Has anyone tried AD or Hybrid Kat ? If so, how is it ?

I wanted to try new builds just to fool around, and thought of doing hybrid Kat.

I came up with Hextech Gunblade, Death's dance, Luden's, Rabbadons and Infinity edge with Boots of swiftness. I got gunblade and deaths dance for the spell vamp, and the rest I just bought whatever gave the most AD and AP. The biggest problem I noticed with this is that build that you need to add in auto's to deal decent damage.

Anyone that has any builds that actually work ?
