Gro-a-tog is a mono-blue-black tempo-control deck with no red spells or permanents, so Blue Elemental Blast and Hydroblast stay in the sideboard, and it runs no artifacts or enchantments worth a Naturalize. This matchup comes down to the Daze and Mana Leak war and who assembles their engine faster, so the maindeck configuration is already well-suited and needs no changes. Use Survival of the Fittest to find Gilded Drake as a proactive answer to a resolved Psychatog before it grows out of range. Sequence Careful Study and Frantic Search carefully to avoid discarding your own answers into a deck that can punish you with Duress and Smother.
