When Ivory Gargoyle is put into a graveyard from the battlefield, return it to the battlefield under its owner's control at the beginning of the next end step and you skip your next draw step.
10/1/2008: The player who controlled Ivory Gargoyle when it was put into a graveyard will skip his or her next draw step even if Ivory Gargoyle is returned to the battlefield under a different player's control (because it's owned by someone else) or isn't returned to the battlefield at all (because it left the graveyard before the end of the turn, for example).
10/1/2008: The second ability can be activated only if Ivory Gargoyle is on the battlefield.
