If you're playing urf: Try AP nunu

Its legit the most fun i had in ever on urf. What i did was rush luden every game and then get every 100+ ap item, and void staff. Sorc shoes w alacrity.

(E>Q>W) - do a camp at lv 1 and tp top. Start snowball anyway since you dont spike lvl 2 right away.

Why it works so well now is that they reduced Nunu's E cd a while ago.

Here's a video of it in action by the way.
