We were unsatisfied with the lack of backstory provided for Uchbenbak, The Great Mistake in Caverns of Ixalan. In one of our first videos, Julie declared that she would write its story - and did she ever.
We chose to provide no additional commentary as it would detract from the story itself, but let us know if there's anything you'd like to know about it, and we'll address it in a future video.
