Some divination guide cards?
i was thinking more along the lines of fleshing out the minor arcana with some additional symbols and stuff beyond the fire diamond 0-4. Just so I could use the deck for standard 52 card games or standard tarot distribution
I'm torn between making 5-10 cards that just break the conceit of the fire diamond, or making 5-10 using related hazard symbols so everything is still real symbology
