POP Series 8

Pokémon POP Series 8 was released by Pokémon USA in 2006. It was the eighth installment of the POP series and contained 67 cards of some of the most popular Pokémon from the series. The set features two different kinds of cards – POP cards and regular cards. POP cards had gameplay elements and featured sketches of characters on them, while regular cards featured art of the characters and featured an ability or attack.

The set featured some of the more popular Pokémon from the time, such as Charizard, Butterfree, Gyarados, and Gyarados EX. POP cards illustrated the card's abilities in detail, including attacks and moves as annotated illustrations. Regular cards had colorful images of characters that belonged to either the Grass, Fire, Water, Electric, Colorless, Dark, or Psychic-type.

The set also featured a special reprint of the Gyarados EX card from the EX Delta Species set, which was the first card to have a special text that stated "This Pokémon is not eligible to compete in sanctioned play". The reprint of the Gyarados EX card was released to show the changes made to the card after it had been banned from competitive play.

Overall, Pokémon POP Series 8 was a popular set and it contained some of the most recognizable Pokémon at the time. The unique illustrations and gameplay mechanics of the POP cards made them an instant hit with collectors and competitive players alike. The reprint of the Gyarados EX card was a nice bonus and provided an interesting example of how Pokémon cards are altered when their usage in competitive play is restricted.
