Lands relies on recursive value engines like Life from the Loam and the Dark Depths plus Thespian's Stage combo for Marit Lage as a key win condition; Surgical Extraction, castable for 2 life, can exile Dark Depths itself or a copy of Thespian's Stage once one hits the graveyard, cutting off their combo redundancy. Spell Pierce is weak since Lands can often play around a small tax given their abundant mana from Urza's Saga and Mox Diamond. Our plan otherwise relies on fetches to dodge their Wasteland while pressuring with Stoneforge Mystic threats before they assemble their lock pieces, so we keep changes minimal and don't cut any lands.
