Eldrazi Tron ramps into colorless threats and artifacts like Karn, the Great Creator, Ugin, Eye of the Storms, and Chalice of the Void, making Nature's Claim a great tool to strip away Chalice of the Void or Trinisphere before they lock you out of casting spells. Pact of Negation is dangerous here since Chalice of the Void set at zero counters it or Trinisphere taxes its casting cost, so cut it in favor of proactive artifact removal. Consign to Memory is a maindeck star in this matchup since nearly all of their threats and disruption (Devourer of Destiny, Kozilek's Command, Ugin's cast trigger, Karn) are colorless.
