Symphony is a devilishly-deceptive divination of two selections from a shuffled deck.
Peter Turner is known for bold methods but Symphonys simple construction means its almost self-working.
The spectators shuffle the deck before and during the routine and impossibly youre able to tell them what freely selected card theyre both thinking of.
As a kicker, the chaos corrects itself as the deck comes back into perfect red/back order except for the two selected cards.
Symphony is 100% sleight-free and a massive fooler.
