Threats to Blitzcrank with this build
About this build.
Win rate data was taken from http://lolalytics.com/champion/Blitzcrank/ on November 28, 2016.
Feel free to vary the build outside of the "core" recommended build. That is just what is generically ideal. Use the win rate data to inform your decisions on how to vary your build. For example, Banner of Command has the highest win rate because it is a great item when almost all of the enemy team's wave clear is AP. Try to consider the state of the game and the compositions of both teams for every item you build.
The only commonly built items that don't have a decent win rate on Blitz are the Spellthief's line of items and expensive boots (sorcs, mercs). Both heavy tank and heavy AP builds see a lot of success, as well as the generic tank/utility/CDR build.
If you want to save this page to an item set you can use in game, there is a Google Chrome extension called "LeagueSets" that can do that.
