Naturalize is premium removal here, picking off Sylvan Library before it snowballs their card advantage or hitting Mox Diamond to slow their acceleration. Tranquil Domain wipes all non-Aura enchantments at instant speed, letting you blow out multiple Sylvan Libraries or Seals in one shot if they resolve more than one. Their own Armageddon plan already punishes symmetrical land destruction, so cutting our copies avoids mirroring a strategy they execute better with Weathered Wayfarer to rebuild afterward. Monk Realist and Thornscape Battlemage are the weakest bodies against their efficient removal suite of Swords to Plowshares and Pyroclasm, so they step aside for the enchantment answers.
