I've decided to design one for the Fool. (Some of you may remember I have trouble this card astrologically.) I think it would be fun to hear some different intuitions about this, so here's something of a game:
Pick any card you're drawn to and try to feel out an element that might be in it's chart.
For instance, I kinda see the Fool as an Aquarius Rising with Uranus in Scorpio near his Midheaven. Of course, I would be the one to think he's a solar Aries, but I'm having trouble placing the Moon and Pluto in the right signs/houses.
