What is a card ribbon?

It’s the place of the card where the values for each action appear. Here’s an example:

Do: 2  Go: 1  Use:0 Talk: 3. In this case, the suit of the card is Use. The ribbon determines how many Life Points a player will lose at the end of the round. Depending on the suit of the trick, they will lose as many Life Points as stated in their ribbon.
