thanks for playing Targi. The power of that tribe card got a little scrambled in the translation. The German original version says: play a good of Your choice . So whaterver good You like. Therefore in that case You play a good of Your choice and are allowed to play that card.
We also had this question. The other thing that wasn't clear is, can you use this card multiple times over the course of those game after you have played it? We presumed that it was a permanent effect and could be used more than once.
