Play like you normally would at the start, play passively later and defend lanes, go jungle on the enemy side if you feel like it
Spam your ult across the map to annoy your enemies lol
TIP: look at the top of your screen, if you see an enemy with low health DROP A NUKE ON THEM ASAP
Although this build is for distraction if you get a few stacks on your ult you will dominate.
