When playing a Disciple, the option on the screen if you don't want to play a card is "Don't Throne." This is confusing for new players who have no experience with Throne Room. It should say something like "Don't play" or "Don't Disciple" instead.
My guess is both Disciple and Throne Room calls the same function in the back end, so as to not write two different lines of code. Maybe they can tweak the display language a bit. Not sure.
