P.S ( Plz upvote if you like)

Runes honestly don't matter at all and so I don't use them. If you are as good as me you wont need them either.

For Masteries I like to go 30,30,30 for maximum mastery of my opponents

Believe it or not items are important in League of the Legends. If you dont buy any you might not win the game so it is important to but items. I like to rush Guardian Angle because it brings you back to life whenever you die, so you become invincible ( even though Heimerdinger already is) Then I like to get 5 Rabadons Deatchaps for maximum AP... mwhahahaha

Pros

As Chaox says,"Arguably the best champ in League"
So OP ( over powered )
Invincible with Guardian Angel
Guaranteed 1 Penta Kill per game

Cons

Looks like a white person's testicle ( ewwww )

How to Jungle

Put Turrets Down
Throw Grenade
Smite Monsters
Smite again if you have been fighting a monster for more than 300 seconds
Shoot Missiles
Get Buff
Run Away
Message teammates " You are welcome "

Team Work is not much of an issue
If you follow my guide you should be able to kill the whole other team in about 3 hits leaving the rest of your own team to defend the turret next to the shop ( because it is the most powerful, and it protects the shopkeeper )
