Kill or Die build:
This build after lvl 20 is realy effective against more hero, you can kill a whole team at once, or die really quick. An Uther Divine Shield can be useful.
This hero have no selfheal, regen, or lifesteal at all so you need a healer, or you have go home really oftem.
Stay Safe build:
This speaks for it self. Becouse you dont have selfheal, regen, or lifesteal at all, this makes this hero much easier. Keep distance, and use worgen form for chasing, and finishing. After lvl 16 try to use Gilnean Cocktail when Inner Beast is active.
