There hasn’t been a set with a bunch of elves in it, but they have sort of snuck up on me by just being around on several sets. Ixalan has none and we are losing some from Kaladesh, but the losses are not major and there’s some very interesting ones on Ravnica. Some I didn’t even think of as elves.
Last weekend I played at GP Stockholm. I was picked up for the feature on the second round. As you may know, most of the early round features are not based on the same criteria as the latter rounds, where they focus on famous players and those in the running for Top 8. In my case (and I asked Tobi Henke about this), I was picked, and I quote “[they] had access to certain decklists”. It was my fault then.
