OCG Rulings
- If you have multiple copies of this card, you can activate the "Add 1 "Koa'ki Meiru" card from your Deck to your hand, except "Diamond Core of Koa'ki Meiru"." effect of each copy.[1]
- The "this turn, "Koa'ki Meiru" monsters you control cannot be destroyed." effect starts a Chain Link. (Banishing this card from the Graveyard is a cost to activate this effect.)[1]
- The "this turn, "Koa'ki Meiru" monsters you control cannot be destroyed." effect is also applied to monsters that appear on the field after this effect has been activated.[1]
- "Koa'ki Meiru" monsters are not just protected from being destroyed by battle or card effects, but also from being destroyed by their maintenance cost ("During each of your End Phases, destroy this card unless").[1]
- The "this turn, "Koa'ki Meiru" monsters you control cannot be destroyed." effect stops applying at the end of the turn. (This effect is applied until the the end of the turn, not until the End Phase.)[1]
