shadow card

angelika

Hello everyone. Can someone explain to me how they define the 'shadow card'. I have been thinking it is the bottom card after the deck is shuffled and you are ready to lay them out and therefore it is somehow the one furthest away from the 'answer'. But sometimes this card seems incredibly useful and not the furthest one at all. I notice people refer to this quite a lot. Or is the shadow card some other reference?
