虽然洞窟爬虫万物皆能食，植物岩石全不忌，但它们还是更喜欢鲜肉。

Primordial Gnawer

When Primordial Gnawer dies, discover 3. (Exile cards from the top of your library until you exile a nonland card with mana value 3 or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)

当原初啮骨虫死去时，倾探3。（从你的牌库顶开始放逐牌，直到放逐一张法术力值等于或小于3的非地牌为止。施放之且不需支付其法术力费用，或将之置于你手上。将其余的牌以随机顺序置于你牌库底。）
