Or, by putting one core from a "The Grandwalker Amaterasu" you control to this Spirit, during this battle, effects of opposing Spirits/Ultimates can't activate, and return an opposing Spirit/Ultimate to the deckbottom. This effect can't be prevented by opposing effects. When you've done so, this Spirit refreshes.
