Mono-Green Eldrazi ramps hard via Eldrazi Temple and Ugin's Labyrinth into huge threats like Emrakul, Ulamog, and Ugin, Eye of the Storms, so speed and disruption matter more than incremental value; Claim the Firstborn can steal an early Fanatic of Rhonas or Disciple of Freyalise mana creature to slow their ramp and add pressure. Cool but Rude provides a fast, resilient clock to close the game before their top-end threats land. Vexing Bauble has limited targets here since their spells cost mana, but still catches any free effects. Ox of Agonas is cut as too slow against a deck that can otherwise bury us with card advantage and huge bodies.
