Marcella Kroll’s decks are my favorite right now. Nature Nurture because it is fairly small and portable (smaller than a deck of cards, a little thicker though). I also love her Sacred Symbols deck for the simplicity of color scheme and imagery. I get very clear meanings and images from it.
I second Marcella’s Sacred Symbols deck! I also like the Wild Unknowns Archetype deck (but be warned, it’s a no bullshit no sugar coating reading with that one). I also use my Flowers of the Night Oracle fairly regularly too!
