were dabbled upon in Expedition, Aquapolis is the set to make use of them. Technical Machines would be released sparingly from this point onward. The Aquapolis set was also the first Pokémon TCG set to utilize the "Crystal Type" Poké-power. This power was written on the Aquapolis cards Kingdra, Lugia, and Nidoking, all of which are holofoil. It essentially allows the player to attach a basic energy card to the Pokémon and have it become that type for the turn. Note that this power does not allow the player to attach an additional energy card per turn. Of the 186 cards, the first 32 were designated with an "H" before the number. The 33rd card started at the number "1." Thus, the number sequence only goes up to 147 (the 3 "Crystal Types" take the number to 150/147). In addition, 4 cards received 2 versions: Golduck (50a, 50b), Drowzee (74a, 74b), Mr. Mime (95a, 95b), and Porygon (103a, 103b). These cards are identical except for the data they show when swiped through the e-Reader. Skyridge Skyridge, released on May 12, 2003, August 15, 2003, in both English and German respectively, is the 16th set of cards in the Pokémon Trading Card Game. Its symbol is a pair of mountains with a halo around the taller one. This is the last set published by Wizards of the Coast and has 182 cards. This set is the last of three to extensively use the e-Reader. Skyridge continues Aquapolis' tradition of minigames playable by scanning in dot codes from multiple cards. The Skyridge set was also the second and last set to contain Pokémon with the "Crystal Type" Poké-power. Characters in this set to use it were Celebi, Charizard, Crobat, Golem, Ho-oh, and Kabutops. These cards normally carry a much higher trade value on eBay and other online retailers than normal cards from this set. However, even normal cards from Skyridge are more valuable than normal cards from other sets, because Skyridge booster packs were very hard to find compared to other sets. The numbering system for Skyridge is similar to that of Aquapolis. The first 32 cards begin with an "H" and the 33rd card starts the numbering at "1", and thus the number only goes up to 144. The 6 "Crystal Types" take it to 150/144. There are no "a" and "b" versions in Skyridge as there were in Aquapolis. Skyridge
