Naturalize is a cheap, efficient answer to Survival of the Fittest, shutting off their tutoring engine for Deranged Hermit, Masticore, or Anger before it takes over the game. The slow Krosan Tuskers are cut since this matchup rewards proactive disruption over incremental card selection. Duress and Cabal Therapy should aim at Survival of the Fittest itself, and Pernicious Deed is strong against their small-creature swarm generated by Deranged Hermit tokens or Wirewood Symbiote loops.
