What Champion(s) Should I One-Trick Season Eight?

Hey everyone! I have been playing LoL since pre-season six, and I really want to get to gold this season. I was able to peak at S2 56 or so LP in season 7, and I know I can do it. However, I need a champ to play to bring me there. I don't know who I want, but here is my checklist:

1. Has to have a decent late game (I don't want them falling off if my team sucks)
2. Not easy to play/Outplay potential (I can't stand playing brainless champions that everyone hates- it feels like cheating)
3. Low Pick/Ban rate preferred (I want to one trick the champion, so it would be nice if I got them nearly every game)

If you have an idea as to who I can play, I would love to hear it. Thank you! [slayer-pantheon-thumbs]
