This build is more for fun than for ranked or serious play - ap xin is simply not a strong competitive pick - but if you want to be able to 1v1 turrets, and pretty much anyone in the game late, then you should try this build. Play this build if you you have an easy ad snowball top like riven, rengar, or zed. Shen or other tank can also work - also it is best played against an enemy jg that is weak early like ammumu or yi.
