• Use "Koa'ki Meiru Urnight" to Special Summon a "Koa'ki Meiru" monster. Let the Summoned monster die so you can search a Beast-Warrior to maintain Urnight the next turn.
  • In the worst case scenario, activate this card if you control a "Koa'ki Meiru" you can't keep on the field, even if you don't have the "Iron Core of Koa'ki Meiru". Since both effects belong to you, choose to destroy the monster first, trading 2 dead cards for any "Koa'ki Meiru" in your Deck.
