As of today, the Hexblade has weathered 22 downvotes...enough to eliminate it twice over. Of those downvotes, most of them came from people who were upvoting Fiend (6), Genie (5), or Great Old One/Undead (4 each).
Similarly, the Celestial has weathered 19 downvotes, enough to eliminate it more than once. And of those downvotes, most of them came from folks who were upvoting Hexblade (7) or Seeker, Undead, and Fathomless (3 each). So the Celestial vs. Hexblade "feud" is rather one-sided; seems like Hexblade is trying to eliminate Celestial, but
everyone is trying to eliminate Hexblade.
And this is interesting: Archfey has enjoyed the fewest downvotes of any other option on the list (6). Heck, it didn't even get a single downvote until
page 8. So I'm going to have to revise my prediction:
I think the Archfey is gonna be the Survivor.
