Déjà-vu
Event
206.1-4
First return the top card from the discard pile on top of the draw pile, from where it is subsequently pushed up again through the Chrono-Matrix. Since the event on this card is already known, it can remain face up. Then discard the déjà-vu card as usual. Déjà-vu is possible for both negative and positive events (including energy crystals).
