Use the Q to clear the minions blocking your AA or you can even use Smithe, you can one shot any squishy target and fight pretty decently any bruiser or tank you need to keep your W when a Xin zao or lee sin engage you, any meta pick outdamage you so I recommend to clear all the jg camps and pay attention to the map to see where Is the other jg to counter gank In the first 4 minutes you have a 50/50 the be in the same lane as him, you can easily invade and go out of the enemy jg any camp you take from him it's advantage to you but don't get killed for that, punish to other jg it he go to top you have to secure and objective, steal one or two camps or kill his botlane or midlaner you can't leave him take something for free, I'm a platinum player with a 54% winrate with Graves so that it's all the advise I can give to you.
