Eldrazi Tron ramps through Urza's Mine/Power Plant/Tower and Eldrazi Temple into Karn, the Great Creator, Ugin, Eye of the Storms, and giant Eldrazi; Brotherhood's End's artifact-destruction mode sweeps Expedition Map, Talisman of Resilience, and Giant's Boulder, denying their mana acceleration and artifact value. Boseiju, Who Endures can proactively destroy a nonbasic land (like Urza's Tower or Ugin's Labyrinth) to disrupt their mana base, swapped in as a land replacing the Mountain so your land count stays intact. Cut one Lightning Bolt since their threats (Devourer of Destiny, Ulamog) are far too large for 3 damage, and trim the Stomping Ground since Boseiju covers the land slot while still producing green mana you rarely need. Leyline Binding and Teferi, Time Raveler remain crucial for answering and disrupting their planeswalkers and big Eldrazi.
