This isn't the first time this has happened. The Gozanti advertised three copies of each of the huge ship only modifications. But they only packaged two each in the final product. We got some more missiles instead.
The Raider too, showed cluster missiles in the advertisement, but instead came with prockets. None of those have been TOO egregious for me personally. But it is annoying. Especially when your purchases are determined by how many copies of a card you assume you'll be getting based on an advertisement.
