I didn't watch that much but....
Kog Maw every game.
Corki or Vayne for the other team
Janna, Soraka, Taric, Lulu, Alistar, Sona all get usage either support, jungle or solo lane.
Dr. Mundo was like most picked after Kog Maw.
Lee Sin was picked or banned often.
Cass, Ryze, Ahri, Morgana, Sion, Vlad were seen often.
Irelia and Shyvana I saw CLG run.
Maokai and Fiddlesticks were picked as well.
Forgot Kennen. He was definitely picked a lot too.
