Calling all Cards

An interesting routine, and probably worked as written when it came out. However, in order to work it now, you would need to rethink a few of the cards as they either look radically different or just aren't really in use. As to method, well, you probably know what it is if you read the description of the effect, and I will say that unfortunately there aren't any particular insights on the method at least as far as playing cards are concerned. I think it was probably excellent when it came out, but you would need to do a lot of work if you wanted to do it now.
