Mono-Green Eldrazi relies heavily on Fight Rigging, an enchantment that hides away a free spell and grows creatures, plus various colorless lands like Eldrazi Temple and Ugin's Labyrinth for ramp, so Force of Vigor is excellent at destroying Fight Rigging for free before it can cheat out a huge threat. Endurance's evoke resets their graveyard against Emrakul, the Promised End's cost reduction and denies value from Malevolent Rumble or Green Sun's Zenith looping through the yard, while also serving as a solid blocker against Fanatic of Rhonas or Slumbering Trudge. We cut the small-target removal (Dead // Gone, Sink into Stupor) since their real threats are huge (Emrakul at 13/13, Ulamog, Drowner of Truth) and untouched by 2 damage or bounce that just delays them a turn. Force of Negation remains vital to stop Emrakul, the Promised End or Ugin, Eye of the Storms from resolving.
