In the main story, the tower serves as the headquarters of the villainous organization Cipher, marking the climax of Pokémon Colosseum.
Scanning this Stage Card transforms the e-Reader battle room into a dramatic, final-showdown battlefield beloved by long-time fans.
Promo-Exclusive Virtual Trainer Cards

The two cards placed at the center of the set—
Hunter BIT and Team Snagem GAKU—
are promo-only virtual trainer cards not included in any standard pack.
BIT (13-P001)

Source:Mercari
“Hunter BIT” was distributed as a bound-in bonus within the free mini-magazine Pokémon Scoop 2004 Winter, released in early 2004.
This booklet was handed out at locations such as:
-
McDonald’s
-
Ito-Yokado
-
Toys “R” Us
-
Jusco
-
Daiei
-
Hello Mac
-
Pokémon Center stores
-
World Hobby Fair (Winter 2004)
Because it was a free booklet and easily discarded, very few intact copies survive today—making BIT’s card extremely rare.
Scanning the card unlocks BIT’s special double battle in the e-Reader room.
GAKU (13-P002)

Source:Amazon
“Team Snagem GAKU” was included exclusively as a tear-out bonus item in the official Japanese strategy guide,
Pokémon Colosseum Nintendo Official Guide Book (Wonder Life Special), published by Shogakukan.
This guidebook contained three major bound-in extras:
-
Pokémon stickers
-
Type chart and data materials
-
The Double Battle e+ card: GAKU
Because only those who purchased this guidebook ever possessed the card—and many copies had the card removed—complete sets containing both the guidebook and an unused GAKU card are exceptionally rare.
How Do You Use Them? (Scanning System)
-
Scan a “Double Battle e+” card using the e-Reader+ (Card e+).
-
Connect the e-Reader+ to a Game Boy Advance (GBA).
-
Use the GBA–GameCube link cable to connect the GBA to the Nintendo GameCube.
-
When launched, Pokémon Colosseum expands, and new special double battles become available.
This three-tier system—
“Card → GBA → GameCube”—
allowed the game to evolve through physical card interaction.
Required Hardware (What You Need to Use These Cards)
To play Double Battle e+, the following equipment was required:
e-Reader+ (Card e+)
A dedicated device used to scan the e+ cards.
Game Boy Advance (GBA)

Source: Nintendo
The main hardware used to mount the e-Reader+.
Nintendo GameCube (GC)

Source: Nintendo
The console running Pokémon Colosseum.
GBA–GC Link Cable
A special cable used to connect the GBA to the GameCube.
→ Because this full setup was complex and expensive for the time, very few players actually had the complete environment, which is one major reason why today’s card population is extremely limited.
Why Is This Product Special?
-
A rare system for its time: “Scanning physical cards to expand the game.”
-
High entry barrier → only a small number of people ever used it.
-
No overseas release → demand from international collectors is extremely high.
-
Very few complete sets survive → full sets are exceptionally rare.
-
Represents Nintendo’s experimental era in the early 2000s.
→ Scarcity × Uniqueness × Historical significance
make this a truly premium collector’s item.
What Is Pokémon Colosseum?

Source:Amazon
Pokémon Colosseum is a stylish and dark Pokémon RPG representing the GameCube era.
It was released on:
-
November 21, 2003 (Japan)
-
March 2004 (North America)
Unlike the bright, adventurous worlds typical of Pokémon at the time,
Colosseum boldly introduced a darker, more mature world—a major departure from the series’ norm.

Approx. 340,000 units sold in the first week

What Kind of Game Is It?
1. A protagonist who is a former villain—an unusual premise

Source: Pokémon Official Website
The protagonist Wes is a defector from the villainous team Snagem.
His cool, shadowy persona was a huge hit among Western fans who loved more serious storytelling.
2. A story about “saving” Shadow Pokémon
The key element of Colosseum is the Shadow Pokémon concept—
Pokémon whose hearts were artificially sealed by the villain organization.
Players must:
-
Snag (capture) Shadow Pokémon from enemies
-
Purify them to restore their true selves
This narrative—rescuing corrupted Pokémon—became one of the series’ most dramatic storylines.
3. Every battle is a Double Battle
All main battles are 2 vs 2 double battles, providing deeper strategy and synergy.
This system influenced future Pokémon titles, helping popularize double battles in the main series.
4. Fully 3D Pokémon battles

Source: Pokémon Official Website
In 2003, real-time 3D battle animation was groundbreaking:
-
Detailed attack animations
-
Stylish character designs
-
Cinematic camera work
Overseas fans often describe Colosseum’s visuals as “god-tier” for its era.
5. A Connected Series: Followed by Pokémon XD Gale of Darkness
The success of Colosseum led to the release of its full sequel:

Source:Amazon
Featuring:
-
Expanded story
-
New Shadow Pokémon
-
Improved game systems
Its iconic “Shadow Lugia” remains one of the most beloved designs in Pokémon history.
Relationship to Double Battle e+
One feature that enriched Colosseum’s popularity was its expandability through the e-Reader+.

Source: Nintendo
Scanning Double Battle e+ cards allowed players to access:
-
Special new trainer battles
-
Stage variations
-
Unique rewards
This physical-to-digital connection gave Colosseum an identity as
“the Pokémon game that evolves through real cards.”
Overseas fans often say:
“Colosseum marked Pokémon’s first step into a more mature world—
and Double Battle e+ was the secret key that expanded that world.”
Why Is This Product So Valuable?
① Extremely hard to obtain even at launch

Source: Nintendo
To use these cards, players needed:
-
e-Reader+
-
Game Boy Advance
-
GameCube
-
GBA–GC Link Cable
Because the full setup was expensive and complicated, the number of active users was extremely small.
As a result, the total print and survival rate of the cards is exceptionally low.
② Very few mint-condition cards remain
Because the cards are made of paper, they are prone to:
-
bending
-
surface scratches
-
scanning marks
Finding clean, unused, or lightly used cards is extremely difficult.
③ A full complete set has “miracle-level” rarity
Collectors consider complete sets to be the highest tier of rarity,
and overseas buyers actively search for them.
④ Overseas re-evaluation is booming (especially in North America)

Source:Amazon
While Pokémon Colosseum has strong global popularity,
the e-Reader system was discontinued early overseas.
This means the Double Battle e+ cards never released outside Japan,
making them “phantom extra content” for Western players.
This exclusivity has caused demand—and prices—to surge rapidly.
⑤ Boost from the retro gaming boom
Recent trends:
-
Nintendo retro boom
-
Renewed attention on GameCube titles
-
Rising interest in obscure physical add-ons
All of these contribute to the growing demand for this product.
