People often mistake Oracle Cards as Tarot - but they are very different.
Tarot offers a 'real' look at the situations that are going on around you. It can be extremely specific in what it's trying to say to you. Oracle Cards on the other hand, are usually much much broader in their meanings, require a certain level of interpretation above and beyond tarot and are uplifting and 'fluffy'.
Some readers who use tarot also combine Oracle Cards with their readings as they offer vibrations of upliftment and positivity through a reading. They usually depict the 'silver lining' that needs to be looked for amongst the clouds.
Oracle Cards as a stand alone form of divination can usually offer guidance, support and positivity.
