Kunai of Retribution

To activate this action, as part of its cost, you will generate a delayed triggered effect that will destroy this dagger when the combat chain closes. Even If the dagger is destroyed before the combat chain closes, you are still considered to have paid the cost successfully.

If you attack with Kunai of Retribution, destroy it (e.g. by flicking), and then equip it from your graveyard, the newly equipped Kunai of Retribution is considered a new object and won’t be destroyed from the delayed triggered effect generated from activating it previously. If you activate this newly equipped Kunai of Retribution, it will be destroyed when the combat chain closes.
