Freeze your lane for the first 5 levels. A good trick is to let the opponent get into the lane and last hit 3 or 4 minions before you start last hitting. The lane will snowball in your direction and you can farm safely from your half of the lane.
I play Flat ap blues and quints, mana regen blues and spell pen reds. masteries are 9-21-0 for surviveability.
Early game I just last hit and drop my e on the enemy when ever I get a chance to slowly widdle them down. Once I hit 4 or 5 usually they are pretty low and I hit them with a full combo and most often take them down.
Items I build are RoA, BFT, Hat, Rylas, and then Abyssal. He needs a lot of durability to handle the bruiser meta in TT and the RoA and Rylas does the trick.
