Why do you assume that it's always a Slashdance being sent out? You have no reason to believe that it will always be a Slashdance.
Sure, it's much more likely to be a Slashdance. But, that has nothing to do with the fact that you have to mail in for it. That's simply because Slashdance is the most common of the loots for this set.
You are getting the equivalent of what you were supposed to have gotten in the box. Is it annoying that you have to mail in to get it? Yes. That's why it's called a mistake.
Should Upper Deck go above and beyond and give you more than was promised because you have to mail in for it? While I think that would be nice, you shouldn't expect it, and complaining because you don't get more than was promised is a bit greedy.
