Oh, this is a solid guide!
One thing I wanted to add about the Nine of Hearts, specifically, since you mentioned the sevens - that card is traditionally called ‘The Wish Card’ in cartomancy.
When it shows up near certain cards like the Seven of Clubs, it’s supposed to signal a promise being fulfilled soon. A lot of readers treat it as the most positive card in the deck next to the Ten of Hearts. The combination of meanings is huge in this system.
