Yes! It doesn’t matter what deck of cards it is, as long as it has pictures and/or words, ideally both. I’ll be working with my Aura Cards as one of my main demonstration decks, and all these have on them is a circle of colour with a word, but even these can be used to stimulate psychic visions, inspire insights and craft wise messages. I mention the Aura Cards because there’s a strong connection between the aura and crystals, both of which can help us understand the colour-based metaphors in oracle cards. We could do an entire course on colour alone when it comes to reading Oracle Cards!
