I just finished building a new commander cube. If you're interested in drafting something fresh and new, you can check it out here:

It started when Osgir, the Reconstructor and Prosper, Tome-Bound made me reconsider the archetypes I support in this cube. I started a new cube to keep track of cards that would I would add for them, and that turned into looking at all the guilds with an eye towards artifacts.

The general archetypes look like this:

• Azorius: self-mill
• Dimir: clues
• Rakdos: casting cards from exile/treasures
• Gruul: landfall
• Selesnya: lifegain
• Orzhov: lifegain
• Izzet: any artifacts
• Golgari: food
• Boros: self-mill/artifact value
• Simic: clues
