Feast of Flesh is an aggro/control black/red intro pack with a focus on creature removal.

“ Phyrexians are among the most brutal, vicious monstrosities ever seen, and now that their victory is at hand, there's no stopping the carnage. Of course, as long as you're playing this deck, that's just the way you want it!
The primary goal of the deck is to annihilate every creature your opponent casts. Spells like Geth's Verdict, Go for the Throat, and Parasitic Implant mow down opposing creatures, often while providing an extra bonus in the process. Even your creatures get into the act: Blisterstick Shaman and Tormentor Exarch can each take out a creature when they show up on the battlefield.

In fact, not even your own creatures are safe! Casting Artillerize or Fling means you'll sacrifice one of your creatures to wipe one of your opponent's creatures—presumably a better one—off the map. This is a war of attrition, and as long as you keep all opposing forces nice and dead, any attack you can muster is sure to go the distance. Or you can just keep the battlefield clear, knowing that eventually Chancellor of the Dross or Shrine of Burning Rage will show up to finish things off.

Some other New Phyrexia cards that would fit right into the deck include Dismember, which is yet another way to efficiently axe a creature, and Sheoldred, Whispering One. This 6/6 Praetor lets you continually reclaim your dead creatures from your graveyard so they're ready to be sacrificed for the cause once again, while also forcing your opponents to sacrifice their own creatures turn after turn.
