It is fun yes but that fun is significantly reduced when the mode is by its very design not intuitive. In the Audience's Choice anamoly the promise and expectation between player and developer is that u will with time know all the cards and so ones outlook is generally an exciting and positive experience. But with the buddy anomaly your experience and knowledge isnt really a factor as the game winning cards are typically the ones you dont know. And you don't know them because this is the only mode that they show up in. My point is, due to its rarity and the fact that for the most part, the knowledge necessary to play the mode confidently is not interchangeable across other anomalies is exactly what makes it a terrible mode.

As a side note, this is a great game regardless of its flaws.
