Really minor nit: You could drop one of your nows.
Tangentially, my sons told me that when they start card tricks with an unopened pack of cards and strongly highlight that fact like it proves the cards have not been tampered with, the trick there is that card decks all start in the same order. So an unopened deck will come with a particular card order and they can know the order of the cards and can use that fact to help them with their card trick. It is part of how they fool the audience.
