Damping Sphere is excellent against their Urza lands' burst mana, slowing their path to The One Ring, Karn, the Great Creator, or Ugin, Eye of the Storms by capping how much mana their big lands produce. Collector Ouphe turns off Grim Monolith and stops any Expedition Map or artifact-based value they lean on, while offering a body to pressure their low creature count. Elvish Reclaimer and Scythecat Cub are too slow against a prison-ramp deck that can lock us out with Trinisphere-style effects from the sideboard. Wasteland remains a premier answer to their Urza-land-based manabase.
