After thinking it over, I realized I don't yet have a go-to oracle for any sort of real readings. All my oracles with the exception of Madame Endora seem better suited to meditative work. The Madame, well, I truly adore her, but I've yet to find her useful for anything other than working with fiction writing. From a meditative/introspective standpoint, I tend to reach for the Druid Animal and Plant Oracles (usually in app form), or the Enchanted Map.
For Tarot, my default go-to is Shadowscapes. But I also find I can take quite a bit of what I read on over to the Tyldwick and get excellent results.
