Lore

Why it matters

This card is a notable example of the "TAG TEAM" mechanic introduced in the Sun & Moon era, which allowed two powerful Pokémon to share a single card. Its appeal lies in the whimsical contrast between the tiny, notoriously weak Magikarp and the massive, high-HP Wailord, making it a unique and visually striking piece for collectors of water-type deck staples.

Provenance

Where it came from

The Magikarp & Wailord-GX card was released in 2019 as part of the Pokémon Trading Card Game's Sun & Moon series. It was distributed specifically as an SM Black Star Promo, numbered SM166, serving as the centerpiece of a dedicated collector's tin. This card was designed to capitalize on the introduction of Tag Team-GX mechanics, which allowed two powerful Pokémon to appear on a single card, reflecting their synergistic relationship in the game's competitive meta.

The artwork was created by TOKIYA, a veteran illustrator for the Pokémon TCG known for a vibrant, stylized approach. The design emphasizes the immense scale of the Wailord alongside the iconic, diminutive Magikarp, creating a humorous yet visually striking contrast. Upon its release, it was well-received by players and collectors alike for its high health point total and its playful subversion of the traditional power dynamic between the two species.
