A few weeks ago I received the LoS Gypsy Oracle Cards (Sibilla Della Zingara) and at first was hugely frustrated by the lack of information on combos and reading systems and card meanings for the deck. The short LWB that comes with the deck offers one spread to use and no interpretations of the cards at all. You can buy one book in English for this deck, but it is $25 on Amazon and it is a 52 page book - one page per card, with only the most basic meanings attached.
I have used Kapherus' excellent cartomancy blog as well as goldenmousedeer's blog, which are the only two I can find that give decent meanings and a few combos, as well as playing card matches for each of the cards in the deck. Also SeaQueen has written meanings out for one of the Sibella decks, and while I have cards that don't match hers in titles, still, she gives a good foundation to begin reading with them
Her blog is very informative.
I've been using daily journaling of three-card draws to give myself a familiarity with the flow of the deck and the possible meanings of the cards. I find them more nuanced and less literal than the Lenormand, perhaps because there are many more cards in the deck, and so it doesn't need to be as blunt and to the point! I am only now beginning to understand what it is trying to tell me...it's a work in progress
ETA Kalliope - thanks SO much for sharing!
