Can you see if a card was created by an Unstable Portal or Webspinner in the log?

As you may know Hearthstone has an output_log.txt, which you can enable in the log.config. Here you can see a whole bunch of information about the game, which cards have been played and so on. Is there a way to see if a card was created by another card's effect, such as Unstable Portal or Webspinner? I know that you can obviously do this by looking at the card in-game, but I need to read it from the log, if possible.

I know this is a long shot, but if anyone has some information or ideas on this, please let me know.


It turns out to be pretty simple, as long as you know the trick. Card played have an ID in the zone log and if that ID is above 67, the card was created by some other card or effect. This won't work if the card is played, returned to the hand, then played again, but there might be an easy way to track this as well. If nothing else, you could still track the position of the card in the hand.
