Rabiah Scale, part 1
* Kamigawa and Lorwyn/Shadowmoor are still unlikely to return, since they're unpopular even in recent market research.
* Kaladesh is middle of the road, which surprises MaRo.
*
Alara's shards are more popular than Alara together.
* Amonkhet was popular, but people were bummed out by the ending. Finding a way to get back from blowing up the setting is a bigger issue with a return than any problem the audience had.
* Ixalan was popular early on, but lost a lot of it as the sets came out, showing people liked the idea but not the mechanical execution.
