If you pulled every possible combination of just 3 cards with reversals, you’d need more lifetimes than there are grains of sand on Earth to read them all. Even a single card draw gives you 144 possible messages when you include reversals.
That’s a lot of nuance when you’re looking for a simple yes or no.
The complexity multiplies fast with each additional card in your spread. For those seeking binary clarity, the tarot community has some workarounds. Many readers use a pendulum, while others have a special coin for divination. Some people use silver coins because they think it adds something extra.
The cards are good at telling stories, but sometimes you just need a straight answer. You might want to read this thread to understand what this really means a bit more.
