Add 1 "Koa'ki Meiru" card from your Deck to your hand, except "Diamond Core of Koa'ki Meiru". You can banish this card from your Graveyard; this turn, "Koa'ki Meiru" monsters you control cannot be destroyed.
This card is sick. Searches the Iron Core and the Koa'ki Meiru guys without once per turn restriction and protects from all destruction including the maintenance costs.
Can be recycled by Crusader for further searching.
