Every copy of the expansion includes either the hero or villain foil promo pack.
My copy of the Defenders expansion came with both hero AND villain foil promo packs (I mean, the 4 Hero main characters and the 4 villain main characters from the Defender set). So I guess I'm lucky for that.
If you get the A-Force expansion it includes both packs (of the Defenders characters, not A-Force).
Now I'm even more confused.
So A-Force expansion includes hero and villain foil promo packs from the Defenders (not A-Force) expansion?
