Whenever an opponent searches their library, that player sacrifices a creature of their choice and loses 10 life.
Whenever another creature dies, put a +1/+1 counter on Ob Nixilis.
Ob Nixilis is a mono-black punisher/grindy beats commander. You leverage his fetch-land tax to drain opponents and his death-trigger growth to become an evasive 9-power threat, while a sacrifice/aristocrats and forced-tutor shell turns the board into fuel. You win by clocking with a flying, trampling beater backed by recursion, removal, and resource denial.
Punishes the many tutors and fetchlands common in higher-power pods (10 life and a sacrifice each search).
Snowballs huge with flying and trample, quickly becoming a one- or two-hit commander.
Mono-black gives access to the best tutors, removal, and recursion in the format.
Synergizes naturally with aristocrats and forced-sacrifice effects since any creature death grows him.
His punish trigger only fires on opponent searches, which is inconsistent and table-dependent.
Six mana and no built-in protection make him easy removal bait and prone to commander tax.
Mono-black struggles with persistent enchantments, flyers, and lacks card-draw efficiency outside of life payment.
No evasion versus chump-blockers without trample being respected, and edict effects can be turned against you too.
