Effect
When your opponent activates a Spell/Trap Card with the same name as one in your Graveyard: Negate the activation, and if you do, destroy that card. Then you can add 1 card with that name from your Graveyard to your hand.
This is a Counter Trap card that you activate by directly chaining to the activation of a Spell/Trap card, when your opponent activates a card with the same name as a Spell/Trap card in your Graveyard. You cannot activate "Retaliation" against the "activation of an effect" of a Spell/Trap card, such as when the effect of a Continuous Spell or Continuous Trap card already face-up on the field is activated.
If you cannot apply the "negate the activation and destroy it" effect processing, you cannot apply the "then" effect processing that follows.
