Tormod's Crypt is strong against The Rock's graveyard synergies, denying Recurring Nightmare and Volrath's Stronghold targets and preventing Haunting Echoes from being a one-sided disaster later. The extra Nantuko Vigilante gives you a morph creature that can destroy their Pernicious Deed before it blows up your board, which is their best answer to your wide Elf strategy. Anger and Squee are weak here since The Rock's removal-heavy plan (Chainer's Edict, Smother) picks off small creatures easily, and Skyshroud Poacher is replaceable with more impactful disruption. Keep your Survival of the Fittest package as your primary way to out-value their grindy removal suite.
