Features of UNION ARENA Precious Booster Pack THE IDOLM@STER Shiny Colors [PCO1BT]

The UNION ARENA Precious Booster Pack THE IDOLM@STER Shiny Colors [PCO1BT] is a special booster pack focused on collections, allowing you to enjoy Shiny Colors characters in high-quality, precious specifications.

Basic product information and specifications

PC01BT is a special edition of the UNION ARENA series, equivalent to a "Precious Booster Pack," and will be released on January 16, 2026.

• Product Name : UNION ARENA Precious Booster Pack THE IDOLM@STER Shiny Colors [PC01BT]

• 1 pack : 4 cards

• 1 BOX : Contains 10 packs (40 cards total)

• Price : 495 yen per pack (tax included) / Reference price for one box: approximately 4,950 yen (tax included)

• Cards included : 50 types in total + 8 types of AP (Action Points)

The most distinctive feature of the Precious Booster is that "all cards are Precious Edition," meaning that all cards, from common to high rarity, have a luxurious finish with foil stamping and special processing.

Three major features of the PC01BT

1. All cards are made of precious material.

Unlike regular boosters, PC01BT consists entirely of Precious cards .

• Common and uncommon rarity cards are also available in foil-stamped, high-color precious finishes.

• There's less chance of disappointment, and the satisfaction upon opening the package is high.

• The cards themselves have very high "aesthetic value," and the collector experience is highly valued.

This specification allows Shanimas producers (fans) to enjoy the beautiful illustrations of their favorite idols on cards, and makes it easier for UNION ARENA players to obtain high-quality cards.

2. A composition of 50 carefully selected types + 8 AP types.

The set includes 50 different cards plus 8 AP cards , a more carefully selected variety compared to regular booster packs.

• The number of characters has been streamlined, and the design of each unit stands out.

• The costumes and facial expressions are varied and recreate the world of Shiny Colors.

• While the number of cards per box (40) is modest, the high density of the precious cards emphasizes the quality of the unboxing experience.

This configuration is positioned as a special edition that "makes buying a box worthwhile," and is designed with both collectibility and practicality in mind.

3. A dual structure of collectibility and practicality

PC01BT is not just a reprint pack; it's a "dual-structure" product that meets the needs of both collectors and players .

• Collector's perspective : The cards are primarily valued for their beautiful illustrations and limited-edition finishes, which contribute to their inherent value.

• Player's perspective : Can be used to strengthen existing Shanimas decks, secure AP, and reinforce key cards.

Therefore, for Shanimas producers, this pack is a commemorative set for obtaining their favorite character's Precious Card, and for UNION ARENA players, it's a suitable pack for building a foundation for their decks.

Highlights of popular and rare cards

The appeal of PC01BT lies in its Precious Cards featuring popular characters and powerful cards that are effective in actual gameplay.

① Popular cards sought after by collectors

As expected from a Precious Booster, cards with beautiful illustrations and limited-edition finishes are proving popular.

• Special illustrations of major units (e.g., Luminous, ALSTROEMERIA, Straylight, etc.)

• Foil-stamped special cards of popular idols (e.g., Osaki Amana, Osaki Amana, Amagase Fuyumi, etc.)

• Signature-style cards (with foil stamping, etc.): These cards have a strong sense of exclusivity and tend to command higher prices.

• High rarity unit group illustrations : Increased rarity value due to the inclusion of multiple characters.

These cards are in high demand among fans and collectors, and tend to fetch high prices in the secondhand market.

② Powerful cards that players are interested in

PC01BT is not a "ready-to-use deck," but rather its primary use is to strengthen and enhance existing decks .

• Key cards for a ShaniMas-themed deck : Main characters and support cards of the unit

• Powerful general-purpose cards : Cards with AP, general support, and buff/remove effects.

• High-rarity (SR/UR equivalent) battle cards : Cards with abilities that make them effective in battles.

In particular, players who already have a Shanimas deck can use PC01BT to reinforce their AP and key cards, creating a tournament-level deck.
