- If there is a monster equipped with Ring of Magnetism on the opponent’s side of the field, if your monsters are going to attack they must attack the equipped monster. Even Toon Monsters, Inaba White Rabbit, and monsters like Jinzo #7 and Queen’s Double that can normally Attack Directly must attack the equipped monster.
- If you have two or more monsters on your side of the field equipped with your Ring of Magnetism cards, you choose which monster will be attacked.
