I'm Gonnal Pick Lina Inverse from Dota 2
Source
Lina has been one of the top core pick for Mid Heroes in Dota two because of his laning ability and early cool downs on her skill. Plus third and 4th were all extremely important in the final stages of the game.
With Lina's 3rd skill, she is extremely versatily when it comes to your type of build. :)
