Is there some way to know what cards you have not owned in a set? For example, I am missing a few cards to complete the colletion achievements for Rastakhan’s Rumble but disenchanted the whole set when it rotated, so I can’t check my collection to easily see what cards I did not have at the time.
You can see what you don’t have by typing “missing” in the search box. You can’t see what you used to have.
