Why Aftershock

As Blitz you can easily proc Aftershock to continue fighting. The explosion further assist in kill potential.

Why Demolish

Demolish on Blitzcrank is great for snowballing early lane picks/kills into meaningful tower damage and early gold advantage.

Why Second Wind

Second Wind's mid-fight health sustain is great for level 2 all-ins and lane trades where the extra health can be the difference between death or a double kill.

Why Unflinching

Unflinching on Blitz allows you to stick to your target after hooking them so you can follow up provide extra CC and damage.

WhyBiscuit Delivery

Biscuit Delivery paired with Second Wind and Bone Plating make you a resilient tank in skirmishes as well as allow you to shrug off any incoming poke damage.

WhyCosmic Insight

More CDR from Cosmic Insight means more chances for hooks and teamfight CC with [E].
