I have been a card magician for 4 years now, so take this into consideration. I would cut this down to a 5 phase build up routine. Why? Because (no offense) I started to get bored because of the length and also it was the same result every time. Like to a laymen in his mind its like "oh, that's clever" you don't want that... You want it to be "MAGICAL" I say this because its cool a monte routine where they always get it wrong but where is the magic in that? You don't want to produce the same result for two to three phases of the routine like when you are saying, where do you think it is? in the middle? you would be wrong. etc. Cut it down and make a buildup. What I mean by that is start making the tension rise and don't let them be able to expect whats going to happen next for example getting the card wrong again, make it appear somewhere or do a 3 card color change or something to leave them messed up. I would go with changing the cards like u did in the first where you followed the ace of hearts, and then I would change the backs like maybe 2 silver monarchs and a blue bike or something. The point is, make them want to see more and just be mystified with every phase. I would do 4 phases actually maybe 5. Check out Recoil by Ollie Mealing, and Fade by Chris Mayhew
