8. 1998 Japanese Promo Card – Tamamushi University Magikarp Trophy

This surprisingly epic Magikarp promo card was only given out during a two-day tournament event in Osaka, Japan, but only to competitors who managed to win at least one battle. To participate in this event, you needed to complete the “Tamamushi University Hyper Test,” which was briefly published in a select number of magazines. What did the questions entail? We don’t know, as there’s not much info online, but presumably, the test was Pokémon-related. After all the tests, 1000 fans who scored highly on the tests were invited to the Osaka event. With art drafted by legendary Pokémon artist Ken Sugimori, the card displays a Magikarp leaping through the air while shooting a bolt of lightning.
