I also checked the RotK rulebook. It is not there. I appologise. I remebered at the release of RotK we had a tournament and the has been a big manuver argument i which 2 players next to me needed a juge, I'm pretty sure
grima wormtongue was involved but I must be mistaken on what the ruling was. All I now is a juge took the RotK rulebook and called the ruling for the shadow side. I listened to th whole thing since my deck involved a lot of maneuver and I had it since towers (duntless hunter).
Anyway, since I also started to had doubt, I checked and couldn't find it, but now I'm curious to know what did happen during this tournament.
