Blitzcrank (Blitz as I will call him from here on) is a tanky Dps top laner capable of locking down and disrupting enemy teams as well as initiating fights. Blitz is very powerful at receiving ganks as well as bullying enemies with low sustain out of lane. Blitz has a rough start, but once he gets into the swing of things he is capable of easily cleaning up the enemy team and winning games for his team. Blitz top also brings a pull to the table for endgame allowing even games that should be lost to be won with just a good pull.

Mana Barrier- When Blitzcrank's life is brought below 20% health, he creates a Mana Barrier, a shield with 50% of his current mana, which lasts 10 seconds. The activation doesn't consume any mana. This effect has a one minute cooldown.
This passive is so strong. Its like a heal bait in a passive. Late game when you have alot of mana this skill will act like another hp bar for you. The one thing to note is that this skill goes off CURRENT MANA. If you are low on hp and low on mana do not be expecting a reliable bait from your passive.

Rocket Grab- Blitzcrank fires his right hand at a straight line to the target area. If his hand encounters an enemy unit it will stun them, deal 80 / 135 / 190 / 245 / 300 (+100% of ability power) magic damage, and pull the enemy unit to him.
This skill is INSANE. This is one of THE BIGGEST game changing moves in the ENTIRE game. This skill allows you to initiate a fight by pulling a squishy in you team, pull back a fleeing enemy after they flash or ghost, or just lock down an enemy with CC. In lane you should make attempts to pull your opponent under tower to get a bunch of free harass (and if played well enough) probably a kill.

Overdrive- Blitzcrank super charges himself to increase Movement Speed by 16 / 20 / 24 / 28 / 32 % and attack speed by 30 / 38 / 46 / 54 / 62 % for 8 seconds.
This skill is your main mobility skill, the use of this for you will mostly be to gain ground so you can fire off a good hook with your Q, however the AS is nice when you have some AD or when you are trying to last hit under tower in your lane.

Power Fist- Blitzcrank charges up his fist to make his next attack deal double his total attack damage and pop his target up in the air.
This attack is basically a sheen hit on your next basic attacks with a knockup added on for good measure. Once you get your sheen this skill will be doing TONS OF DAMAGE. This skill is a very good followup to your Q to lock enemies in place and allow your team/jungler more attacking time.
Note: This skill can be used on towers, allowing blitz to push very well.

Static Field- Passive: Lightning arcs off of Blitzcrank to hit a random nearby enemy for 100 / 200 / 300 (+25% of ability power) magic damage every 2.5 seconds (not affected by cooldown reduction). This will not damage enemies in stealth.mActive: Deals 250 / 375 / 500 (+100% of ability power) magic damage and silences surrounding enemy units for 0.5 seconds. The passive is not in effect during the cooldown.
This skill is the greatest love and hate of blitz top lane, You will love this skill as it allows you to push the lane at will, provides good CC, AND does a VERY good amount of damage to enemies with the active. All while having a very low 30 second cooldown. This skill is dislikable due to the fact the passive will push your lane without you wanting it to AND hit the minions to screw up your CSing on tower.

• Use your ultimate before walking in the baron pit if you have an oracles or a vision to clear a ward, as the lightning will pull them on you.
• Play passive until 6 as that is when you gain most of your burst damage.
• If possible try and use your knockup followed by your Q as it is a safer way to be guaranteeing the pull damage.
• Invade the enemies jungle and pull the buff you think they are starting at over the wall to hurt their jungle time.

• Do not stand near walls and let blitz pull you.
• Do not underestimate a low hp blitz, you may find yourself dead on the ground while hes laughing with a mana shield on.
• Use your ultimate to harass the enemy whenever possible as it will prevent your passive from making you miss CS as well as dealing decent damage and letting the cooldown start ticking again.

Nomad's Medallion, Heart of Gold, and kage's Lucky Pick - Keeps your gold amount healthy as well as giving you useful stats. Also upgrading them makes them useful items.

Abyssal Mask- Makes enemies weaker to your ultimate as well as your AP carry.

Will of the Ancients- Well if you want to run a double Wota comp.

Banshee's Veil- Makes you strong against CC and vs mages.

Blitz is strong in soloQ as 1 good pull can win the game.

Blitz is a strong pick in ranked 5s as enemies will not expect him top, and you can coordinate invades and such so much better.

Pros:

-Amazing CC
-Good pull
-High burst
-Low cooldown ult.
-Safe

Cons:

-Ultimate has negatives
-High mana costs
-Weak early on.

This is my top facts blitzcrank. Blitz is an amazingly underrated top lane pick that takes patience and dedication to master. His grab can hard carry a game especially if he has the damaging power to back his CC up. As always summoners i hope you have a good day and good luck on the fields of Justice!

SERIES UPDATE: Guide release will be soon. =D
