Mine work is to make your Blitz game more and even more pleasure :D
This is an amateur build so don't get me wrong ! You'll have to make your sense of running away and Getting into the battle on maximum heights!
Ok we are starting here at 1 lvl. You'll have to get clever and fast in playing defensive at the start of game.

Standard movement is killing minions and (if enemy is so stupid) catching him with Q skill onto a trap to the turret. That's hard work but it will give you large effects later.
For example. You see that the Miss fortune is beneath minions and tower.
What will you do?
on E then Q and lighting is on your side ;D
Later after 6 level if you've had more HP you could get into solo fights.
E/Q/R/W/E/Q
or E/Q/R/W (few hits (you could get an Sword of the occult (later you will sell it))) and ignite.
Your ultimate is good for team fights (in passive it does nice damage but If you'll click R at the end of build, damage is higher.) So go on to the team fights but not like a tank! Like a nuker .
Youre starting with E/Q. Take two of their team to fight with your teammate and then use your ulti.
2 kills!

In ahead article i was telling about Sword Of Occult.
Right item but wrong build huh?
Nah. Wrong.
It's good item but with it you'll have to get on with mana potions fast.!!!
Ah if you want nuke you could change warmog to a third rabadon but i am using Ryali's Crystal scepter HP + AP goes together really good ;D

Yah I wish you enjoy your ride with the lighting!
(sorry for my Broken English i am Polish)
As i sad it's amateur guide. Tell true about it.
