If you have multiple monsters on your side of the field, and you want your opponent to attack one, but not the other(s), then equip that one with "Raregold Armor", and activate both "Battle Mania" and "Final Attack Orders" during your opponent's next turn. Then, they will be forced to attack the monster that you equipped with "Raregold Armor".
Equip this card to a monster while you have "Black Veloci" and/or "Steamroid" on the field, so it won't lose 500 ATK because it won't be able to be attacked as long as the equipped monster is on the field.
Equip this card to an "Earthbound Immortal". The "Earthbound Immortal's" effect will prevent it from being selected as an attack target, but this card prevents your opponent from selecting any other monster you control as an attack target, resulting in your opponent being unable attack any of your monsters.
