I've read it. But how to add cards to the deck it doesn't say.

Stop figured out the map should automatically get into the deck But if you have an older version of the game you must first pass the card to his companion, and then take the inverse on the result of the map will land you in the stocks.

In a pancake, and I forgot that there is a caravan this... Many times through the game, and the cards are not played)
