Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
so im putting this build up because i have had some good luck with it in 3v3, 5v5 games your meam throughout the entire duration of the game
for the runes build i went for a combination of atk speed,crit dmg, and ability cooldown. so you can decieve and two shiv poison as much as possible and keep the passive as much as you can
these masteries give you more ability cooldown along with monster buffs to harass in your lane and stay out lvling as much as possible
so these items are pretty set i dont get lvl 2 boots for a while just because trinity force makes up for the movement speed, but when i do upgrade them. when you get to the end of the build sell your doran's shield for a phantom dancer. this is an epensive build but unstoppable
in the begging of team fights i like to send in my illusion to hopefully get an enemy to use a few spells and if your lucky maybe get a WW to ulti on your illusion, then let your teammates go in first then you follow in right behind throwing down a Jib that little scare can always change the team fight in your favor, being able to dishout damage and easily chase down anyone else that is still alive.
since this build takes alot of gold around lvl 6 when you get your ulti is a good time to go eat up golem buffs everywhere jungling the map at the same time being able to provide suport and ganks to teammates
