Collectible Card Game Headquarters

Hi, I'm trying to duel against the AI with a random pick of my constructed decks, but I can't find the option to other than the folder icon, which sometimes picks my decks but most of the time picks the pre-built decks that came with the game.

This is not possible at the moment since Magarena picks random decks from '<install folder>/Magarena/decks' including sub-folders. I have updated the to-do list but a temporary workaround for now is to move (or zip/rar/7z) the sub-folders so that only your custom decks can be found.
