POP Series 9 was the first promotional set of the Pokémon Organized Play program to be released during the PL Series. Similarly to POP Series 6 and POP Series 7, the entire set is made up of Pokémon. Unlike these previous sets, however, all of the cards except Gible were new for the set.
While the set includes no Trainer cards, many of the cards featured have attack effects that rely on other Pokémon also in the set to be in play, making them somewhat useful in multi-type decks. This comes around from the fact that these cards were released as part of a "Collection Challenge" campaign in Japan, and were likely purposely made to complement each other.
Each pack includes 3 cards; two Pokémon and one basic Energy card.
Several Canadian Leagues awarded packs to players at the end of February, earlier than the intended release date.
The rare card Rotom also had a holographic version that came in the Rising Rivals Value Pack; a reverse holographic version of Raichu came in the Supreme Victors Value Pack.
The rare cards Regigigas and Manaphy also have a holographic version, both came on Supreme Victors blisters.
The uncommon card Lopunny has a holo version that came in the Arceus Blister pack.
Although this set was not released in French, most of the cards were released in France as Promos in various blisters, with an exclusive Cosmos Holofoil. These cards are Manaphy 2/17, Raichu 3/17, Regigigas 4/17, Motisma 5/17, Cradopaud 7/17, Lockpin 9/17, Pachirisu 10/17, Pichu 11/17, Ouisticram 13/17, Pikachu 15/17, Tiplouf 16/17.
The POP Series 9 set was released in English, German, and Italian. This set was not released in French, but most of the cards were released nonetheless as Promos, with an exclusive Cosmos Holofoil.
