I think she's Mundo (Yeah Mundo). Can regenerate, throw sword and goes where she please.
I guess that makes Madoka Super-Ashe (insta-kill arrow), Mami -> Catlyin or Graves and Homura Zilean.
Homura i was thinking like Twisted Fate just for the ports
Aside from the regen Sayaka could be Irelia
Discovered the joy of GP
