Rule 713.2
Official source text from the 1 May 2011 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. 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.
