Anyone else taking on, or has completed, the Chromatic Challenge for EDH?
The concept has been around for a while but for those that don't know it's essentially the idea of building a deck of each possible color combination to include colorless, so all in all 32 decks.
I'm currently at 10 complete with 5 more I'm working on (a few of which are just reassembling and updating retired decks). It's a blast since I enjoying building and retooling decks.
