I figured, it counts as two cards in the end of the game insted of one. That seems logical enough. Could anybody confirm?
I think I know the ones you are talking about. If so, they do count as two of that color but they must be the top card of that stack. If any other card is on top of it, then it counts as just one of that color
I believe they would also count as two towards goal cards in addition to the set collection
