I like the idea, but I'm not sure about the execution. Some of the guidelines look very dark and heavy. Just looking at the example on the main kickstarter image, the art gets a bit lost in the grid.
Secondly, it looks like the binding is like that of a notepad. I'm not sure what it's called exactly, but it's not a very permanent binding and in most cases you tear off each sheet as you move on to the next. For this sort of notebook, I'd want a more permanent binding to keep an entire deck bound together in one place. Actually, it would almost be best in a binder sort of thing so you could remove a sheet to refer to it as you worked on another, but then bind it all back together. That would also give you the option of changing the order of sheets to trace certain elements.
