Sworn To Darkness is a mono-black Commander precon from Commander 2014 (2014), led by Ob Nixilis of the Black Oath. Out of the box it runs 40 lands, 8 ramp pieces, 13 card-draw effects, 13 removal spells and 3 board wipes, with an average mana value of 3.85.

Measured against a typical Commander build, it's lightest on ramp, and 5 of its lands enter tapped. Its game plan leans on tokens, demon tribal and sacrifice, so the plan below favors cards that push that. The $50 plan below makes 10 swaps for $21.64.
