I would suggest playing talon either top or bot lane but that's just me if you want to play him in the mid that's fine to. Your main goal is to get fed as fast as possible in a short amount of time, the best way to achieve this is to have a good friend support you by whittling down their health and letting you jump onto them to execute them quickly. Once you get your first bloodthirster your going to do some heavy damage to them with a little bit of everything. just keep getting fed the entire game.
