This dragon is not the only one that gets more expensive, but more attack and less health. Other dragons are the same way. I don't think that this dragon needs to be buffed, and if it did, I believe that most of the other dragons would also need to be buffed. It works just fine, and is useful for getting high damage outputs fast. It can be a very strong card when used effectively. So no, I don't think it needs to be buffed.
