Your opponent cannot target WATER monsters for attacks or with card effects, except this card. WATER monsters you control gain 200 ATK for each Xyz Material attached to this card. If this card has "Abyss Dweller" as an Xyz Material, it gains this effect.
● Once per turn, during either player's turn, when a card effect is activated in your opponent's Graveyard: Negate that effect and attach that card to this card as an Xyz Material. When this card on the field is destroyed: You can target a number of cards on your opponent's side of the field, up to the number of Xyz Materials that were attached to this card; send those targets to the Graveyard.
