Four Kings are on the table, one selection is out-jogged in the middle of the deck. Just one second, one King vanishes and the selection became the lost King. But it's an illusion because magically, in the middle of the deck is still the selection, and on the table there are still 4 Kings. At the end, the selection and 4 Kings switch position in light-speed. Ending clean.
