Some uses for those extras (for you or others):1) Build more decks at the same time
2) Have different encounter decks ready at the same time
3) Get a third copy of cards that the Core Set has only two copies of, without having to buy a full second Core Set (one will still lack the ones where the Core Set has only one copy, but it's still something)
4) Use them as cardbacks for printed custom cards
