The New Enigma by Stephen Tucker

Four borrowed coins are set into the time honoured matrix and each coverd by a playing card. The one at the upper left vanishes and joins the coin at the upper right. Standart stuff so far.

Suddenly the unexpected takes place.. the two coins from the upper right vanish only to join the on at the lower right. 

Impossible as this sounds .. the three coins from the lower right now vanish and all four coins have assembled at the lower left!!
