Kind of like the backing animations for LCS skins, they could be based on in-jokes associated with those players and a champ they're often known for playing at some point or simply a favorite champ of theirs. I believe they would sell even better than hit favorites like Smug Ashe, the 2 penguins, and Fiora.

As much as I like LilyPichu and would instabuy an emote like that, isn't her common method of joke associated with Lux just quoting her usually?
I'm having a hard time coming up with anything specific that could come across through an emote...
Chembaron Yamada2 votesThere are options for that. For example, they could release a Lux emote with Lilypichus art style.
Make an emote with a "Oh, I messed up" pose of Dark Elementalist Lux with her art style and call it Dux. ^^
