It seems to me that part of what LB was saying, is that there's a certain repetitiveness (beyond artistic consistency) and an accompanying flatness to the BG. I could be very wrong here, though, so everyone take this with a grain of salt.
I don't know about the repetitiveness, since I don't own any MR decks, in spite of their gorgeousness and my personal attraction to the Fantastic Menagerie. The flatness, however, I tend to agree with.
There is so much potential to this deck, and from the few cards Karen, whom I do not know, has shared, there is also a lot of realized potential. It looks to me like the surface is being skimmed on what this deck can offer, and that boundaries of where it can go are still in the process of being tested.
It can be so easy to go over the top with the Victorian Gothic theme, especially since its been rehashed and even parodied nearly endlessly. The cards, so far, show great restraint - they could have easily been campy. It doesn't take much for the genre to go there.
Perhaps there is too much restraint? Not enough comfort zones being broken?
When Victorian horror first hit the market, it provided very real chills to its audience. These days, when it's become a cliche, it may be difficult to disentangle nostalgia from creepiness. These images are safe because we are already familiar with the archetypes presented.
To a Victorian, the image of a woman dancing with skeletons would have been a vastly different experience than to any one of us. What Karen and Alex are doing looks like a distinct attempt to recreate the momentum such a picture might've had for its original audience, which is a monumental task IMO.
I think this "flatness" I'm mentioning has a lot to do with the familiarity with the genre a lot of fans of this deck have. For some, it's pitch perfect. Others, like me, will want the envelope pushed as far as it can go.
Of course, this deck isn't copletely finalized. As such, it shouldn't be held up to the stadards of a finished product. I believe she already mentioned that is still a work in progress.
That being said, these are all points of discussion.
