This is a near-mirror matchup built around the same Survival of the Fittest and Wirewood Symbiote engine, so disrupting their mana acceleration and engine pieces is the priority. Pyroclasm is the critical sideboard card here, sweeping their mana elves, Wirewood Symbiotes, and Deranged Hermit Squirrel tokens while leaving your larger creatures intact. Naturalize gives you efficient answers to their Survival of the Fittest and Gaea's Cradle, dismantling the tutoring and mana engine that both decks rely on. Tormod's Crypt removes Anger and Genesis from their graveyard, stopping haste activation and recursive creature value. Squee's Revenge has no Squee to target in your deck and is effectively dead, while Orcish Settlers, Wall of Roots, and the slower utility creatures contribute too little in a race defined by who lands and protects their Survival first.
