Rule 714.2
Official source text from the 1 July 2012 Rules release
All _Magic_ cards involved in the game that was restarted when it ended, including phased-out permanents and nontraditional _Magic_ cards, are involved in the new game, even if those cards were not originally involved in the restarted game. Ownership of cards in the new game doesn't change, regardless of their location when the new game begins. Example: A player casts Living Wish, bringing a creature card into the game from outside the game. Then that game is restarted. The creature card will be part of that player's library when the new game begins.
