Ur Most Important Spell,you gain it at level 1,and gives you like 2000 shield on big levels

Your Ganking spell,your gank destruction spell,your turret attacking spell,many uses,EPIC SPELL,take it at level one but maximize the last

More MS,More AS,better than RG IMO after level 1....

Triple Damage with E,actualy 350% of your normal attack damage plus 200% of your Bonus Attack Damage,STILL GOOD!

HUGE DAMAGE even without ap!Team fight spell,Massive silence spell,epic spell

Imo it is the best,because u can escape through wall,"Me grabbing minions on Summoner's Rift like BAWCE!OH no!The other team is ganking me!No problem Baron is nearby,i can flash over the wall!I overdrive and make it with 50 hp!OH NO,MY PASSIVE LIGHTNING CAN HIT BARON!!!FUUUUUU---

101 time,Best 1v1 spell...
Good options

You can use it as an heal,if you have low mana and there is just a little bit til they get you on 30% hp,and many other options

YES YES I KNOW THE TROLL SPELL!,But it is good,until lvl 30 my combo was and ,it helps to trick your enemies,you have low hp,he has low hp too,but with 200/300 more,you heal,he cries,he dies...

EPIC GANKING SPELL!!!!

Take it if you dont have enough anti healers,also the true damage is pretty nice

Stacking mana with items like Manamune and Frozen Heart will increase the effectiveness of his Mana Barrier.
Blitzcrank can be effective at tank, damage per second, and support roles. A tank should get items that give mana and survivability, a DPS should get Manamune and Sheen (and later a Trinity Force), and a support (crowd control) should get cooldown reduction to be as disruptive as possible.
Manamune synergizes with Blitzcrank extremely well. It increases his attack damage, and the potential 1350 mana increases the effectiveness of Mana Barrier. This item is universal in nearly every Blitzcrank build./
Alternatively, Manamune can be replaced with Archangel's Staff and on an AP/Tank hybrid with other AP + HP items such as Rod of Ages and Rylai's Crystal Scepter.
Sheen, and later Trinity Force can greatly increase the damage output of Blitzcrank's standard combo, as well as increase the strength of his Power Fist and Mana Barrier.
Frozen Heart and Banshee's Veil are great items for a Tanky-Support Blitzcrank, as they provide mana for your Manamune and Mana Barrier. This gives increased survivability (from the armor, magic resistance, and synergy with Mana Barrier), decent amounts of attack damage, and helpful cooldown reduction.
Since Blitzcrank has trouble farming for gold, Aegis of the Legion can be used as a cheap and effective way to increase his survivability and usefulness to his team, especially if he's being built as a tanky-support role.

And some from me:
Be careful with ur Rocket Grab,maybe you will catch someone who kills you in 3 seconds,or maybe you catch a shroom,or jack in the box,or waste it on minion...
Spam E always like once in 10 seconds,it has 3/4 sec cd,so np
U need Mana for barrier and for damage and for not running out of mana?!?!!?
Use R always in teamfights...
While chasing someone that has more hp than your R active damage,try not using it,w8 for the lightning to get him with less than 500/400 hp,if we add the armor,mr...w8 til 300/200
