Who am I? (Hint it's a super duper overloaded and majorly over powered champion)

I have insane mobility, A knock up, A ability on a 12 second cooldown that stops almost every projectile in the entire game, It doesn't matter how bad I do, as long as the game hits 35 minutes we win, I build only 2 crit chance items, and obtain 100% crit chance. Ohhh, and I have a shield that's broken as hell as a Passive, and I also get free armor penetration.

WHO IS IT?

Remember, It's a super overpowered champion, who basically gets an instant win after 35 minutes into the game.
