s core policy of providing an environment where players can enjoy a wide variety of decks and titles, EVA-1-105 Evangelion Unit-00 will be designated as a Restricted Card, with a maximum of 2 copies permitted per deck.
