Leyline of the Void is excellent here, cutting off Nethergoyf's growth, its Escape cast, Moonshadow's counter removal, Street Wraith cycling fuel, and Detective's Phoenix's Collect evidence/bestow-from-graveyard line. Toxic Deluge gives a sweeper against their small creature suite (Stitcher's Supplier, Fear of Missing Out, Nethergoyf) when they go wide. Spell Pierce is poor against a deck full of cheap creatures and removal that doesn't mind paying 2. Theorix Charm's counter mode is weak against their low curve, though we keep enough interaction via Fatal Push and Counterspell.
