Main features of EX13BT

1. A new color, "yellow," has been added.

This set introduces a new color, "Yellow," allowing players to build decks based on their school year, enabling deck construction that takes advantage of the unique school year synergies of the Idolmaster Academy series. Since it also includes enhancement cards for existing colors, this pack is highly valuable as an update even for players who already own an Idolmaster Academy deck.

2. All idols' newly drawn illustrations and signed parallel cards

This set features newly drawn illustration cards of all the idols wearing special Union Arena costumes, making it a highly collectible set. Parallel cards with foil-stamped signatures are available for each idol, including Saki Hanami, Temari Tsukimura, Kotone Fujita, Tsubame Amayo, Mao Arimura, Liliya Katsuragi, Chika Kuramoto, Kiyoka Shion, Hiro Shinozawa, Seina Juoh, Misuzu Hataya, Yume Hanami, and Riha Himezaki.

3. Limited edition AP card with serial number

A limited number of limited Action Point (AP) cards with serial numbers will be included, and these cards are expected to be autographed by the cast members. It is currently undecided whether these cards will be included in subsequent releases, and they are likely to become highly sought after as rare "super prize" items, especially in the initial production run.

Popular cards and potential winners

*At this point, the official market price and environmental evaluation for each rarity may change after release, so it is advantageous from an SEO perspective to structure the article by describing them as "candidates" or "assumptions" and adding/updating them after release.

The following cards are considered to be among the most desirable pulls. (Card names are organized based on the high rarity, parallel, and AP versions of the idols mentioned above.)

• Foil-stamped signed parallel (★・★★・★★★)

  • Signed parallel cards of your favorite idol tend to fetch high prices due to the character's popularity and rarity.

• Limited edition AP card with serial number

  • Given its extremely low inclusion rate and the planned inclusion of an autographed item, it's likely to be one of the top prizes in this set.

• New color "yellow" key card

  • Leader cards, search cards, and finishers that form the core of a grade-level deck tend to see increased demand depending on the current metagame.

summary

The Idolmaster Academy Vol.2 [EX13BT] is a booster pack that is attracting attention for both its collectibility and practicality, thanks to the addition of a new color "yellow," newly drawn signed parallel cards, and limited AP cards with serial numbers.
