It is Walmart, but I'm just saying that 8000 hp is unlikely. I don't mean to offend you or accuse. I just have bought packs that I thought were real and weren't.
The one series of Black and White last year all the cards had high HP. My son said all the cards in those packs had high HP. If you would like to gather enough people together we can sue the card company for putting fakes in their own packs.
All cards came right from the packs last year. My son just started collecting them last year. The Black and White card packs at Walmart all ha high HP.
