Accurate Rocket Grabs are Blitzcrank's core; their success is a key factor in determining lane victory.
The Q (Rocket Grab) to E (Power Fist) combo is incredibly fast, allowing you to instantly suppress enemies without giving them a chance to react.
If the enemy support is an AD champion, consider 'Death's Dance' as a first item to synergize with Aftershock.
