Use this with a monster that has an ability that activates in the graveyard, such as Newdoria or Mystic Tomato, because their respective effects activate regardless of who destroys it and remember that you get the effect since it was sent to your Graveyard.
Give a weak monster to your opponent and attack them to deal a lot of damage. This is really useful if your opponent is low on life points and has a monster on their side of the field with an high attack or defense you can't get through.
Give one of your monsters to your opponent and use "Breakthrough!" to destroy that monster and follow up with a series of direct attacks by your Six-Samurai monsters.
Use this card to transfer control of a high ATK monster to your opponent, then summon "Copycat" to duplicate that monster's ATK. In addition, you get back the transferred monster, giving you two high ATK monsters.
Use Kunoichi to have your opponent discard 1 card.
