Riddle Repost: I am not a goblin, but I share their passion for machinery and blowing things up.
No one is gonna guess it, please be more specific.
I don't know what hint I can give without spoiling it. But check the cards in your collection, you may get to the answer very quickly, and then you will say "Of course! Why didn't I think about it earlier ?".
If no one guessed correctly before tonight (UTC +1) I will post a hint.
