Sanctifier en-Vec exiles black and red cards from graveyards as they hit it, which disrupts Goryo's Vengeance targets like Atraxa, Grand Unifier and Griselbrand sitting in the graveyard, while also granting protection from black to dodge Fatal Push and Thoughtseize discard is irrelevant to protection but the exile effect matters most here. Teferi, Time Raveler stops them from flashing in Solitude or Force of Negation on our turn and can bounce a reanimated threat while restricting them to sorcery-speed interaction. We cut slow artifact filler (Forge Anew, Meticulous Archive, Ornithopter, Paradise Mantle) since this matchup is about disrupting their graveyard plan and playing around interaction, not grinding with extra bodies.
