Amazing Card Change Sleeve

This is one of the most amazing close-up "illusions" to have appeared in recent times.

Effect: a playing card in a clear plastic sleeve instantly changes into a completely different card without any cover.

You may also use the sleeve to produce or vanish a card.

The change is visual and takes place in an instant under the audience's nose. You can hand over the changed card for examination, and show the clear sleeve completely empty at the finish.
