Necrotic Wound⁣ - Guilds of Ravnica⁣ (Uncommon)⁣ [79]

Necrotic Wound is a black instant from Guilds of Ravnica that gives a target creature -X/-X until the end of turn, with X equal to the number of creature cards in your graveyard. This can effectively remove key threats from the board, especially in decks that utilise the graveyard, and the exile effect prevents any resurrection tricks. It's especially fitting in Golgari strategies that focus on creature recursion and managing your opponent's board presence.
