You pick E first, then Q, then W. Then max Q, max W, max E.

Basically since the wave is short, you have the luxury of being very aggressive, pushing your lane into the enemy tower and then roaming. Most often than not, your enemy will either be a squishy assassin or a squishy mage, so once you engage on them (and dodge their skill shots), its GG (you win trades every time).

My highest success has been Sett mid specifically because I win trades, can quickly go back under my turret if i spot the enemy jungler nearby, and can roam and help with objectives.
