Is this only about the Egicipios Kier? Or Egyptian Tarot styles?
I realized after I wrote the information below, that someone began discussing the Egicipios Kier...I agree it is hard to analyze a decorative Egyptian deck because it takes awhile to really figure out sometimes among the different publishers what might be the 'house style' of their system and what might be the author and artist's creation or system of thought.
The example below is how creative and different Egyptian tarots can be. One examples is the Sylvia Alasia designs for the Egyptian Tarot from Lo Scarabeo.
1. Egyptian Tarot-- Sylvia Alasia
The majors are said to follow the Falconnier-Wegnar (may have check spelling)designs and I believe the "Church of Light" reproduction majors follow the same design in the majors:

Recently I was looking at my CC. Zain book of tarot - with his astrological/mystery school ideas of the occult thought--and realized the "son of earth" kind of picturesque language was the origin of how Lo Scarabeo summarized the majors in their book. Of course CC Zain and the Church of Light are very much related--so I was glad to know there's actually a group out there that still has a tarot with a similar system!
I like the majors in this deck and the last card in the sequence of the majors much better than the Church of Light deck, so I'm happy enough to read with it. I've never met anyone from the Church of Light, but I've heard the system is geared toward meditative study--I do not know if they use the tarot for divination or reading for others.
The very pretty minors of the Sylvia Alasia deck is more "Continental" with Egyptian decorative--that is, I thought they were similar to Lo Scarabeo's Italian Cartomancy meanings I might see in some of their earlier tarots.
I believe there are talented readers do read with mixed systems well, some don't need to know where such things come from. I do not know that my description adds clarification...hope it helped. I appreciated and still appreciate this tarot. I've got more than a few copies.
If I read with this Egyptian tarot, I read as a creative reader. I do not mix too much in. I tried to see if I could mix 'decanate astrology' or Golden Dawn meanings, and found my limitations as a reader. There are other decks that were designed for decanate astrology (Celestial) that likely work better as an integrated system.
I hope some of this helps--using a specific Egyptian deck as an explanation--and it's only my limited view.
