Buggy source:
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  MageObject sourceObject=game.getObject(source.getSourceId());
  if (controller == null || sourceObject == null) {
    return false;
  }
  TargetCardInLibrary target=new TargetCardInLibrary(0,2,new FilterBasicLandCard());
  if (controller.searchLibrary(target,game)) {
    if (target.getTargets().size() > 0) {
      Cards revealed=new CardsImpl();
      for (      UUID cardId : target.getTargets()) {
        Card card=controller.getLibrary().getCard(cardId,game);
        revealed.add(card);
      }
      controller.revealCards(sourceObject.getIdName(),revealed,game);
      if (target.getTargets().size() > 0) {
        TargetCard target2=new TargetCard(Zone.LIBRARY,filter);
        controller.choose(Outcome.Benefit,revealed,target2,game);
        Card card=revealed.get(target2.getFirstTarget(),game);
        if (card != null) {
          controller.moveCards(card,Zone.HAND,source,game);
          revealed.remove(card);
        }
        card=revealed.getCards(game).iterator().next();
        if (card != null) {
          controller.moveCards(card,Zone.GRAVEYARD,source,game);
        }
      }
 else       if (target.getTargets().size() == 1) {
        Card card=revealed.getCards(game).iterator().next();
        if (card != null) {
          controller.moveCards(card,Zone.HAND,source,game);
        }
      }
    }
    controller.shuffleLibrary(source,game);
    return true;
  }

Fixed version (ground truth):
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  MageObject sourceObject=game.getObject(source.getSourceId());
  if (controller == null || sourceObject == null) {
    return false;
  }
  TargetCardInLibrary target=new TargetCardInLibrary(0,2,new FilterBasicLandCard());
  if (controller.searchLibrary(target,game)) {
    if (target.getTargets().size() > 0) {
      Cards revealed=new CardsImpl();
      for (      UUID cardId : target.getTargets()) {
        Card card=controller.getLibrary().getCard(cardId,game);
        revealed.add(card);
      }
      controller.revealCards(sourceObject.getIdName(),revealed,game);
      if (target.getTargets().size() > 0) {
        TargetCard target2=new TargetCard(Zone.LIBRARY,filter);
        controller.choose(Outcome.Benefit,revealed,target2,game);
        Card card=revealed.get(target2.getFirstTarget(),game);
        if (card != null) {
          controller.moveCards(card,Zone.HAND,source,game);
          revealed.remove(card);
        }
        if (!revealed.isEmpty()) {
          card=revealed.getCards(game).iterator().next();
          if (card != null) {
            controller.moveCards(card,Zone.GRAVEYARD,source,game);
          }
        }
      }
 else       if (target.getTargets().size() == 1 && !revealed.isEmpty()) {
        Card card=revealed.getCards(game).iterator().next();
        if (card != null) {
          controller.moveCards(card,Zone.HAND,source,game);
        }
      }
