Meren of Clan Nel Toth has been one of the defining graveyard commanders for years, regularly appearing atop popularity charts. She rewards you for sacrificing creatures by turning every end step into a reanimation or regrowth, which pairs perfectly with classic aristocrats shells. Online primers describe her as a value machine that can be built from casual to very oppressive, depending on the surrounding meta. Her combination of inevitability, resilience, and straightforward gameplay keeps Meren a go-to choice for Golgari graveyard fans.
