From a borrowed and shuffled deck a spectator finds his own selection by summing three randomly selected cards.
David Jonathan has completely restructured and reworked an old math principle to make it very deceptive. He removed most of the spectator card counting sequences and thus turned a counting and procedure-heavy trick into a stunningly effective and hard-hitting card routine.
"What David has done with THREESUM is nothing short of incredible! Seriously, no smoke blowing here. How he managed to take an old principle in card magic, remove all the procedure and dress the diabolical secret in a super direct and commercial routine, I'll never know." - Kyle Purnell
"David has taken a clever if slightly underwhelming effect and turned it into a lean, mean, mind-bending machine. So freaking clever. I love this trick, wish I had thought of it!" - Cameron Francis
is a super direct and powerful routine with a regular shuffled deck. Best of all, as unbelievable as this may sound, it requires no setup, every selection is a genuinely free choice and it is 100% impromptu. This is all thanks to the ancient principle that has been unearthed and entirely reworked from the ground up to create this deceptive miracle.
Here's What Happens: The performer tells the audience that they will perform an effect. From a shuffled deck, any card is selected, remembered, then returned in the pack, which is shuffled further. The participant now removes any three cards from the deck and the values of each are summed. They count down to this number in the deck and miraculously find their chosen card at that exact position!
