Maiden of the Aqua
Card effect (current official text)As long as this card remains face-up on the field, the field is treated as "Umi" (however there is no increasing or decreasing of ATK/DEF due to "Umi"'s effect). If there is an active Field Spell Card on the field, this effect is not applied.
Rulings
- The effect of Maiden of the Aqua is applying only when there is no face-up Field Spell Card on the field. When a Field Spell Card is activated after Maiden of the Aqua is Summoned, the effect of Maiden of the Aqua is negated as long as there is a face-up Field Spell Card. If the only Field Spell Card is face-down, the effect of Maiden of the Aqua is applying. If there is a face-up Field Spell Card but it is negated by Imperial Order, the effect of Maiden of the Aqua is not applying.
- If a Field Spell Card is already applying, and Maiden of the Aqua is Summoned, the existing Field Spell Card continues to function and Maiden of the Aqua’s effect is not applied until there is no face-up Field Spell Card.
- If you have Maiden of the Aqua (with her effect applying) and The Legendary Fisherman or Deepsea Warrior on your side of the field, and Dark Hole is activated, The Legendary Fisherman and Deepsea Warrior will not be destroyed.
