We're all so caught up with Star Guardian, we forget Battle Academia exists
So in this particular discussion, I want to address the next group of champions that will get the Battle Academia skins or in other words, the champions that I want to see in the Battle Academia skinline. I would also address ALL the champions that has potential to be in this skin line. Of course I would not include those that already got the skins which are:

I would also not include the Academy skins since I kind of believe they're in the same universe which are:

Just to be clear, this is just my opinions and predictions, feel free to also create your own team in the comments, I would LOVE to see it. So to start of, Star Guardian is one of the best selling skinline in LoL, part of why it is I believe is because it's inspired by some anime. Since the debut of Battle Academia, I believe this skinline has potentials too since it is also inspired by anime.
**A quick disclaimer, I might express the word "short skirt" a lot in this discussion, just to be clear I'm not a pervert or anything. I just think that a lot of the champion that I will mention later would look elegant and beautiful wearing casual cloth or school uniform. Its just that, one of my favorite women's garment is a short skirt. **
So first of all, knowing that the principal of Durandal Academy is a cat
I honestly think almost ALL of the champion in LoL are suitable to be in this skinline. However I'll just pick some that I would love to see in this universe which are:

SETT and 
Okei thats all I wanted to say, feel free to give me a piece of your mind and tell me who do YOU like to see in the next batch of Battle Academia skin [sg-jinx]
- This is a choice I doubt anyone saw coming...and considering how outdated he is for a new skin (honestly, I'd like him to get a mini-rework too) I'm sure this is probably one of my most controversial nominations. But he fits the heart of the skinline rather well - he's young enough to fit the genre, he's very anime-esque already in how he acts canonically since he's always pushing himself to be "the best", and he's actually got a pretty good kit that fits rather well into BA, balancing his weapon along with supplemental magical arts. His rather unique style of fighting is also a boon to this skin line - showing a combination of martial skill with the tactical wit to back it up, and the magic to supplement both.
- My take for Syndra is an interesting one...the BA lore (when talking about Prestige Lux) lists "a certain rogue god weapon" and I think that Syndra could fit the role of the rogue perfectly. Her entire character arc is after one thing - power. Her power is already nutty, and she certainly has more than enough power canonically to be more than a rival/match for Lux. He sheer brute force, coupled with her innate character design, make her a clear candidate for this place. (As a quick honorable mention note, LeBlanc could also fit in this slot, as a rogue professor)
