What card best represents you/your personality (or, is most often pulled to represent you in a spread)?
That depends. Numerologically speaking, it’s the Hermit and the Moon, but I think the question is more about using a card as a significator, which usually means the Courts.
Two Court cards fall under this category, both in representing me and coming up quite often.
First, astrologically speaking, at least as far as the Thoth deck’s decans show, I am the Queen of Wands. This Court does come up pretty often, and I do, more in my public self than my private self, follow in her footsteps. I seem to be inspiring to others, particularly as a muse to other creative people. I am also good at public speaking and quite sociable/extroverted (love to chat!).
I also get the Queen of Cups in readings at random and am drawn to her as a representation of me. She fills all my sun-sign Pisces qualities quite nicely: I am very empathic and feel often strong emotional/energetic connections with other people. Great hugger. Unlike this Queen, though, I’m not so good at listening, although I’m told that my counsel can be very insightful.
Who I am at any given moment seems to depend on which is dominant, head or heart.
