Absolutely blow people up from way far away. Combustion and Tainted Scepter give you ungodly amounts of burst. Prophecy and Typhoon give you just enough attack speed to get in and clean up if you need to. Play aggressively for poke in lane, play as safe as you can everywhere else.

Ability order: Q-E-RMB, Q max - E max - RMB max. Take ultimate when you can.
