Here's an underrated card that happens to be one of my favorites: the 3 of pentacles. It's not flashy or sexy. It doesn't promise huge windfalls or dramatic transformations. But it's an essential card.
This is the teamwork card. It can be you and one other person or you and a group. But it's not about doing your own thing. This card means you are in the process of building something solid. Could be a relationship, business, family, whatever.
The energy is about doing things correctly. There are skills to be applied. I pull this card a lot for clients who are working on something with long term potential. When they want to know if they are on the right track (financially or emotionally) and this card comes up, the answer is a definite "Yes".
But only because they've been working at it.
