Can Taxed Dry be attached to Knights of the Hollow Hill? This just hit me when read the Taxed Dry.
"Attach to an opponent's income providing card. If it is Winter, attached card does not provide an income bonus. If it is Summer, when you count income you may also count the income bonus on the attached card."
It specifically do not restrict what kind of card type it can be attached to. I then thought that as Agendas are not in play, Taxed dry cannot be attached. But this attachment says CARD. And Agendas are cards. There are several other cards which says attach to a House card (House cards cannot be affected too). And even Mance Rayder can treat a North agenda card as if its printed text box were blank - of course on Mance the Agenda word is there.
Then I read the FAQ again and wondered that is it try to cancel the Agenda effect? (Agenda effects cannot be cancelled.) But Taxed dry do not cancel anything. It says how the gold providing card should behave in case of Winter or Summer.
So can Taxed dry affect Knights of the Hollow Hill?
