Fade from History destroys Agatha's Soul Cauldron and Leyline of Abundance, cutting off their mana engine and counter-synergy package, while Endurance puts their graveyard on the bottom of their library, disrupting Fiend Artisan and any recursive value they generate. Dismember struggles to matter since their combo doesn't rely on a single creature dying to -5/-5, and Sink into Stupor only buys a turn against a deck that reassembles its mana engine quickly. Keep Force of Negation and Subtlety as your key interaction to counter Devoted Druid, Green Sun's Zenith, or Craterhoof Behemoth before they combo off. Force of Vigor is also a reasonable inclusion if you want more redundant artifact/enchantment answers, but Fade from History's sorcery-speed bear generation is a fine floor here.
