Set this card and use "Book of Taiyou" to put this card in your opponent's deck. Then use "Jade Insect Whistle" to put this card on top of your opponent's deck, so he/she will draw it next turn. After this, you have a few options:
Combine this with "Insect Barrier" to prevent all your opponent's monsters from attacking.
Combine this with "Insect Princess" to have a card that powers up for every opponent's monster it destroys, or "Insect Queen" to have a monster that powers up for every opponent's monster on the field.
