Other Flourishes: These are moves not do not fit in the other categories. These can be springs, dribbles, faro effects, and more. Although cardistry is virtually always done using playing cards, some occasionally choose to perform or practice flourishes using what is referred to, broadly, as trainers. Many attempts have been made to produce trainers as a cardistry product, and alternative to playing cards. One notable example is “Squids”, an elusive and high end product that was privately developed by Chase Duncan; an early pioneering cardist and magician who consulted for a variety of stage acts, particularly in Las Vegas. In Cardistry, he is widely considered to be one of the most talented and well known figures and is responsible for numerous ubiquitous flourishes and a few that are considered to be extremely difficult to master.
