I had an idea involving the erdnase steal that i wanted ya'll to give me your opinion on. The idea is to setup for the erdnase change and perform the steal pretending that you are going to change the card. You do it with "half" the motion of the change i.e. you cover the card perform the "shift" and don't do the follow through required for the change. Once the card is stolen bring your hand up to your face and talk to the audience and explaining to them that you don't know why it didn't change. Grasp your chin and tap on it as if you are thinking and then go back to the deck and complete the change saying you rubbed it the wrong way and use a lateral motion instead of a parallel motion. I know this is probably really hard to understand, but i am trying to be as discrete as possible in the explanation. If it isn't clear i could post a video showing what i am talking about. The reason i was thinking about this is because i feel like it cuts down on some of the suspicious motion that can arise during the erdnase color change. I kinda feel like it might be too much, but at the same time i think you can really throw people off with the chin rubbing business. Feel free to call it stupid.
