Pokémon Advanced Challenge Trading Cards, released by Topps in 2004, is the second Advanced Generation set, drawing Pokémon from the first three generations. Its 90 cards run to 89 Pokémon (listed alphabetically) and a checklist card; Castform appears three times for its Fire, Ice and Water forms.
Foil parallels and the die-cut and pop-up chase subsets are not part of this numbered checklist. Card photos are added from contributor scans as the set is verified. Topps trading cards carry a uniform printed back, so each entry below has a single front-photo slot.
