I have had something like that happen before with a pack of Expedition before. Unfortunately, those types of cards generally are not worth anything, due to the fact that it is a printing error more than anything else. If you talk to PUSA about it, they should hopefully send you at least 1 replacement booster pack.
Off the record, EX: Deoxys is one of the worst sets to be printed I have seen; many of the cards that I opened at the PR had foil peeling off, white splotches, and cards bending.
Yeah, definitely mention to Nintendo that you received a faulty booster pack that had only 6 cards and a couple of misprinted cards. This should not be happening at all.
