Evelynn & My Luden's Build
You basically instakill anyone you can touch. Obviously, you're clean up crew in teamfights, but you can literally pick any member of the team off if they walk into a bush.

No boots and still maintain 421 base movement speed. (I use Sorc shoes until full build then switch out for shadows) 921 AP endgame (my mastery page doesn't include Archmage mastery).
Enjoy. I just lol'd as a murdered a tank Skarner instantly.
Notice me, Evelynn mains!

and I'm on board.
