Personally I'd like to see another scaly champ. Maybe a reptilian vastayan? We already have renekton to fit the warrior archetype so this one could be a shaman/vodoo/witch doctor since we don't have a champ like that Maybe an assasin?
This is what I want more than anything. I wrote a thread about it a while back. https://boards.na.leagueoflegends.com/en/c/general-discussion/kbcqOLTc-a-distinct-lack-of-reptilian-champions
We already have 3 reptilian champions in League
= Medusa's archetype, the lamia we find in every MOBA games
= Crocodile archetype, inspired by the ancient Egyptian god Sobek
= Humanoid female shapeshifter dragonSo we already have Snakes, Crocodiles and Dragons (They don't exist ofc)
Plus we don't have to forget Skaarl who is actually a female Lizard
When I think of other reptiles we could get in League :
And I know frogs are amphibians and aren't part of the repitlian family but it would be cool to get a toad champion in the future (And no 
is not an amphibian but a catfish demon)
Oh and 
is kind of a mystery right now.
One of the ideas people were throwing around for the colorful mage was that it was a chameleon Vastaya. I don't think that's likely, though, but I guess we'll find out soon.
3 word, Vastayan Reptilian Butterflies. Their canon, now they just need to be a champion.
Honestly no...
Riot teased that we may get one of the original Vastayans, the Vastaysharei in the future. This could be one of them, a true shapshifter.
I would love to have a female champion with insect thematic.
