結界
每當你施放人魚咒語時,派出一個1/1藍色,具辟邪異能的人魚衍生生物。(具辟邪異能的生物不能成為由對手操控之咒語或異能的目標。)
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.
