I am rarely using the Magic Workstation lately due to its lack of support from the online community and with the trend of new MTG gaming platform. The program was used solely for building deck brews offline though I still try to update the card database from time to time.
Recently as I have noticed in the forums, it got rarely used and visited as most of the new players preferred newer and more interactive platforms for deck building. However as for my personal preference, I do try to update and share if I ever found some patch files.
After Googling some file sources, I have found this .txt file which you can add through the Add Set under the Tools panel. You can download it here.
As of this posting, there is still no text file available yet for download so we might need to wait for someone to post it in the forums. I will update this blog post once I have found one.
