Text(US+errata): Whenever a creature is put into a graveyard and another creature is in play, return the first creature from that graveyard to play under its owner's control at end of turn. [Oracle 99/07/21]
It works for all players and has errata to remove the "your graveyard" text. [bethmo 98/10/02]
Only triggers on a creature card going to the graveyard from play. When a card goes to the graveyard from someplace other than "in play", it is not a creature. [WotC Rules Team 98/10/18]
It checks to see if there are any creatures in play controlled by any player at the time the creature is put into the graveyard. If there are, it will put the creature back even if there are no creatures in play at the end of turn. [Urza's FAQ 98/10/05]
The creature comes back even if Lifeline leaves play. [Urza's FAQ 98/10/05]
It brings the card back even if the card was a creature only due to a spell or ability. It comes back as if newly cast, however. [WotC Rules Team 98/10/18]
If more than one creature is in play and all the creatures in play go to the graveyard at once (such as with Wrath of God), then all of them are returned at end of turn. [WotC Rules Team 98/10/18] This is because all "leaves play" triggers that check the state of the game check the game state at the time right before the card left play. See Rule A.4.21. [D'Angelo 98/11/17]
It fails to bring the creature back if the creature is not still in the graveyard at the end of turn. [D'Angelo 98/10/12]
If multiple creatures are coming back, they come back one at a time, not all at once. This is because Lifeline triggered once for each creature and set up a separate "at end of turn" effect for each. [D'Angelo 98/11/17]
There is no way to get an infinite loop with this card. This is because "at end of turn" triggers that happen after you start dealing with this turn's "at end of turn" triggers will wait until the following turn to be played. [D'Angelo 99/05/01]
