Checking their previous SO-DO listings (including their most recent ones such as the Gaim PB sets), they don't do this either; they just list exactly the figures that are in the set. When it comes to other retail waves like Den-O 2, they do say there will be duplicates as with all retail waves, but nothing about randomisation.

They put up listings for the PB Mirror Monster sets too (at a double price markup, of course), and they don't have anything like this either. This is something wholly unique to their Ryuki Wave 1 listing.
