The Triple Rainbow. This involves 3 Summoners working together to bring ultimate destruction upon 1-5 champions. These champions are Ezreal, Lux, and Ashe. These three champions, with their combined abilities can turn a teamfight into a stunned, helpless, glowing ball of death.

With these three I like to start a team fight with and Ashe arrow then Lux and Ezreal correspond to do insane damage. It's actually quite hilarious watching everyone slowed try to Flash and Cleanse away but they cant escape... Make sure you have good teammates to allow for this beautiful combo.

Another suggestion I would give would be to have a tank like Galio(GGaliOP) or Amumu(Fearmahtears)- With their combined ults its even more AOE dmg and you can line up a perfect skillshot with Lux and Ez.

Ezreal- With Ezreal, I like to start off with a Doran's Ring for the HP and Mana Regen. My first back I get Ionian Boots of Lucidity for the CDR. During levels 6-11, always be watching other lanes. Pop CV on random patches when there's a MIA. You will usually find a Xin Zhao trying to gank you at mid. It
