Gro-A-Tog is another counterspell-and-card-draw deck, so proactive Duress strips a Counterspell, Foil, or their own Duress before you commit your key spells, buying a clean window to resolve Survival of the Fittest or Hermit Druid. Swords to Plowshares answers their Psychatog before it grows into a lethal threat off their own graveyard. Cut Elvish Spirit Guide, Squee, and Krosan Reclamation since they're too slow and your graveyard resources are better spent on your own combo than incidental value. Play around Sickening Dreams and their Smother/Annul package by not overcommitting your hand and holding a second threat in reserve.
