when your opponent plays a skull buckler and it kills one of your creatures, your creature becomes a 2|2 Elite Skeleton (which makes upped version worse in my opinion), but if you steal the buckler, and kill the opponent's creature with it, the creature becomes a regular 1|1 Skeleton. It happened versus Gold League.
I don't have a screenshot because I didn't know how to take one on a Mac, but I do now. sorry for lack of evidence, but maybe someone could post a screenshot here if it happens to them
