Robaire performs the ‘Triumph Effect’ at a private “State of Mind” mentalism show on June 29, 2018.
The Triumph Effect is when a deck of cards is thoroughly shuffled. Half the cards are turned face up, the other half remains face down, and these two halves are riffle-shuffled together so they are randomly intermingled face up/face down. Two spectators each choose a freely selected card from the mixed deck and put their cards back in while Robaire’s eyes are shut and head turned. They each shuffle the cards again. Then, while the cards are still in their hands (Robaire has not touched them since they were freely shuffled by the spectators), the spectators spread through the cards to discover that every card is now face down, except for their two selections.
