Ob Nixilis, the Adversary

Description

Ob Nixilis, the Adversary (PRM-99687) is a legendary Planeswalker card from Magic Online Promos in black and red. It has the Casualty X mechanic allowing you to sacrifice a creature with power X to create a nonlegendary token copy with starting loyalty X, and it provides +1, −2, and −7 loyalty abilities that drain life, make Devil tokens, and draw/lose life. The card functions as a midrange threat that can generate incremental advantage via life-loss and token creation while scaling with sacrificed creature power.
