Here's a version of Mirage that focuses on Spirit damage earl-mid game, and later transitions to Bullet a bit more. Early on you will focus on poking the enemy and farming, looking for kill potential in lane but not overextending. When you get around Kinetic Dash, look to roam and wreak havoc around the map. Your ganking abilities are great, you can burst down anyone with a single other teammate, Mid and late game you will transition more into gun damage, picking up even more utility and ganking abilities on the way. Go in, get the kills, get out. You will play back a little more than usual, making sure you set the debuffs on people.
