The extra Naturalize gives more answers against their enchantment-based engine, primarily Survival of the Fittest and Sylvan Library, which fuel their consistent creature toolbox. Thermokarst is weak since they run mostly basic Forest with only Rishadan Port, Treetop Village, Gaea's Cradle, and Wasteland as worthwhile targets, so moderating land destruction in favor of artifact/enchantment answers is better value. Swords to Plowshares is crucial against Basking Rootwalla and Wild Mongrel before they get out of hand, and Sphere of Resistance taxes their efficient curve significantly.
