The Argument Dragon looks like it is the Rare dragon for the Emotion Explorers Dragon Tales but it has an Ultra Rare status and 22 hours. That will be a real time crunch when trying to complete the acts. Maybe that is an intended new change but in case it's an accidental switch I thought I would leave a note. Thanks!
