There are several websites for creating Pokemon cards with custom images and text, including My Poke Card, Pokemon Cardmaker and Pokemon Card Maker. These cards look like the official trading cards and can be saved and printed later.
Images uploaded to any of the above sites can be used as the main image on the Pokemon card. The text on the cards can also be changed. The name of the Pokemon, HP and descriptions of their attacks are editable. Users can also modify the type of card, with different elemental colors and energy symbols available in the top right corner.
