The event Yoren's Task says: Any Phase: Discard 1 Night's Watch character from play to search your deck for 1 different Night's Watch character, reveal it, and add it to your hand. Then, shuffle your deck.
Ok, I am confused... Discarding a night's watch is a cost, but there aren't the magical words "cannot be saved". Does it mean that I can save that night's watch if I have in play Maester Aemon or Core Set Ghost and add to my and another night's watch?
My confusion origins from other cards like Old Bear Mormont: Response: Kill Old Bear Mormont (cannot be saved) to cancel the "when revealed" effects of a plot card that has just been played.
Ok, killing Old Bear is a cost like discarding a night's watch for Yoren's Task, but in this case the words "cannot be saved" are written.
Another question quite similar to me: the red viper of tales of the red keep says: If you are not running an Agenda, The Red Viper gains: "Response : After The Red Viper is killed, kill all characters in play."
Ok, same question: "cannot be saved" don't show on this card. But in this case I think it's a little bit different, because the text is not the same of Yoren Task or Old Bear Mormont.
Thank you in advance...
