Buggy source:
@Override public boolean applies(GameEvent event,Ability source,boolean checkPlayableMode,Game game){
  if (event.getType() == GameEvent.EventType.PLAY_LAND || event.getType() == GameEvent.EventType.CAST_SPELL && game.getOpponents(source.getControllerId()).contains(event.getPlayerId())) {

Fixed version (ground truth):
@Override public boolean applies(GameEvent event,Ability source,boolean checkPlayableMode,Game game){
  if (event.getType() == GameEvent.EventType.PLAY_LAND || event.getType() == GameEvent.EventType.CAST_SPELL && game.getOpponents(source.getControllerId()).contains(event.getPlayerId())) {
    final Card card=game.getCard(event.getSourceId());
    final Player opponent=game.getPlayer(event.getPlayerId());
    if (card == null || opponent == null) {
      return false;
    }
    if (card.getCardType().contains(CardType.CREATURE) && game.getBattlefield().countAll(new FilterCreaturePermanent(),opponent.getId(),game) > game.getBattlefield().countAll(new FilterCreaturePermanent(),source.getControllerId(),game)) {
      return true;
    }
    if (card.getCardType().contains(CardType.ARTIFACT) && game.getBattlefield().countAll(new FilterArtifactPermanent(),opponent.getId(),game) > game.getBattlefield().countAll(new FilterArtifactPermanent(),source.getControllerId(),game)) {
      return true;
    }
    if (card.getCardType().contains(CardType.ENCHANTMENT) && game.getBattlefield().countAll(new FilterEnchantmentPermanent(),opponent.getId(),game) > game.getBattlefield().countAll(new FilterEnchantmentPermanent(),source.getControllerId(),game)) {
      return true;
    }
    final int yourLands=game.getBattlefield().countAll(new FilterLandPermanent(),source.getControllerId(),game);
    if (card.getCardType().contains(CardType.LAND) && game.getBattlefield().countAll(new FilterLandPermanent(),opponent.getId(),game) > yourLands) {
      return true;
    }
  }
  return false;
