Shanera just asked me this like two days ago... My theory for Collector's Device (the English name for the first collection you're talking about) ...Is the fact that it does give the Owl which is 100% more Experience when playing and only one or two cases have it as a reward. They probably don't want people leveling up too fast with using the Owl.

As for the others, I dunno. I'll email support sometime next week and ask about it.
