The Core Set Super Cube
http://mtgadventures.blogspot.com/2015/05/the-core-set-super-cube.html
I have gone back and forth about including Tenth Edition, and I have decided that it must be in. Therefore, the cube as planned is Tenth Edition, M10, M11, M12, M13, M14, M15, and Origins. That's eight core sets. That is a ton of cards. I wonder how many decks that match specific archetypes can be built when we limit ourselves to just these cards.
May 2020 update:
I am finally working on this cube. Add M19, M20, and soon, M21.
Here are a few 10th Edition posts. I will add more links to this general post as I make more progress.
