• Use with "Book of Eclipse" to keep control of all the monsters you take from your opponent, as if the monster are flipped face down, they will not return to the opponent, even if they no longer have A-counters on them, and "Mass Hypnosis" is destroyed at the end of the turn.
  • Use "Imperial Custom" so that this card doesn't destroy itself, and the monsters stay on your side of the field.
  • Use your opponent's monsters as costs for cards like "Mystik Wok" or "Crop Circles" before they return to your opponent.
  • Use "Cosmic Fortress Gol'gar"'s effect to bounce this card back to your hand to avoid losing it, set it back almost immediately to activate it the next turn before your opponent attacks.
