I started out with the Classic Rider-Waite and then progressed to a "modern "deck (Mary Hanson Roberts) Which I am not completely happy with either but I like the colours and the pencilling
I pay *a lot* of attention to reversed cards and see them as more personal and emotional and "hidden" ( from my own self ie unrecognised by my conscious mind) than uprights.
I use the classic Celtic spread but just as often one called Diana's Arch that I read about in a feminist spirituality journal way back in the 80's which I find useful because with it I have to take my intellect off the hook.
