This is the ultimate Blitz AD/TANK build. This build is so awesome because of the huge amount blitzcrank deals and he is very tanky too

I took with the runes armor penetration and attack speed. That is because ad/tank blitzcrank needs armor pen and att. speed because you don't buy items with armor pen and not enough items with att speed.

I just took the normal attack masteries with mana because at the beginning Blitzcrank has too less mana and at the end the xtra mana is converted in attack damage because of manamune.

In my build I chose for ad with lots of armor and magic resist. The manamune is for ur manabarrier and it gives xtra ad too. The mercury's treads are for tenacity. The trinity force for att speed and mana and movement speed and the maw of martorius because of its magic resist, attack damage and the shield. Frozen heart for the xtra mana and armor and the guardian angel for the revive and the xtra magic resist and armor.

Pros:
- Lost of damage
- Easy to farm
- Tanky too
- Fun to play with
- Grabs can change a fight

Cons
- Mana problems early game
- Grabs are difficult
