Blitzcrank

Strengths

The 1-2-3 combo of Rocket Grab, Power Fist, and Static Field can devastate an individual opponent.
Using Blitzcrank's grab to pull an enemy into your tower range followed by a Power Fist will allow the tower to get several hits on them.

Passive · Mana Barrier — Blitzcrank gains a shield based on their mana when dropping to low health.
Q · Rocket Grab — Blitzcrank fires their right hand to grab an opponent on its path, dealing damage and dragging it back to them.
W · Overdrive — Blitzcrank super charges themself to get dramatically increased Move and Attack Speed. They are temporarily slowed after the effect ends.
E · Power Fist — Blitzcrank charges up their fist to make the next attack deal double damage and pop their target up in the air.
Ultimate · Static Field — Enemies attacked by Blitzcrank are marked and take lightning damage after 1 second. Additionally, Blitzcrank can activate this ability to remove nearby enemies' shields, damage them, and silence them briefly.

A suggested 5-lane lineup built around Blitzcrank, based on hero partnerships and role synergy — not win rate.
