Shopping is an Integrity deck specific effect card.

When used, you will spend all your gold to summon a random monster from your deck that has a cost equal to the amount of gold you spent. Keep in mind that it doesn't work if you have no monster with that exact cost, that it takes in account cost changes like Slowing and that you will activate your passive from doing this.

This can be helpful alongside cards like Fortune and Burgerpants, who will give you money so you can manage what monster you want to summon. Break can also help to give room on your board as well as give slightly more G.
