When one or more cards become Detached, they cease to be in the Attached state. 1. To represent this, these cards should no longer be placed under the card they were previously placed under as Top-Most Card. 2. If the Top-Most Card no longer has any cards Attached to it after this, it is no longer a Top-Most Card.
