Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can target any number of your banished Fish, Sea Serpent, and Aqua-Type monsters; equip them to this card. This effect can only be used once while this card is face-up on the field. If this face-up card on the field would be destroyed, you can destroy 1 of those cards, instead. This card gains 1000 ATK while equipped with a monster(s) by this effect.
