The anomaly of the lobby was having another hero power. I chose Marin for my first and master Nyugen for the second. In the 7 coin turn, the options of master Nyugen suddenly appears only one option, which is the rat king hero power. Every turn after that, before choosing the next, it appears as master Nyugen’s hero power. The option is just a different minion type of the rat king’s hero power, and there is only that option.
