This is the description that I've found in several cards lately, specially from the new Queen of Dragons expansion set.
For example, one of it's plot cards say "you and an adversary must look for an accesory of your House in the deck". I think it called Expending the Winter Saves.
My question is: how does this work with the Neutral Faction house card?. This house card indicates that I have not a House affiliation, then:
A) The cards that talk about "cards of your house" mean the neutral cards for me, since my affiliation is neutral.
B) Such cards are useless for me, since being neutral means that I have no affiliation, and not even neutral cards are supposed to be "of my house".
Is A or B the right one?
