WUBG is a graveyard-recursion deck that leans on Bloodghast and Prized Amalgam returning from the graveyard. Bloodghast comes back whenever they play a land, and Prized Amalgam comes back when a creature enters from their graveyard, such as a recurring Bloodghast. Narcomoeba is different: it doesn't recur from the graveyard. It enters the battlefield only when it is milled from the library, so graveyard hate doesn't stop it. Unlicensed Hearse exiles up to two cards from a graveyard each time it taps, which disrupts Bloodghast and Prized Amalgam. Necromentia can name Bloodghast, Prized Amalgam, or even Narcomoeba and exile every copy from their hand, graveyard, and library at once. Naming Narcomoeba is the way to stop it from being milled in. Tear Asunder has few targets here unless kicked (unkicked, it mostly hits Founding the Third Path), and Culling Ritual only temporarily answers Bloodghast, which returns on landfall, while also destroying our own cheap permanents like Badgermole Cub. We cut those two plus Restless Cottage to make room for the three new cards.
