Erratic Mutation 飘摇异变
{2}{U}
Choose target creature. Reveal cards from the top of your library until you reveal a nonland card. That creature gets +X/-X until end of turn, where X is that card's mana value. Put all cards revealed this way on the bottom of your library in any order.
选择目标生物。从你的牌库顶开始展示牌，直到展示出一张非地牌为止。该生物得+X/-X直到回合结束，X为该牌的总法术力费用。将所有以此法展示的牌以任意顺序置于你的牌库底。

你是在结算飘摇异变的过程中展示牌并令该生物得+X/-X。在这两个动作之间不会发生任何事情，也没有牌手能有所行动。
You reveal cards and the creature gets +X/-X all while Erratic Mutation is resolving. Nothing can happen in between, and no player can take actions.
