I'll generate boosters for Limited and Ransac.
DF: Yes. I'm not sure if it's the case with Suitcase in general since I use Apprentice to generate boosters in other Mindmaster games, but a lot of duplicate cards seem to get generated. There was a time when your cards only differed by a couple commons, the rare, and an uncommon! Believe me, I kept generating until I got a (hopefully) minimal amount of duplicates.
EDIT: Ah, I see the "problem". There's only about 15 commons in the set, so of course duplicates are going to show up.
