Let's keep this short and simple.

I am currently pretty much maining mid lane, while trying to carry the gold's finest and myself to platinum. As of now, I have 2 favorite champions there, TF and Zyra, sometimes I go Kassadin.

Today I thought it'd be cool if I enlarged that list by 1-2 champions, so I'm open to suggestions:

What mid lane champion do you think I should start playing? What champion do you think has the power to massacre the enemy team and carry my team to victory?

I prefer hard-hitting glass cannons that snipe the enemies from the backlines and rely on good positioning. This does not mean I am not open for melee champions, however, or champions that poke and go balls deep afterwards.

I am currently thinking Kennen and Lissandra as interesting options. Whatcha think?
