Force of Vigor is a free, uncounterable-by-cost answer to their Leyline Binding, taking back a locked-away threat, and can be cast for free on their turn to blow it up in response to a key attack step. Endurance resets their graveyard to strip Murktide Regent's delve fuel and flashback fuel from Ponder/Brainstorm-driven digging, while providing a relevant blocker against Phelia, Exuberant Shepherd or Murktide Regent. Shang-Chi, extra Quirion Rangers, and Grist are lower-priority against a controlling deck full of cheap countermagic like Force of Will and removal like Swords to Plowshares, so we trim to more efficient, resilient threats and disruption. Try to play around Force of Negation and Daze by sequencing efficiently and using Allosaurus Shepherd to push green spells through.
