WaterMonster

When a face-up Fish, Sea Serpent, or Aqua-Type monster you control is targeted for an attack: You can banish this card from your Graveyard to target the attacking monster; negate the attack, and if you do, that target loses 500 ATK until your next End Phase. You can only use the effect of "Friller Rabca" once per turn.
