  Official Ruling
  The last ability will trigger only if Auntie's Snitch is in your graveyard at the moment a Goblin or Rogue deals combat damage to a player. The ability will check again when it tries to resolve. If Auntie's Snitch hasn't left the graveyard by this time, you may return it to your hand.
