At the beginning of each player's end step, if an artifact entered the battlefield under your control this turn, look at the top two cards of your library. Put one of them into your hand and the other into your graveyard.
The ability will trigger no matter what happened to the artifact after it entered. It may have left the battlefield, come under another player's control, or stopped being an artifact.

If there is only one card in your library, you put it into your hand.
