As simple as the title says. 
would be in classic Gym clothes. All of her abilities will be turned into Dodgeballs (possibly flaming dodgeballs).
Also a good idea for the image would be for her to be standing on a pile of 4 champions whom were KO'd by her, with imprints on their foreheads. Also, she'd be throwing a Dodgeball at a nerdy-looking Heimerdinger whom is also running away in fear.

well she doesn't exactly throw them
ModWulf Helhammer1 votesHer ult and her W? Ahri only has one ability where she throws out her orb (also if being pelted by a bunch of spheres doesn't scream "dodgeball!" to you, I don't know what does)
