vanishing card

My take on one of my favorite plots of close-up magic. With this plot, I notices a lot of weaknesses, so I tried to take most of those out. This can be done seated or standing up, and has other handling methods. (References cited as always)

I found this video while searching around for a force called the L'Homme Masque force. Anyone have any ideas about how it might work or the name of the techniques used?
