Early game you will want to play passive, so as soon as you hit level 2, kill your lane opponent, so you can have an easy time farming creeps passively. Do not leave lane or the creeps may take your kill on the enemy top laner.

At this point you should still be farming creeps. Your team may ask you for help defending the Nexus Turrets, but you should laugh at them. You know better, fighting a 5v5 will only lead to disaster. Carry on freezing your lane.

Farm until you reach level 17. At this point, you will have enough money to buy your completed build, and go b for what should be the first time in the game if you have played it correctly. Buy your lucky picks and go get level 18.

Your ult now has no cooldown, so spam the button, and choose a target. Slowly stalk them like a sort of slenderman-tryndamere. Let them know their death is impending, then using your invincible self, hunt the enemy team down one by one, causing ragequits, trauma, and surrender. Make sure to bind your laugh to a nearby button, so the enemy team can hear the sound of your voice echoing around the map. Then, when you wish it, walk up to the enemy base and take it, with your invincibility. And don't worry if you forget to press r for a while. You have so many Lucky Picks that any attack has a 99% chance to leave you on 1 health, as you are the supreme lucker.
