Item cards (Japanese: グッズGoods) are a subclass of Trainer cards. Item cards, as the name suggests, depict items, typically from the Pokémon games such as the Good Rod and Moomoo Milk, which a player can use once to have some kind of effect on the game, and are then discarded. Players are allowed to play as many Item cards as they wish during their turn. Pokémon Tools and Technical Machines are also classified as Item cards. Much like how Supporter and Stadium cards changed their colors to red and green, respectively, Item cards changed to blue. Many Item cards have seen multiple releases and illustrations since Item cards debuted in the HeartGold & SoulSilver expansion. There are currently 316 different Item cards, though many have been printed multiple times with different artwork.
The concept of Item cards as a distinct subclass of Trainer cards debuted in Japan as "Goods" cards, with the release of the HeartGold & SoulSilver Collections at the start of the LEGEND era. The English releases did not adopt this name change right away, and continued classifying them as Trainer cards until the release of Black & White. However, they were still considered a distinct class of cards separate from earlier Trainer cards released beforehand, and separate from Stadium and Supporter cards. Therefore, that new class of Trainer cards, as well as all previous Trainer cards that were not Supporters or Stadiums released beforehand, have since been redefined as Item cards, and as a subclass to the overall class of Trainer cards.
