Here is my first build that i wish to share with others and as you can see he is hybrid.

i use these runes because attack speed is good to his passive and the armor is good in the begining to take more damage

i use 27/0/3 to maximize his damage and ability power as much as possible

dorans ring is good in the begining it will make him less squeshiey and it will make his Q damage more berserkers greaves is good to make his passive better so that he can use abilities quicker and faster. Hextech gunblade gives him some damage, ability power and spell vamp and life steal by buying this you will be able to survive more easily and you can kill easely :) guinsoos rageblade is good to make you stronger the more you fights. i took tiamat with it because it will make you a VERY good farmer and it also gives you health and mana reg. nashors tooth will make your passive even better and the cooldown reduction is good to your shield and your ulti and the ability power will make your abilities better.
rylai´s scepter is good when chasing (or escaping from) enemies it will also make you capable of more damage.

take q in the begining because it is good in first blood because it have low cooldown and it slows enemies. i dont now what more to say :/

I take flash because it is good for everybody it is good in both escaping and chasing.
i take clarity because it is important to have enough mana when attacking enemies.

that´s all i have to say hope you can use it and rate this good :)
