I played a match with 2 Lunarch Veterans on the board, one with Journey to Eternity cast on it. The opponent cast Ethereal Absolution killing the Lunarch Veterans but the one with Journey to Eternity reappeared on the board as a 0/0 and remained as a graphical artifact for the rest of the game. The Lunarch Veteran also did not show up in the graveyard and was inaccessible for the rest of the game.
