Buggy source:
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  MageObject sourceObject=source.getSourceObject(game);
  if (controller != null && sourceObject != null) {
    Cards cards=controller.getSideboard();
    Card card=null;
    if (!cards.isEmpty()) {
      if (controller.chooseUse(Outcome.Benefit,choiceText,source,game)) {
        Set<Card> filtered=cards.getCards(filter,game);
        if (filtered.isEmpty()) {
          game.informPlayer(controller,"String_Node_Str" + filter.getMessage() + "String_Node_Str");
        }
 else {
          Cards filteredCards=new CardsImpl();
          for (          Card sideboardCard : filtered) {
            filteredCards.add(sideboardCard.getId());
          }
          TargetCard target=new TargetCard(Zone.OUTSIDE,filter);
          target.setNotTarget(true);
          if (controller.choose(outcome,filteredCards,target,game)) {
            card=controller.getSideboard().get(target.getFirstTarget(),game);
          }
        }
      }
    }
    Cards filteredCards=new CardsImpl();
    for (    Card exileCard : game.getExile().getAllCards(game)) {
      if (exileCard.getOwnerId().equals(source.getControllerId()) && exileCard.hasSubtype("String_Node_Str")) {
        filteredCards.add(exileCard);
      }
    }

        card=game.getCard(target.getFirstTarget());
      }
    }

Fixed version (ground truth):
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  MageObject sourceObject=source.getSourceObject(game);
  if (controller != null && sourceObject != null) {
    if (controller.chooseUse(Outcome.Benefit,choiceText,source,game)) {
      Set<Card> sideboard=controller.getSideboard().getCards(filter,game);
      List<Card> exile=game.getExile().getAllCards(game);
      Cards filteredCards=new CardsImpl();
      Card card=null;
      for (      Card sideboardCard : sideboard) {
        filteredCards.add(sideboardCard.getId());
      }
      for (      Card exileCard : exile) {
        if (exileCard.getOwnerId().equals(source.getControllerId()) && exileCard.hasSubtype("String_Node_Str")) {
          filteredCards.add(exileCard);
        }
      }
      if (filteredCards.isEmpty()) {
        game.informPlayer(controller,"String_Node_Str" + filter.getMessage() + "String_Node_Str");
      }
 else {
        TargetCard target=new TargetCard(Zone.OUTSIDE,filter);
        target.setNotTarget(true);
        if (controller.choose(outcome,filteredCards,target,game)) {
          card=controller.getSideboard().get(target.getFirstTarget(),game);
          if (card == null) {
            card=game.getCard(target.getFirstTarget());
          }
        }
      }
      if (card != null) {
        card.moveToZone(Zone.HAND,source.getSourceId(),game,false);
        controller.revealCards(sourceObject.getIdName(),new CardsImpl(card),game);
      }
