Can be used when your Life points are at least 1000 less than the opponent's. All monsters in the opponent's Graveyard changes to Skull Servants (Zombie / DARK / Level 1 / ATK: 300 / DEF: 200). This skill can only be used once per turn.
This skill becomes viable from the previous Yami Bakura event. It will be useful against any deck that affects Graveyard, such as the Gravekeepers Deck. But due to the limitation of its' uses, it's still not recommended for ranked games.
