Claimed: it happens for the player who claims it, whoever launched it, and at once (706.6). Put into your scrapyard: from anywhere but the board, for example dug from your hold or scrapped from your hand (D-157); it is in the scrapyard when it happens, so it can be one of the cards. You choose which when it happens: any cards, from none to 3, and see your whole scrapyard. Your hold is shuffled once, so you don't know where they land (D-157).
