This build is focused more on the Middle Lane. However, I did throw other useful items in if you wish to use this build in Top or Bottom lanes.

Suggestions:
1) Either start with the starting items I have chosen or go with a Bottle.
2) Farm up your Mana Boots ASAP (make sure you capture runes every 2 minutes).
3) Build your Refresher Orb.
4) Make sure you stay in the back of team fights and only cast your Ultimate when you think team fights are about to end.

Other than that, I hope you enjoy my build. :)
