The term 'Deck with Pentacles' is referring to a Tarot deck, which is a set of cards used for divination and fortune-telling.

The Minor Arcana is further divided into four suits, one of which is Pentacles. Therefore, the term 'Deck with Pentacles' is referring to a Tarot deck that includes the suit of Pentacles in its Minor Arcana.
