Lands relies on key nonartifact lands like Dark Depths, The Tabernacle at Pendrell Vale, and Urza's Saga for their engine, so Liquimetal Coating can turn one of their problematic lands into an artifact, opening it up to our own artifact-based removal and Karn interactions. Tormod's Crypt is a low-cost way to disrupt Life from the Loam's dredge recursion engine that fuels their land-based value loops. Force of Negation is weak here since Lands plays very few noncreature spells worth countering, and Sink into Stupor's bounce mode has few profitable targets against mostly lands, so both are trimmed slightly for more proactive disruption.
