Sounds like a MF/caitlyn Mash up = And wtf is with that smokescreen thing
I thinks these sound better (and it makes more sense) :
Quick draw (Passive) - Graves loves a good fight, and becomes more focused the more enemies there are around him. Increased attack speed per enemy champ nearby.
Buckshot - Fires ONE volley that deals moderate damage to all enemies in a (short) cone. Closer baddies take more damage than farther ones.
Lasso - Graves throws a lasso towards an enemy. If it hits a champion, it will Stun them and Graves can then drag them backwards (Like a reverse Bandage toss).
*Reserved for when I can think of a 3rd ability*
The Big Fifties (Ultimate) - Graves loads 2x .50 caliber rounds into his gun and fires both at target champ for massive damage and 1.5 second stun. Enemies around the target take xx% of the damage and are slowed for 1 second. (Has a short range)
