I fail to see the possibility of a core Tarot, especially as what we think of as the norm was solidified relatively late in Tarot history. There were several permutations and varieties over the years.
Yes but this is exactly what I mean....all those permutiations, in time, are seen to be now orbiting regularly about in this universe we call Tarot...they've become "normal". We don't have to visit those planets to be in the tarot universe, but we know they are regular things here in tarotville. That makes them standard stuff of tarot discussion....as in, "Here in tarotville, there are numerous flavors, but they are all sort of accepted as part of the bigger picture. You don't have to like chocolate, garlic, or pickled herring, just know that those flavors are often found orbiting around these parts..."
New things will be added, and in time, we will come to see them as "orthodox" as well, because they'll be good ideas and they will stick around in the neighborhood, just like Kabablah did, just like Astrology did. They will become "core"
