Nineveh
I just want to add that I also believe the Tarot is very good at answering yes/no. It's all about having a technique to which you read a yes or a no and you stick to it, and your cards "react" well to it... which, luckily, mine do.
Yes, for me the sun and 10 of cups are automatic 'yes' cards. If those don't show up, the cards show me the bigger picture as in what is taking place or what will happen prior to. Thanks.
