Effect
When your opponent adds a card(s) from their Deck to their hand, except by drawing them (except during the Damage Step): You can send that card(s) to the GY, and if you do, inflict 800 damage to your opponent. This effect can only be used once while this card is face-up on the field.
This is a Trigger Effect that can be activated optionally when your opponent adds a card(s) from their Deck to their hand by a method other than drawing.
This effect does not target.
This effect cannot be activated during the Damage Step.
The process of sending the added card(s) to the Graveyard and the process of inflicting 800 damage to your opponent are treated as occurring simultaneously.
