Hi,
Another approach which is purely "theoretical" and little intuition is to place the specific card down and draw 3 cards to establish the meaning.
I did this but used the different suit and the majors seperate to see what the card's significance would be.
example:
Ace of Cups.
I drew 3 pentacle cards, and got the "financial" value of the Ace,
then 3 other Cup cards,
Swords,
Wands and Majors the same.
In some instances I really had to think very hard to derive something simplistic, but it helped, not saying it worked!

But, it was fun to do!
Blessed be.
