This card was included in the Diamond & Pearl expansion, first released in the Space-Time Creation expansion in Japan. It was reprinted in the Secret Wonders expansion, previously released in the Japanese Dialga LV.X and Palkia LV.X Constructed Standard Decks.
Rival is one of the only Supporter cards in the DP Era of the trading card game with a name in which the second word is not a possessive of the first word, the others being Professor Rowan and Fossil Excavator.
