@herself A belated wow, great, love it!
Also, Tarot and Oulipo in the same essay? You are my people! I’ve been a lifelong advocate for chance operations as part of the creative process; with only a little modification, I think a lot of what you say is applicable to other genres, too, especially poetry.
My favorite decks are the Rider, the Marseilles, and the quirky Morgan’s Tarot, which I’ve loved ever since encountering it in the mid-80s. Eno’s Oblique Strategies is another excellent tool to shake things up.
