Yet again, we have an episode that involves all of the Mane Six.  This seems to be happening more often in Season Four.  But unlike Testing, Testing, 1, 2, 3, where each of the Mane Six gets their moment to shine but don't really have the focus of the story.  Trade ya actually gives each of the Mane Six their own little story arc within a single episode.
