You can't.
There are 19 Card Clues. To get a Card Clue, collect all cards in a Card Combo by purchasing books or card packs. You can find the Card Combos on your Clue Map, or through the Combo button in My Cards.
You have to add the cards of the books and card packs. Card combos unlock clues. Complete the missions to unlock more clues. When you have all the card combos complete and you have played all missions you will have all the 39 clues. Don't use the replicator cards if not necessary. Use them when you need to unlock a card when it has not been unlocked even after you have added all the cards of the books and card pack.
