Buggy source:

  Player targetPlayer=game.getPlayer(source.getFirstTarget());
  Player controller=game.getPlayer(source.getControllerId());
  MageObject sourceObject=game.getObject(source.getSourceId());

    targetPlayer.revealCards(sourceObject.getIdName(),targetPlayer.getHand(),game);
    TargetCard target=new TargetCard(Zone.HAND,filter);
    target.setNotTarget(true);
    Card chosenCard=null;
    if (controller.chooseTarget(Outcome.Benefit,targetPlayer.getHand(),target,source,game)) {
      chosenCard=game.getCard(target.getFirstTarget());
    }
    FilterCard filterNamedCards=new FilterCard();
    if (chosenCard != null) {
      filterNamedCards.add(new NamePredicate(chosenCard.getName()));
      filterNamedCards.setMessage("String_Node_Str" + chosenCard.getName());
    }
 else {
      filterNamedCards.add(new NamePredicate("String_Node_Str"));
    }
    Cards cardsToExile=new CardsImpl();

        }
      }
      TargetCard targetCardsHand=new TargetCard(0,Integer.MAX_VALUE,Zone.HAND,filterNamedCards);
