text: If an activated ability of a card in exile references the card it's printed on by name, treat Dark Impostor's version of that ability as though it referenced Dark Impostor by name instead. For example, if Marrow Bats (which says "Pay 4 life: Regenerate Marrow Bats") is exiled with Dark Impostor, Dark Impostor has the ability "Pay 4 life: Regenerate Dark Impostor."
