Buggy source:
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  Player targetPlayer=game.getPlayer(source.getFirstTarget());
  Card sourceCard=game.getCard(source.getSourceId());
  if (controller != null && targetPlayer != null && sourceCard != null) {
    int payLife=controller.getAmount(0,controller.getLife(),"String_Node_Str",game);
    if (payLife > 0) {
      controller.loseLife(payLife,game);
      game.informPlayers(new StringBuilder(sourceCard.getName()).append("String_Node_Str").append(controller.getLogName()).append("String_Node_Str").append(payLife).append("String_Node_Str").toString());
      Cards cardsInHand=new CardsImpl();
      cardsInHand.addAll(targetPlayer.getHand());
      int count=Math.min(cardsInHand.size(),payLife);
      TargetCard target=new TargetCard(count,Zone.HAND,new FilterCard());
      Cards revealedCards=new CardsImpl();
      if (targetPlayer.chooseTarget(Outcome.Discard,cardsInHand,target,source,game)) {
        List<UUID> targets=target.getTargets();
        for (        UUID targetId : targets) {
          Card card=game.getCard(targetId);
          if (card != null) {
            revealedCards.add(card);
          }
        }
      }
      TargetCard targetInHand=new TargetCard(Zone.HAND,new FilterCard("String_Node_Str"));
      if (!revealedCards.isEmpty()) {
        targetPlayer.revealCards(sourceCard.getName(),revealedCards,game);
        controller.chooseTarget(Outcome.Exile,revealedCards,targetInHand,source,game);
        Card card=revealedCards.get(targetInHand.getFirstTarget(),game);
        if (card != null) {
          controller.moveCardToExileWithInfo(card,null,null,source.getSourceId(),game,Zone.HAND,true);
        }
      }
      return true;

Fixed version (ground truth):
@Override public boolean apply(Game game,Ability source){
  Player controller=game.getPlayer(source.getControllerId());
  Player targetPlayer=game.getPlayer(source.getFirstTarget());
  Card sourceCard=game.getCard(source.getSourceId());
  if (controller != null && targetPlayer != null && sourceCard != null) {
    int payLife=controller.getAmount(0,controller.getLife(),"String_Node_Str",game);
    if (payLife > 0) {
      controller.loseLife(payLife,game,false);
      game.informPlayers(new StringBuilder(sourceCard.getName()).append("String_Node_Str").append(controller.getLogName()).append("String_Node_Str").append(payLife).append("String_Node_Str").toString());
      Cards cardsInHand=new CardsImpl();
      cardsInHand.addAll(targetPlayer.getHand());
      int count=Math.min(cardsInHand.size(),payLife);
      TargetCard target=new TargetCard(count,Zone.HAND,new FilterCard());
      Cards revealedCards=new CardsImpl();
      if (targetPlayer.chooseTarget(Outcome.Discard,cardsInHand,target,source,game)) {
        List<UUID> targets=target.getTargets();
        for (        UUID targetId : targets) {
          Card card=game.getCard(targetId);
          if (card != null) {
            revealedCards.add(card);
          }
        }
      }
      TargetCard targetInHand=new TargetCard(Zone.HAND,new FilterCard("String_Node_Str"));
      if (!revealedCards.isEmpty()) {
        targetPlayer.revealCards(sourceCard.getName(),revealedCards,game);
        controller.chooseTarget(Outcome.Exile,revealedCards,targetInHand,source,game);
        Card card=revealedCards.get(targetInHand.getFirstTarget(),game);
        if (card != null) {
          controller.moveCardToExileWithInfo(card,null,null,source.getSourceId(),game,Zone.HAND,true);
