Our first action card. Mirrors were popular things during the season. Used for communication, for special displays, and transportation, among others. And while you won't be able to use mirrors in the card game for imprisoning your opponents and forcing them to face the dark halves of their loved ones, you'll be able to make any trip just a hop skip and a jump if your character can get some alone time (controlling the locations) to set them up. Is it handy? Yes. Is it worth taking up 2-3 slots in your deck? That depends entirely on how much delicious pain you want to dish up from sneak attacking your enemies...
