Standard mono black control.

Basic black control deck with Sanguine/Exquiste combo for infinite. Every creature has a way to trigger the loop aside from descration demon. Mostly just a creature control deck.

Been playing it a lot on MTGO. Have been very successful against most "meta" decks in standard events, but am really struggling with mono colored decks (mono green aggro, mono red young pyro/tokens). Also have struggled against Aetherling if it hits the board(aside from removing it if they tap all out).
