This card (uk) is a status card that allows all uk prepared cards to be used as attrition cards. What does this mean? Since prepared cards can always be discarded for attrition costs, I assume it means that, with this status in play, they can be used to initiate attrition. But it must, presumably, mean cards that have no attrition symbols? So, do we assume that these cards are now considered to have one black attrition symbol?
