Copy of: Phyrexian Obliteration (mono black discard control) (Modern)

This deck was build around the Phyrexian Obliterator and the main focus of the deck is discard and board control. The ideal way to begin the game is to play Despise and Wrench Mind in the first turns, followed by a Gifted Aetherborn to gain control of the game from the beginning. In the midgame you will have card advantage by playing the entchantments Waste Not and Underworld Connections. The Sangromancer will keep you alive for a long time and once the Phyrexian Obliterator or Sheoldred, Whispering One are on the field, you should be able to win pretty easily. Using Surgical Extraction will give you the ultimate control of your opponents game and some removals like Hero's Downfall will make it easier to hit the opponent. Even in case of losing an important creature you can keep one Mortuary Mire in Hand to bring it back from your graveyard.
In summary this deck contains a lot of typical black elements and is fun to play. It is not the best possible black control deck but it is reliable.

I am always open for discussion or questions if interested.

Card choices and sideboard:
I did not use Black Rite, even if it can be useful in mono black. The reason is that it generates card disadvantage and this deck wants to achieve the opposite by gaining card advantage. You do not need to speed this up due to the lifepoints you can earn with Sangromancer and Lifelink Effects on creatures and because of the control elements that are contained. I know there are a lot of variants with Black Rite in there and they are also doing well.
The other cards in the sidebord are situation depending and will change the number of certain spells if neccessary.
Especially against fast creature pressure in aggro decks you can fasten up your removals by using Disfigure and bale blight against token decks.
