WUBG plays Oath of Druids and Sphere of Resistance, both of which Naturalize and Uktabi Orangutan can profitably destroy — Sphere of Resistance in particular taxes your mana-hungry Survival activations and Hermit Druid plan heavily. Cut Elvish Spirit Guide and Squee, Goblin Nabob for the extra artifact/enchantment answers since neither helps you fight through a resolved Sphere or Oath. Watch for Terravore growing large off both graveyards and be mindful that Wasteland and Rishadan Port can strand your fixing lands, so sequence your City of Brass and Gemstone Mine plays carefully. Your Birds of Paradise and Wall of Roots help you play through the Sphere tax better than most decks, so prioritize deploying them early.
