Are tarot cards a mortal sin?

I'm curious, do you really believe that tarot cards constitute a mortal sin? As a practitioner in the field of cryptocurrency and finance, I'm sure you understand the importance of rational thinking and fact-based decision-making. Tarot cards are simply a tool for divination, a form of self-reflection and guidance. They are not a religious or spiritual practice, and therefore cannot be considered a sin in any traditional sense. So, do you think that tarot cards should be categorized as a mortal sin, or is that a bit of an overstatement?
