I like Anivia-without bias-for not relying on my team actually. If you have good positioning you can stall the game by yourself with your ult. And you can easily, EASILY, catch out bad players with w late game. Honestly one of the best champions for turning games around single handedly. I've been in a game where we were down 30+ kills and probably 15k~ gold where I stalled their push with my waveclear, and then after 45 ish minutes I caught out their adc/support/mid with my wall and we pushed to win. It's doable every game below gold~ because people don't really know how to close out games.(assuming they dont have ridiculous dive, but even then if you have zhonyas you can possibly outplay with zhonya bait + wall to catch them out of position).
