Adding opponents in quest mode...

I'm going to bring up this topic here as well, since I'm not sure which forum is right for this question.
Adding a little bit to that... Will putting the decks in the /quest/decks folder allow them to come up, or is there coding that has to be done? I remember that there used to be the easy, medium and hard text files, but those went away some time back. I'd kind of like to be able to make my own opponents available as well. *shrugs*I'm wondering if it's possible for users to easily add opponents to go up against in quest mode. I've got about 6 of my evil creations that I want to be able to go up against in quest mode, and I'm not sure that the new methods allow me to add what I want. The decks I want to add are my Dragon deck, my Sliver deck, my Multiple Ways To Win deck, my discard deck, my Goblin Horde deck, and my Burning Elves deck. The deck files are in the attached zip if there aren't easy instructions for adding them. For the ones where there are multiple versions, the highest numbered ones are the most recently updated.
