No matter where you are, poker cards are required. The marked decks were originally designed for magic cheating. They were later used to prove marked decks are prohibited in casinos.
Choose a deck that is marked and of high quality. The Aviator marked cards from GS are an excellent choice. These cards are available in either blue or red, and they can be marked with black or white marks.
You can choose from a variety of colors for the contact lenses that cover your marked-deck. We need to know what color your eyes are so that we can suggest the right contact lenses.
