Just like it says on the tin (page title), this page will have links to the EDH Challenge of Doom™ – that is, an attempt to have one deck in each of the 27 legal colour combinations (since there are zero four-colour legends, something I hope Wizards fixes in the near future). To see the decks, click on the links below, or hover over the page link you used to get here (up there in the top right corner) and click on one of the sub-pages.
These are a work in progress; check back often!
