What are the top 5 troll champs in the game right now??

So I haven't played League in a long time. I played almost daily in season 4 and half of season 5. Since then I haven't followed the game very much at all. I was thinking about playing a few games just to see if I enjoy it as much as I used to. I just have no idea which champs to pick.

I was wondering what the top 5 troll picks are. Is it still teemo, singed, urgot, Galio and skarner? That's what it used to be. Thanks to the feedback!
