Suppose I use a Moat Lurker to remove a card that is, at the moment, annoying me. Something like "The Lich King".
What happens if I then play a card that takes this Moat Lurker off the board? Like say, Shadowstep, Vanish, or Sap, or other effects like Youthful Brewmaster that remove a card and return it to the hand?
Then I could play Moat Lurker on another card to destroy it, will Moat Lurker return both this second target AND The Lich King, or only the second target?
If this is indeed true, it could be pretty powerful in deck that can reliably return moat lurker to the hand.
