However, perhaps Supercell needs something different than just duplicates. Take the Flying Machine for example. It is original because it is a flying weaker Musketeer, but the Jungle Tree adds new attributes that can't be contrasted to any other card in Clash Royale. It also might hone for many more cards in the future.
