Deck Switch with Shell

A bold deck switch using a Card Case Shell was published by Stanley Collins in his trick “The Flying Sum and Divining Cards” in Will Goldston's The Magician Monthly, Vol. 9 No. 8, July 1913, p. 124. The shell is openly transferred from one deck to another in an off-beat moment. This type of switch was much later popularized by Dean Dill, who used it in his marketed trick “Blizzard”, released in 1997.

In 2012, Christian Engblom marketed “The Cooler”, a clever mechanical card case shell manufactured to switch a deck.
