I have it. I absolutely LOVE some of the cards, such as the Wheel of Fortune, with it's emphasis on evolutionary cycles and change.
Others, because of the blood and violence, make this a difficult deck to work with, in some respects give it a cliche, savage feel. Red of tooth and claw. And in some respects stereotypical....I'm not sure that it was intended that way, but the effort at the intensity of emotion works with some cards, but makes others into a parody of the red-man (or whatever color) savage stereotype. It's not deliberate I don't think, but definitely there....dated I think toward the earlier 1950s-1960s caveman illustrations almost...I think I'm reminded of my father's "How and Why" science books that dated to the 1950s.
In a way that's one of the reasons I like the deck, it brings back memories of going through those books that I inherited (and then stupidly got rid of). But it also makes me cringe a little, considering how much effort now goes on in academia to dispel the savagery stereotypes (Oh, I have no doubt it was there to an extent, and we're sweeping more under the rug than we really should as academics, but the deck capitalizes on it in a rather bold and blatant way).
Thank you for reminding me of it, I have to go look at it now again when I get home this evening.
There was another thread asking about it recently where I gave a slightly different take on it, I'm not going to repeat it here if I can locate the thread....the other one if I recall was more positive, but since your post seemed to likewise be a query about the negative, I thought I'd attempt an answer on that here.
I'll see if I can dig up the other thread.
