Kneel and sacrifice The Kingsroad to reduce the cost of the next character you marshal this phase by 3.
Kneel Skagos and sacrifice a standing [Stark] card to search...
It's stated that costs happens simultaneously and not sequentially, and we all assumed so far that Kingsroad can work. But how about Skagos? Can I kneel and sacrifice Skagos? Since Kingsroad can be both kneel and sacrificed at the same time, can Skagos do that thing too?
I know it requires a standing card, but there should be no check during the execution but only before. Am I missing something?
