Not Updated For Current Season
This is a build centered around getting an early gank and using a very cheap build to own late game.
The Item Build costs around 8270 gold total; this is very reasonable.
Your Main Combo:
Rocket Grab, (Optional*), Power Fist, Attack, (Optional**), Attack X times.
* Before Rocket Grab finishes, you can use Flash backwards to pull the enemy even farther away from their original location. This is very key to survivability in case the target has a laning partner.
Flash grab is now harder to pull off after the last patch affecting Blitzcrank.
** If you're too slow to catch your opponent at this part of the combo, use Overdrive if you have it. However, do not use it if you can't handle the slow down that proceeds (i.e. no tower diving after someone with this).
