结界
每当你施放人鱼咒语时,派出一个1/1蓝色,具辟邪异能的人鱼衍生生物。(具辟邪异能的生物不能成为由对手操控之咒语或异能的目标。)
If an effect refers to a "[subtype] spell" or "[subtype] card," it refers only to a spell or card that has that subtype. For example, March of the Drowned is a card that benefits Pirates and features Pirates in its illustration, but it isn't a Pirate card.
