Gro-A-Tog has almost no creatures besides Psychatog, so Wrath of God and Powder Keg are far weaker than usual and Disenchant has no artifact or enchantment targets to hit. Meddling Mage comes in to name Gush, Counterspell, or Psychatog, disrupting their key draw engine or win condition while adding a clock they struggle to answer efficiently. Teferi's Response adds another cheap cantrip-counter that protects your lands or stops a targeted spell while drawing two cards, fitting the grindy card-advantage war. Exalted Angel provides a lifelink-adjacent clock and resilient threat that dodges Smother (mana value 6) and outraces their Psychatog damage plan. Keep Standstill, Fact or Fiction, and your counterspell suite intact since the matchup is fundamentally a battle of card advantage and efficient answers.
