WUBG leans on Sphere of Resistance to tax your spells and Sylvan Library to fuel card advantage, both of which Naturalize answers cleanly and efficiently. Daze and Mana Leak lose value once Sphere of Resistance is in play since the extra generic cost makes them harder to cast on curve, so trimming them for proactive artifact and enchantment removal is correct. Keep Wasteland in to attack their utility lands like Treetop Village and Mishra's Factory, since this deck is light on basics. Use Survival of the Fittest to find Gilded Drake against Terravore, which can otherwise grow into an unbeatable threat as lands pile into graveyards.
