As a permanent-event, playable on a face-down agent who was brought into play this turn. When the agent is revealed, and if his home site is a Shadow-hold [S] or a Dark-hold [D], the site where he came into play (which is not represented by a card) may legally be any Shadow-hold [S] or a Dark-hold [D]. Discard when the agent is revealed. Alternatively, as a short-event, take any agent who has a home site that is a Shadow-hold [S] or a Dark-hold [D] from your play deck into your hand (reveal it to your opponent and reshuffle your play deck).
