Rider is one of the funniest gags for close-up card magic!
Simply place Rider on the table, with your arm extended towards the spectator in front of you. Apply a gentle pressure down with your hand or fingers and move Rider a couple of inches forward. When you release the pressure, Rider will skitter across the table, towards you.
Another idea is to have a regular deck and case on your lap. Remove Rider from your pocket and place it on the table, asking to the spectator to remove the cards from the case and shuffle them. When the spectator reaches with his hand towards Rider, you release it, causing Rider to fall into your lap. At this point you can make a switch and begin using the normal deck. Now you can begin your card routine.
