So, I'm in the middle of making my own tarot deck and I've over half the amount I need of blank cards to decorate. I've looked at images online of all sorts of tarot cards from goddess to erotic to traditional to fan art. And I've seen quite a few images with cards like "mother" and "boy". But, looking at a list of cards and suits for tarot, I found no Mother card. The closest thin I found was the Empress, who's seen as a motherly figure. So, I was just wondering... Is there really no "mother" or does it just depend on the deck and preferences of it's owner/creator?
