Show the difference between any version of a cube.

[jaredcurtis]

What would you like to be able to do?
I want to be able to generate the difference between any 2 versions of a Cube. My specific use case is to update my MTGO Vintage cube to the latest version without reading each release to determine the differences.

Describe how you would use the feature
I want to select a version of a cube for the history page as my starting point. Then select any other point on the history timeline as the endpoint. With those parameters, I want CubeCobra to show me the cards to add and remove to bring my version in sync with the target version.
