I’m currently reading a few of the Pathfinder Harrow books, and I think this feat will help.
54 Card Pick-Up
You know how to use the Harrow, either to help or harm, but when you’re done you always get your cards back.
Benefit: When you use a Harrow deck in a way that destroys a card or cards, if you shuffle the deck for five consecutive minutes after the card is destroyed the card or cards reappear in the deck. These new cards are unmarked, and allow you to use the Harrow Deck for all feat, powers, or class abilities that requires a full deck of cards to draw from.
