A really strong packet trick
Look the second version with blank cards So, If you cannot find the gaff cards, you can do it also with blank cards.
This effect is a tribute to the bicycle supreme line. Really amazing! A crescendo of magical effects! Five seven of clubs with red backs mysteriously turn face down one after the other.
Then the magigian shakes the packet and all five seven of clubs instantly change into disorder. And finally the five cards change color on the back.
