Freddie... 1st question for you... have you been to Egypt? walked in the museums, the tombs, the temples? Are you trying to recreate what you saw on your travels in tarot?
That being asked... (and I have been to Egypt)... in my collection are two Los Silvana Alasia decks... Egyptian Tarot and the bling of all blings... Nefertari's Tarot (don't look at it in direct sunlight, it'll put your eyes out!
). The decks emulate pharonic art in all its glory. For that reason I love both decks. When I look at them, I'm back in the Valley of the Kings, deep in a tomb, awestruck by what I'm seeing on the walls and ceilings.
Trying to put Egyptian gods/goddesses into the RWS tarot framework is square peg/round hole. If you're looking for a one on one, ie: Seth = stormy days/tower; Ma'at = weighing of the heart/justice etc perhaps an Egyptian oracle might work better for you.
