A new Diamond and Pearl “Power Pack” will be sold starting this July, featuring exclusive holographic energy cards. You will only be able to find them at small stores, hobby shops, and perhaps the internet, but not at major chains like Target; plus, there are very few of them that will be printed (only 36,000). The warehouse description for the product is below. Booster pack sets named are the primary ones that will be included in each power pack, but there may be substitutions from other sets.
