This is a very clever bit of thinking which gives you a trick that will get you at least a modest amount of applause at the end, it may even get far more!
The reaction does really depend on the group of people but generally it is very good, it will get you the best reaction possible from the particular group of people.
This is easy to do and a great way to close a performance to a group of people.
There is no skill involved here this is a trick you present and it basically works itself as long as you follow the instructions which are minimal.
The main advantage of this over lots of other similar tricks is that they can name any card making it repeatable with a different outcome each time.
Add to this it involes three people you have atrick that really pulls people it and gets them interested.
If you perform to groups of people you must get this.
