Bikes are mass produced and are sure to have some manufacturing errors. You could have just purchased several packs from the same batch, and it is possible that every box in said batch has the same issue.
Try purchasing a few packs from diffrent locations, or waiting a few weeks before buying a new deck. If that doesn't work then chances are it may be something else.
You can try rubbing the decks edges alongside your jeans a few times ALA Dan and Dave; I think that's already been mentioned.
You can try riffle shuffling them a few times, bending the bridge both to and fro as you go to losen them up.
You can also try placing a hot iron on them for a short time.
If none of that works, then try drinking about 12 shots of strait vodka. It will do nothing to improve the condition of your cards, but it will make your frustration go away for a few hours. =P
Hope that helps.
