What does a witch use to see into the future?

There are so many different paths of paganism, and so many different forms of scrying, which is the term we generally use it describe looking into the future.

Each practitioner has a favorite form of scrying. My personal favorites include: palm reading - to read a specific persons future; pendulum - for finding things; cards (not Tarot) - for general use; a dark mirror - for Samhain.
