Hi long time lurker, first time poster. I bought 10 loose Rebel Clash boosters from a game store and only got one v card in all these packs. That's it no vma's, gxs, full arts nothing. Bad luck or is it possible for a store to dump boosters they suspect duds?
It's poor luck, like @CrownAxe said you wouldn't have gotten a single thing if the cards were weighed or tampered with. You're playing with odds whenever you open packs, which is part of the reason I go with singles most of the time unless I find a really good deal on a product or something.
