BR - Maddening Hellbent

Maddening Hellbent is a deck that takes profit of Madness and Hellbent, two abilities that complement each other to great extent, offering the player with some interesting and aggressive options.
Volrath's Dungeon and Anvil of Bogardan are there to both help achieve the goal and to disrupt the opponent's gameplay, while Rix Maadi and Gathan Raiders are more discarding outlet.
I'm not sure if with the Anvil I still should keep one Lim-Dul's Paladin.
This deck needs some deep testing.

The Call of the Netherworld is worthy since most of my creatures are black. And Brink of Madness is great! It isn't a hellbent card but it fits the theme and goes great with the Barghest for some added damage.
