Revealed is a temporary state and is not a zone. 1. Other cards, including the card being revealed, can reference the act of being Revealed. 2. Cards remain in the zone they are being Revealed from. Example: If a card is being Revealed from the top of a player's Main Deck, it is still the top card of that player's Main Deck. 3. The state of being Revealed lasts for the duration specified by the game effect that applied the state; if there is no duration specified and the state was caused by a Reveal action as instructed by a spell or ability, it lasts until the resolution of that spell or ability finishes.
