Draven.
The name says enough, OP!
He can do so much damage with his axes.
Enjoy my quick guide!

For runes, you can try lifesteal instead of armorpen.
You can choose scaling armor/magic resist. or flat armor/magic resist.

Your masteries are there so you can play very aggresive because Draven needs to poke much with his axes.
You have to stay alive, that's why it's a bit deffensive.

In early game you need lifesteal and attack speed to farm minions.
In mid game you go for damage and crit.
In late game you need armorpen. for killing the tanks very easy.

Too catch you axes, you should buy a phantom dancer. With a phantom dancer you can move through minions and catch all of your axes!

You always have to try to catch your axes.
You have to catch your axes so you get a stack of adoration.
With adoration you gain more gold (See summary)

For summoner spells try barrier and flash, so you can stay alive!

Draven's passive:
You get 1 stack of adoration everytime you kill a minion or catch a spinning axe.
Everytime you kill a champion, you gain 50 + stacks of adoration * 2 bonus gold.

Try to last hit with your spinning axes, if there isn't a minion to last hit, poke a champion!
