Description

Ob Nixilis of the Black Oath (CMM 517, etched foil) is a legendary Planeswalker card from Commander Masters with a five-mana black cost. Its abilities drain small amounts of life for you and opponents, can create a 5/5 flying Demon at the cost of life, and its ultimate grants an emblem that converts sacrificed creature power into card draw and life. The card includes the explicit rule allowing it to be used as a commander, making it a thematic option for mono-black commander decks.
