My favorite and most pimped out as of yet Commander deck: Sek'Kuar, Deathkeeper.

If you enjoy Jund Midrange-y kind of decks, this one might be for you. It can run pretty smoothly without the commander out, but is made only better when Sek'Kuar is on the field. No infinite combos, just pure tempo swings.
