Pokemon TOPPS Advanced Challenge - Complete set 90/90 - NEAR MINT - 2004 In my opinion the cards are on average in NEAR MINT condition, but please decide for yourself. All cards are sleeved to keep them in this condition. Pokémon Advanced Challenge Trading Cards was a set of Pokémon-themed trading cards manufactured by Topps. This is the 9th TOPPS set out of 9 different TOPPS sets available. There were 90 cards in the set: 89 Pokémon cards and a checklist. Each of these 90 cards also had a silver foil card version. In addition, there were 28 bonus "chase cards" not included on the checklist: 18 embossed evolution cards and 10 pop-up cards. This listing is for the complete 90/90 Advanced Challenge set. The set Advanced Challenge is a mix of Generation 3 and 1 pokemon with: Pikachu, charmander, charizard, blastoise, venusaur, bulbasaur & squirtle.
