With this build I always get some kills.It is good because it got armor,magic resist and health.So we make him like a tank,but if we buy Frozen Mallet we give him some damage and we get some with runes and masteries.I usualy take fortify and heal but you can take something else.So in action try to use Courage and Courage give you up to 25 magic resist (you have to kill minions,so for each minion you kill he get 0.5 magic resist.When you get in the game first I usualy buy Null-Magic Mantle first because if my oposite champion is dealing magic damage,he deals less and I got chance to do first blood.
