Buggy source:

  Player controller=game.getPlayer(source.getControllerId());
  MageObject sourceObject=game.getObject(source.getSourceId());
  Card chosenCard=game.getCard(getTargetPointer().getFirst(game,source));
  if (chosenCard != null && sourceObject != null && controller != null) {
    Player owner=game.getPlayer(chosenCard.getOwnerId());
    if (owner == null) {
      return false;
    }
    FilterCard filterNamedCard=new FilterCard();
    filterNamedCard.add(new NamePredicate(chosenCard.getName()));
    for (    Card checkCard : owner.getGraveyard().getCards(game)) {
      if (checkCard.getName().equals(chosenCard.getName())) {
        controller.moveCardToExileWithInfo(checkCard,null,"String_Node_Str",source.getSourceId(),game,Zone.GRAVEYARD,true);
      }
    }
    filterNamedCard.setMessage("String_Node_Str" + chosenCard.getLogName() + "String_Node_Str"+ owner.getLogName());

      return false;
    }
    FilterCard filterNamedCard=new FilterCard();
    String nameToSearch=chosenCard.isSplitCard() ? ((SplitCard)chosenCard).getLeftHalfCard().getName() : chosenCard.getName();
    filterNamedCard.add(new NamePredicate(nameToSearch));
    for (    Card checkCard : owner.getGraveyard().getCards(game)) {
      if (checkCard.getName().equals(chosenCard.getName())) {
        controller.moveCardToExileWithInfo(checkCard,null,"String_Node_Str",source.getSourceId(),game,Zone.GRAVEYARD,true);
      }
    }
    filterNamedCard.setMessage("String_Node_Str" + chosenCard.getLogName() + "String_Node_Str"+ owner.getLogName());
