Illusion - Mono Monday

Thanks to Marliesk for hosting today's Mono Monday challenge of Illusion. I thought I'd take a quick photo of some magic cards between putting up more pictures this morning and heading off to the cinema to see Passengers this afternoon (can't wait to see La La Land, but all sold out at the small local cinema). The cards can be used to create lots of different 'illusions', and the photo might give the 'illusion' I know how to do them (which I don't!). There's a clue if you look closely at the cards.
