[IaWA] Making new Oracles: how?

[Klaus_Welten]

I was going to write down a set of Oracles inspired by The Rose of Versailles, but I ask just to be sure: is there a criterium for writing down the single cards? How do you divide people, facts, etc. between Hearts, Spades and so on? Are figures and aces supposed to carry a specific theme?
Thanks for your attention.

In the four oracles in the book, there's no system for suit or rank. I just assigned items to cards at random.
