Basic strat:
Straightforward attack with threats that are all either recurring, evasive or add value. As many as possible are must-answers, to reduce time to gain field presence.
1) Cheap, reuseable critters with built-in recursion. Bloodsoaked Champions & Flamewake Phoenix
2) Accelerated beef - in the form of Generator Servant

Underworld Cerberus
. worst-case scenario, the Servant is a 2/1 for 1R that will keep the opponent guessing. Middle case is they use removal on it, and best is it gets its desired effect of turn 3 hasty Cerberus
3) must answer clocks on curve: Master of Feasts DOES give them an extra card on turn 4, but it does not give them extra mana to cast them. Also, I've found little difficulty tapping four black and sacrificing one Generator Servant to haste out two Masters on turn four. Stormbreath Dragon is a sub-optimal target for Generator Servant play, since it already has haste - but it is evasive and has protection from several of the key removal cards.
One maindeck Tymaret, the Murder King because it is just such a nice interaction if there is a stall to late game.
I've been looking for Underworld Cerberus to have a home for a while and I think this might be it.
The Hound's downside, bringing the opponents graveyard back to life also, is brought under control both by having both nasty threats and by maindeck Agents of Erebos - expensive for a 2/2, but by exiling the opponents graveyard on turn 3/4, you are set for a win/win trade if they kill the Cerberus.
Previous cards that were in deck but have been pulled out: Hammer of PurphorosCollateral Damage (in favor of Bile Blight)Scuttling Doom Engine - too much / too little
Many of the exile effects are white, and mainboard Stormbreaths make those hard to cast - as well as hold off any stampeding Siege Rhinos.
Currently only running one
Shaman of the Great Hunt
both because of lack of more copies in-hand, and because it is too tempting to try to throw in mana to activate it's draw ability.
Other maybe's Outpost Siege - I want it to fit, but it doesn't quite do the trick.
