Do as I Do under impossible conditions. It looks very fair

An impossible coincidence, a powerful mental effect.
Two regular and shuffled decks! Really simple and fun to do.
The spectator takes any card from one deck and the magician does the same from the other deck. The amazing thing is that the magician and the spectator surprisingly took the same card!
A vatiation "Do as I do" with an interesting and fascinating technique!
