Use this chart to record any Treachery Card information you may happen to gain. Record the information by writing the letter of the card holder in a space to the right of the card's name. Also, write D for cards which have been discarded. Knowing what cards an opponent might have, even if by process of elimination, before a battle can be extremely useful. This is especially useful for the Atreides player who gets to look at cards before they are purchased, but may be handy for others. For example, if the Atreides player has spice and room in his hand and yet does not bid at all on a card, one might reasonably guess that the card is a Worthless card and write the initial of the buyer along with a question mark next to the card name.
