The DP Black Star Promos are a collection of promotional cards tied in with the Diamond & Pearl series of cards, which started with the Diamond & Pearl expansion. It is the first series of Black Star Promo cards to have a numbering prefix (DP).
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.
You will receive the EXACT cards shown in the images - no deck box, coin, or manual included.
