Ob Nixilis of the Black Oath

Description

Ob Nixilis of the Black Oath (C14-27) is a legendary Planeswalker card from Commander 2014 that is also permitted to be your commander. His +2 drains each opponent for 1 life while gaining you that life, his −2 creates a 5/5 flying Demon at the cost of 2 life, and his −8 grants an emblem that lets you pay {1}{B} and sacrifice creatures to draw cards and gain life equal to their power. As a mono-black commander he supports a sacrifice/value strategy and provides both token generation and long-term card advantage.
