Mark Rosewater ranked his Magic: The Gathering set designs from best to worst. Rosewater has been at Wizards of the Coast since 1995 and has successfully led or co-led the design of 28 sets.

Of the 28 sets he listed, the following sets comprised the Top Ten:

  1. Innistrad
  2. Ravnica
  3. Unstable
  4. Kaladesh
  5. Future Sight
  6. Dominaria
  7. War of the Spark
  8. Throne of Eldraine
  9. Unglued
  10. Zendikar

Among the Top Ten, War of the Spark and Throne of Eldraine are the two most recent sets, and likely still available in retail game stores. He noted that Innistrad was in the top slot because it was his "tightest design", and Ravnica ranked a close second because it "fundamentally changed a lot of how we design sets."

On the other end of the spectrum, the self-admitted worst set designs on his part were:

     25. Ixalan
     26. Unhinged
     27. Eventide
     28. Battle For Zendikar

The most recent poor designs on this list were Ixalan and Battle For Zendikar. The basement slot was reserved for Battle For Zendikar not because it was actually the "worst set", but because he made a "fundamental mistake" in making the set "all about the war with the Eldrazi."    

In August, Mark Rosewater gave a State of the Union-style review of Magic set design (see "Head 'Magic' Designer Identifies Highlights and Lessons from Year's Releases").
