FIZZ BUILDS?

I'm just starting to learn Fizz because I want to develop a strong melee mid champ. Of course I'm rushing a lich first and then getting sorc boots. I have also been building a Zhonyas and Rabs, but the other two items i have been shuffling around a bit. I have been building a nashors tooth with mixed results but it seems to compliment his kit well. Any other helpful suggestions for Fizz builds would be appreciated. Thanks!
