Engineered Plague naming Dog reduces Wild Mongrel to a 1/1 and shrinks a key discard outlet, while a game-by-game choice of type can also hit Elephant tokens from Call of the Herd. Infest sweeps their small early creatures like Basking Rootwalla and Wild Mongrel for -2/-2, though it will not touch a pumped Tireless Tribe that has discarded to boost toughness. Phyrexian Furnace is weak since Squee, Goblin Nabob returning from the graveyard is their only real recursion and hate-piece value here is marginal. Swords to Plowshares and Wrath of God remain your best tools against their aggressive curve of Survival of the Fittest-fetched threats and Arrogant Wurm.
