Ok! Ahri would be the best idea for the middle laner of arcade! Her Fox Fires (W) would be arcade coins, her Orb of Deception (Q) would be a pixelated version of her former Orb of Deception, her Charm (E) would be a pixelated heart with that white shiny effect on it and her Spirit Rush (R) would be really cool blue glitches that would make a glitch sound effect! Her recall, would be her putting a token in a token machine and it could say (One more life) and then it would make her have an pixelated recall effect. When she dies it erases her high scores (Fake high scores). I hope this idea goes through to you riot! :D if not, thanks for checking out my post!
