I've got an Olivia Mobilized deck with a Falkenrath Gorger as one of the main pieces. Gorger makes all vampires in your library have madness, with the cost being their normal mana cost. Tons of shenanigans to be had. Other than the madness creatures, I put in a bunch of burn spells with madness, like fiery temper, Avacyn's judgement, etc. Most of the deck is either a discard outlet, or a madness spell.
