Gwent spy cards can be placed on your opponent's battlefield (and count towards your opponent's total) but allow you to draw 2 extra cards from your deck. The Monster, Scoia'tael, and Skellige factions don't have their own spy cards but can make use of the one neutral card and any that are played by their opponent.
