Ok. I made a comment with recommendations. I made a comment expressing my dislikes. And I feel it is only fair for me to make a statement now as well:
Shortly:THANK YOU VERY MUCH STAFF FOR LISTENING TO US AND REACTING.
The bricks are gone.
Black background is gone.
Colors are much much better. Better saturation - even Frozn and Ghostown looks fine.
Commons and Uncommons are distinguishable as well as Rares and Collectors.
Mythics do feel special.
Slightly transparent ability/bonus box is really nice (Here I was wrong. Originaly I liked the opaque one, yet cards like Moukrok were just buried under that.)
In a game and shop I still have the old design which I truly loved and thought of as of a superior. Looking at it now and comparing it with this upraged new version I have to say - Well done.
This is how I imagine an upgrade, the innovation.
I am thankful you took a step back and mainly got rid of those bricks.
Today´s design as it is, is neat. Well done!
I think ideally there would be different backgrounds for each clan, because Ghostown (for example) uses a lot of light blues in the art, which makes them stand out less against the similar shade of blue of the new backgrounds. But that would be a lot of work, as there would need to be 33 (31 clans + Cr and Mt) backgrounds that are visually distinct from each other, and also do not clash with the card art for each respective clan.
