Thanks! The idea is that you use the image on the tarot card as a basis for the prompt and go from there. Different decks are going to lead you to create different prompts because the art is different.
For example, I draw an ace of cups. In one deck, a hand is holding a goblet so I could interpret that as being offered a drink or having a drink with friends. If my character has a drinking temptation, I’d throw coins to see if they cave to temptation and have a drink or drink too much. Another deck depicts the ace of cups as a goblet hovering over a pond with a dove on top. I could interpret that as seeing a fountain in a courtyard if I was exploring a castle or coming across a secluded pond where I could rest.
