1. This card is usually the highest value of red, yellow and blue, which does not correspond to the card color, and there will be one more green. 2. Just upgrade the three values of this card to full, no problem. The reason why there are four colors is because there are four colors in the current songs, and the four colors correspond to songs. 3. It is a new pattern that the three mine roads do not correspond to the card color, so I won't say much here.
