Here's a simple idea, the Yes / No divination card. Kinda like flipping a coin but with a calling card! These are available for free, only from me. Come visit at a reading and pick up a few!
That way you'll have a "deck," mix them up, ask your question, and draw a card.
If you only have one, I think you can bend it so it spins. Flick it, stop it when you ask your question, and voilĂ ! Your answer will appear.
