1. Directing Cry: it says add Nazgul to staging area or put it into play engaged with the first player. If the Nazgul appear under this matter, do I still need to make a Hide test?
Since it says "add" and not "reveal", the Hide test is not triggered.
2. Black Rider: After engaged player fails a Hide test, Black Rider makes an immediate attack. Do I need to deal 1 shadow card for this immediate attack?
