I wanted to show you an ultimate viable Troll Build.
When you think of Blitzcrank, you may not think that he`s viable in Mid, right?
I tested it and it worked! However, it`s not a real Troll Item-Build,
but a real Troll Lane for a Blitz. You ever saw him in Mid?
My mates flamed me a lot, but they didn`t thaught about his great scaling at Q and R.
So I farmed and farmed and killed and killed...
After the game my teammates were surprised.
I thaught about a Troll-Mobafire-Guide :P

I decided to play Blitz very offensive.

The only Item which brings some life is "Rylai`s Crystal Scepter"
and, in the Defensive Build, "Liandrys Torment".

You can play more tanky with a "Rod of Ages" and a "Warmorgs Armor".

The "Seraphs Embrace" is Viable to swap with a "Rod of Ages".

And the "Lich Bane" [in offensive Build]/ "Liandry`s Torment" [in defensive Build]
is viable to swap with a "Warmorgs Armor".

You MUST last hit good before you are Level 6.
Then you can easy kill a whole wave with your Ultimate.

Cause of the short Cooldown you can use the Ultimate to kill Minions.

Pros:

-High Q and R Damage
-low cooldown on Ultimate
-good against normal AP Carrys like Ahri etc.


Cons:

-bad against AP Caster like Fizz or Gragas etc.
-found nothing else :P
