Lethality Akali turn her Shuriken Flip into a death sentence, allowing her to one shot squish targets with just her E and her passive. Though due to the lack of Hextech Gunblade, this build is very risky as any hard CC will shut you down instantly and missing your E hurt your damage greatly. What you want to do in teamfights is land your E on squish target, dash towards them, and auto attack, then use your W to run away until your E is back up. Because the core items of this build max out your cooldown reduction, you should be able to pick off another target in a teamfight if you use your R to escape.
