Sit tight in lane until you get 2 level and your reactive armor. Pick up last hits when you can using whirling death to hit the creep and your opponent in lane. Use your mana productively, always leaving enough for a timber chain to save you or gank. When you are level 6 with arcanes you have the burst to gank, so rotate or have others rotate to you.

Now grab your cores quickly, and use your global presence to pressure their towers and improve your teams map control, whilst still geting to every fight.
