The color, number, name and other information of the effective judgment card is the result of this judgment. When the referee card takes effect, it must be put into the discard pile. When you make a decision, the decision card is called "your decision card" or "your decision card" for short, so this card is not your own card (except skills, such as Guo Jia's "envy", etc. ).
