- 4 October 2004If there is only one card in your graveyard, it is exiled by the first part of the effect and you do not get to put any cards into your hand since the second part fails.
- 15 October 2006It does not target the cards, but it targets the opponent. If you can’t target an opponent, you can’t activate this ability.
