Elesh Norn, Grand Cenobiteremoval$19.08A much stronger asymmetric anthem-style effect that shrinks opposing creatures while boosting yours. It fills a similar board-warping role, though at a much higher power level.
Engineered Plagueremoval$8.04Another global -1/-1 effect that can function as a tribal hate piece or creature sweeper. It is narrower than Night of Souls' Betrayal but often plays a very similar game against token or tribal decks.
Virulent PlagueremovalBudget$0.13Provides a global -2/-2 style answer to tokens by shrinking all creature tokens. It is not as universal as -1/-1 to all creatures, but it serves a similar anti-creature static-hate role.
The Meathook Massacreremoval$26.44A black enchantment that weakens opposing boards and later acts as a scalable sweeper and drain engine. It overlaps in being a persistent board-control enchantment, though it does much more.
Black Sun's ZenithremovalBudget$0.35A scalable black sweeper that gives creatures -X/-X until end of turn. It is a one-shot effect rather than a static one, but it fills the same creature-debuff/removal niche.
Toxic Delugeremoval$7.62One of black's best sweepers, shrinking all creatures by a chosen amount at very efficient cost. It is not permanent, but it answers boards in a way similar to a global stat-reduction effect.
Cloak and Daggerutility$1.23A cheap black equipment that can help small creatures survive opposing -1/-1 effects and combat. It is more of a support card than a direct equivalent, but it fits black's low-end board interaction space.
Drown in Ichorremoval$0.99A black instant that gives a creature -4/-4 and can proliferate, functioning as efficient targeted removal. It is narrower than a global enchantment, but it aligns with black's creature-shrinking removal theme.
