When a card escapes the shuffle, make a note of it, put it back in the deck, shuffle some more and continue your reading. If the card you draw means 'maybe', then it's a maybe. Let a week go past and try again. Meanwhile, take your popped out card and your 'maybe' card and put them side-by-side and see what you can learn from them. Journal what you see in the cards. Are they interacting? What do you think they mean? How might they apply to other parts of your life? Learning tarot is a journey - do your best to develop your intuition so that you don't have to rely on pages like this one.
Clarification cards are a waste of time. They simply add another layer of confusion. Avoid using them.
