Sultai Aluren wants to resolve Show and Tell into Omniscience or cheat Atraxa, Grand Unifier into play, so single-target removal like Fatal Push and Snuff Out (and even Drown in the Loch, which checks graveyard size for its modes) is often too narrow or too slow against a 7/7 or a free-casting engine. Snuff Out can't target black creatures at all, which rules out Atraxa and Acererak the Archlich. Trimming those slots makes room for graveyard disruption and a fast clock. Surgical Extraction strips copies of Aluren or Show and Tell out of their graveyard, hand and library once one hits their graveyard, disrupting their most consistent lines. Dauthi Voidwalker is an evasive clock that their creatures can't block, and it exiles cards heading to their graveyard, denying them any graveyard value. Unlicensed Hearse adds another way to proactively strip their graveyard (relevant as their cantrips and Show and Tell land there) while growing into a real threat. Keep Orcish Bowmasters, Thoughtseize, Force of Will, and the core draw/disruption package intact since disrupting Show and Tell/Aluren and punishing their card draw remains the primary win condition.
