But… I was able to throw together a super easy PowerPoint file that has all the cards (Minion, Elite, and Master) and symbols I could think of to be able to make just about any Homebrew adversary you could want.
Tossed it up to Google Drive, which messed with the symbol placements a bit, but should be good to go if anyone is interested in making some new bad guys to face while we wait for more official content to drop.
