I've just learnt the effect 'Even more four on the floor' from Full Metal Jacket and at the end of the effect it is possible that you may have to use a magicians force to get the spectator to pick the card you want them to. This is something i've never been very comfortable with, especially when there are 4 cards. Does anyone have any suggestions on how to make it more convincing? I don't want it to be like.. Spectator picks the wrong card, you say 'OK, we'll lose this one', they pick the wrong card again, you say 'OK, we'll get rid of this one as well'. Then, the third time they choose the right card and you say 'So you want this one?' It just seems very unconvincing and quite obvious what you've just done.
