Double Back 2.0 | Jon Allen Tuchei Points to note: Stronger gimmickDouble Back is the strongest, most visual, and most engaging opening card effect ever created. A pair of 5s and a pair of Kings are shown front and back. You hand someone the 5s while you cleanly show the Kings. Instantly, you now hold the 5s while your helper now holds the Kings! Double Back is established as a modern day classic amongst 'packet effects'. There are a number of variations to Dr Daley's Last Trick, but this is the perfect version.
