Naturalize is well-positioned against Sphere of Resistance, which taxes all your spells, and can also answer Oath of Druids before it starts cheating Terravore into play. This matchup is a grindy land-based fight, so removing their Sphere of Resistance quickly restores your mana efficiency for casting Survival of the Fittest. Quirion Ranger and Wall of Roots are cut as they're too passive against a deck that will also try to out-grind you with Sylvan Library and Treetop Village. Keep Swords to Plowshares ready for any Terravore that enters off Oath of Druids.
