Effect
When your opponent Special Summons a monster(s) from the hand or Extra Deck: Shuffle that monster(s) into the Deck, then you lose 1000 LP for each returned monster.
This effect does not target.
This effect cannot be activated during the Damage Step.
This effect can only be activated when your opponent successfully Special Summons a monster(s) from their hand or Extra Deck. (This includes Special Summons that occur via an effect that creates a Chain Link, as well as Special Summons that do not create a Chain Link. It can also be activated when your opponent successfully Pendulum Summons.)
The process of "return that monster(s) to the owner's Deck" and the process of "you lose 1000 LP for each monster returned" are not treated as happening at the same time.
