Buggy source:
@Override public boolean apply(Game game,Ability source){
  Spell spell=game.getStack().getSpell(targetPointer.getFirst(game,source));
  MageObject sourceObject=source.getSourceObject(game);
  if (sourceObject != null && spell != null) {
    Player spellController=game.getPlayer(spell.getControllerId());
    if (spellController != null && spellController.moveCardToExileWithInfo(spell,source.getSourceId(),sourceObject.getIdName(),source.getSourceId(),game,Zone.STACK,true)) {
      if (spellController.getLibrary().size() > 0) {
        Library library=spellController.getLibrary();
        Card card;
        do {
          card=library.removeFromTop(game);
          if (card != null) {
            spellController.moveCardToExileWithInfo(card,source.getSourceId(),sourceObject.getIdName(),source.getSourceId(),game,Zone.LIBRARY,true);
          }
        }
 while (library.size() > 0 && card != null && !sharesType(card,spell.getCardType()));
        if (card != null && sharesType(card,spell.getCardType()) && !card.getCardType().contains(CardType.LAND) && card.getSpellAbility().getTargets().canChoose(spellController.getId(),game)) {
          if (spellController.chooseUse(Outcome.PlayForFree,"String_Node_Str" + card.getLogName() + "String_Node_Str",source,game)) {
            spellController.cast(card.getSpellAbility(),game,true);
          }
        }
        ExileZone exile=game.getExile().getExileZone(source.getSourceId());
        if (exile != null) {
          while (exile.size() > 0) {
            card=exile.getRandom(game);
            exile.remove(card.getId());
            spellController.moveCardToLibraryWithInfo(card,source.getSourceId(),game,Zone.EXILED,false,false);
          }

Fixed version (ground truth):
@Override public boolean apply(Game game,Ability source){
  Spell spell=game.getStack().getSpell(targetPointer.getFirst(game,source));
  MageObject sourceObject=source.getSourceObject(game);
  if (sourceObject != null && spell != null) {
    Player spellController=game.getPlayer(spell.getControllerId());
    if (spellController != null && spellController.moveCardToExileWithInfo(spell,source.getSourceId(),sourceObject.getIdName(),source.getSourceId(),game,Zone.STACK,true)) {
      if (spellController.getLibrary().size() > 0) {
        Library library=spellController.getLibrary();
        Card card;
        do {
          card=library.removeFromTop(game);
          if (card != null) {
            spellController.moveCardToExileWithInfo(card,source.getSourceId(),sourceObject.getIdName(),source.getSourceId(),game,Zone.LIBRARY,true);
          }
        }
 while (library.size() > 0 && card != null && !sharesType(card,spell.getCardType()));
        if (card != null && sharesType(card,spell.getCardType()) && !card.getCardType().contains(CardType.LAND) && card.getSpellAbility().canChooseTarget(game)) {
          if (spellController.chooseUse(Outcome.PlayForFree,"String_Node_Str" + card.getLogName() + "String_Node_Str",source,game)) {
            spellController.cast(card.getSpellAbility(),game,true);
          }
        }
        ExileZone exile=game.getExile().getExileZone(source.getSourceId());
        if (exile != null) {
          while (exile.size() > 0) {
            card=exile.getRandom(game);
            exile.remove(card.getId());
            spellController.moveCardToLibraryWithInfo(card,source.getSourceId(),game,Zone.EXILED,false,false);
          }
