Juan Tamariz brings us another phenomenal effect. The spectator chooses four cards from a shuffled deck - red are good luck and black are bad. Card after card is turned over and revealed to be black, to the shared chagrin of the magician and the spectator. As the trick culminates, the magician visually changes all the black cards to red, bringing good luck to everyone.
Bad Luck is an excellent example of the importance of presentation and routining. The possibilities for presentation are incredibly diverse, and the potential for intimate audience interaction makes this trick an amazing treat.
Juan Tamariz is without a doubt the single most important person in our field today. His thoughts on the art are far and away the most profoundly significant advances happening at present. Not since the Professor, have we had someone look so deeply, see so clearly, or push the art forward so enormously as this great gentleman. Although only a tiny fraction of his ideas and thoughts have appeared in print in English, what we do have is of immense value. His books, The Five Points in Magic, The Magic Way, Sonata, Verbal Magic, and Mnemonica, are some of the most valuable books in the entire lexicon. Mr. Tamariz also has some video offerings available, most important of which are the films of his excellent lectures. Any opportunity to learn from him will be to your utmost benefit!
