I love this deck so much!
For me it works best for spiritual, shadow work, and inner child questions. It's not very everyday practical, for me. But it reads very clear for me, and sometimes in a shocking way, giving me cards that really describe my feelings towards my mother and my inner child etc.
I think if you dig into the images, really study the cards, then you can make a pretty clear RWS connection, in my opinion. BUT... Just like most other people I do tend to read this more oracle style. I connect numerology and elements with the image to a certain extent, but I stay away from thinking too much about "traditional RWS meanings".
Most of the time I just look at the image and see what it tells me. And get your energy into it, shuffle shuffle!
I'd advice you to dig into this deck, maybe for shadow work if that seems interesting to you. I used it for a week or more, exclusively, for this deck challenge on YouTube:

So give it a chance, keep an open mind, but you know, sometimes a deck just isn't meant for you and then it might be time to trade it.
Good luck!
