This is a somewhat delicate matchup. Both decks have nigh-unbeatable draws, and games can be quite precipitous. The difference between, say, playing an accelerant to help offset a land-light draw, versus losing it to a Drill Bit, can make the rest of the game look either pedestrian or impossible.
That said, this one did turn out kind of harsh. It's almost exactly 60/40 for Empty Throne, which is outside the range I consider "successful," even for an event that only requires one win. (For some background, the enchantments deck had a lot of trouble taking off during testing - too many hands that just petered out or folded to a little disruption. I spent multiple iterations boosting its resiliency and adding a little inevitability, but it seems I Went Too Far.)
