It was a toss up between this episode and “Pickle Rick”. The only edge that “Pickle Rick” has is the merchandising part. “The Ricklantis Mixup” is the epitome of what ‘Rick and Morty’ is all about. With multiple plots, angles and clues, it was visible on that sole episode how the producers of the show respect the legions of fans of their show. Probably the biggest reveal on that episode is when evil Morty returns.
