To be honest have really no idea of about them but to be exact my points are

• As seen in the movies that there might be some people who can predict the future by those cards and they can say what lies in the future which is just a 50/50 chance.But some are out there who can really tell what lies beyond those are really hard to find.
• While there are many out there who just takes away the money from our pocket to theirs and made it a business.

If there are any results from those people than he/she might be worth a visit and so does that persons reading ;)
