q first, e seems sluggish early game. I can't seem to use E properly without slowing them with q first. maybe its cuz i only played against like ahri, leblanc, and azir.
but I've been rushing zhonyas, for the trick ult plays. then ludens echo, because its like... made for him...
sometimes vise-versa
lichbane is a VERY good item on him, procs with his E anyways.
top it off with void or rabadons
