The story The Well has the following text:
Each player chooses one story card he has won (except this one) and shuffles it into the story deck. Then destroy all Day and Night cards in play.
The FAQ says:
If a card uses the word “then,” then the preceding effect must have been resolved successfully before the subsequent dependent effect can be resolved.
So does this mean if I trigger the story and I or my opponent does not have already won another story the first effect isn't completely resolved and the Day and Night cards will not be destroyed?
I would say so but my playing partner has a different opinion because it is a story and therefore the first then formula doesn't apply. He regards the first part of a first then effect as a cost and a story card can't have costs he says.
