Gro-a-Tog's clock is built on countering our key spells and growing Psychatog with graveyard fuel, so Duress strips their Counterspell, Circular Logic, or Mana Leak before they can protect their plan. Smother answers their Psychatog while it's still small and cheap to kill, since Psychatog is mana value 3 and dies before they pump it with discard or graveyard exile. Mulch is cut because it fills their Psychatog's graveyard-based pump fuel indirectly less than it helps us, and we'd rather have proactive disruption against their countermagic-heavy shell; Unearth is weak since they run almost no early creatures worth reanimating. Keep Wasteland active against their Polluted Delta/Underground River manabase to slow their double-blue requirements for Counterspell and Foil-adjacent effects.
