Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
During each of your End Phases, destroy this card unless you reveal 1 "Iron Core of Koa'ki Meiru" in your hand. Each time a "Koa'ki Meiru" monster on the field is destroyed during the End Phase, its owner can add 1 "Koa'ki Meiru" monster from their Deck to their hand.
