The "I" in team Draven skin concept
The skin would consist of his axes being made of shining gold and fireworks when ever he got a kill. The fireworks would protrude quickly from the champion and explode 
in a non-game-play interfering way. He could have some dialogue that makes him more self centered. ie: "Im all a team needs..." He could wear a sport uniform and the number could be #1. Cool things like that to drive attention toward him.
