I'm not trying to be unexcited, I'm trying to understand it. They asked for feedback. If this is a Yuletide-like challenge done halfway between Yuletides because the Yuletide challenge is so much fun and we want more, that could be made explicit in the write-up somewhere. It certainly would have cleared things up for me. If the other chromatic challenges are not for rare fandoms, but this one is, then that's the thing that sets it apart from the other chromatic challenges and could be pointed up a bit. That's all.
Re: rarity redundant?
