It's a design with potential, but seriously flawed.
The color scheme is OK, I guess, but a bit lifeless. And the pips - so the red pips are light red on the left, dark red on the right, while the black pips are dark red on the left, light red on the right? This would drive me blind just trying to play with them. Applying the rule of thumb "Would my old poker buddies play with this deck?", the answer is a resounding NO.
The one-way back will hurt sales.
The spot cards are also a bit confusing in terms of choices made. They appear to have either one or two of the design elements chosen for that value, but with no rhyme or reason as to why it's either one or two.
Fix the colors, make the spot cards more consistent, and you might have a good deck here.
A quote from the project home page: "A modern twist to century old tales, the Revenge desk focuses on detail." The art style is modern, but the images depicted are still from the Dark Ages.
Maybe I'm just cranky, but I don't like this deck.
