217.7d.

A card may have one ability printed on it that removes one or more cards from the game, and another ability that refers either to "the removed cards" or to cards "removed from the game with [name]." These abilities are linked: the second refers only to cards in the removed-from-the-game zone removed as a result of the first. If another object copies both abilities, the abilities will be similarly linked on that object. They can't be linked to any other ability, regardless of what other abilities the object may currently have or may have had in the past.

Example: Arc-Slogger has the ability "{R}: Remove the top ten cards of your library from the game: Arc-Slogger deals 2 damage to target creature or player." Sisters of Stone Death has the ability "{B}{G}: Remove from the game target creature blocking or blocked by Sisters of Stone Death" and the ability "{2}{B}: Put a creature card removed from the game with Sisters of Stone Death into play under your control." Quicksilver Elemental has the ability "{U}: Quicksilver Elemental gains all activated abilities of target creature until end of turn." If a player has Quicksilver Elemental gain Arc-Slogger's ability, plays it, then has Quicksilver Elemental gain Sisters of Stone Death's abilities, plays the remove-from-game ability, and then plays the return-to-play ability, only the creature card Quicksilver Elemental removed from the game with Sisters of Stone Death's ability can be returned to play. Creature cards Quicksilver Elemental removed from the game with Arc-Slogger's ability can't be returned.
