Gary Oak imo.
He would literally be 5 steps ahead of you.
* Just escaped a losing teamfight with barely any hp? Gary Oak is there to snipe you from across the map.
*Just escaped a gank with 5 hp and are recalling in a bush? Gary Oak is there to kill you right before the recall animation finishes.
* Just won a teamfight and are pushing the enemy Nexus? Game over, Gary Oak already BD'ed your nexus.
* Just opened your score screen to see if you're winning in CS with your measly 100? You're slow, Gary Oak had that 5 minutes ago and hes ganked 5 times.
