This Kayle build is the best AP/AD carry. The fast attack speed, magic resist smashed, ability power, and Madreds Bloodrazor make you a great carry with a approx. 33% cool down on your ultimate your smashing up team fights. This is a aggressive build, with Madreds lowering their MR and hitting 4% of their their health per hit. Your W will also heal hard and the CD will be quick.

What I do to engage with a Sheen or Trinity force, I hit my E to trigger the CD and then Q the target. With this and the void staff you hit like a truck. (Hits even harder with Hextech off CD)
