Simplex Reverse Matrix by Mr. Pearl and ARCANA

Simplex Reverse Matrix by Mr. Pearl and ARCANA
Prepare to be fooled...badly. Mr. Pearl's handling of Ed Marlo's 'Simplex Reverse Matrix' is a masterpiece in sleight of hand with coins.

Four coins and four cards are introduced. The coins are placed together while the cards are placed one at each corner of the mat. In a fraction of a second, the coins disperse. Instantly, each card has a coin underneath it!

No shells are used.
Not difficult to do.
Completely ungimmicked!
Use any coins and any cards!
