Ob Nixilis of the Black Oath

Description

Ob Nixilis of the Black Oath (PZ1-45) is a legendary planeswalker card from the Legendary Cube Prize Pack that is black and costs five mana. Its +2 drains life from each opponent while the −2 creates a 5/5 flying Demon token at the cost of 2 life, and its −8 grants an emblem enabling repeated sacrifice-for-life-and-card-draw based on sacrificed creature power. The card is also explicitly permitted as a commander, which gives it a distinct role in singleton commander decks.
