Using this card with "Injection Fairy Lily" allows you to deal 3200 damage to your opponent directly.
Use this card in a Rock deck, seeing that it's also a Rock-Type. Many of the most commonly used rock monsters have low ATK, so they are unlikely to destroy any of your opponent's monsters; but, many have the effect of flipping themselves face-down. You can use this card to allow 1 of those monsters to attack directly each turn, then flip itself face-down; again, with low ATK, they will not be too useful to attack more than once anyway.
Combine this card with "The Wicked Avatar". Its ATK will remain the same and it'll still be able to attack directly.
Use a monster that can battle more than once such as "Cyber Twin Dragon" to negate the ATK-reducing effect of this card.
Use "Etoile Cyber" to activate its effect by attacking directly when there is a monsters on your opponent's side of the field.
Use this card in a "Superheavy Samurai" deck. As the ace monsters of the Superheavy Samurai archetype rely on attacking using their high defense stats, the reduction in their attack will not hamper their ability to do large amounts of damage.
