Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card is activated: You can add 1 of your "Icejade" monsters that is banished or in your GY to your hand. Once per turn, if a monster(s) is Normal or Special Summoned (except during the Damage Step): You can target 1 WATER monster you control; that monster, along with any face-up monsters your opponent currently controls, loses ATK equal to the targeted monster's original ATK, until the end of this turn. You can only activate 1 "Icejade Cenote Enion Cradle" per turn.
