Hello. I need a force that will leave the card in the spectators hand (not to till them to take it but hand it to them unless it is sticking out of the packet) it needs to be very convincing and not almost impossible to learn. Thanks for the help.
I feel like most of the classic forces would fit your criteria.
-classic force
-timing force
-cross cut force
-slip cut force
-riffle force
-dribble force
