My build for him was Warmog's Armor, Spirit Visage, Infinity Edge or Black Cleaver and an item that they got rid of that used to scale off max health, I can't remember it's name, Bloodthirster, and Guardian Angel. Game over. If I wanted a little faster build, I would get Sunfire Cape instead of Spirit Visage. If not Warmog, Trinity Force. Whoever feeds Garen to allow him to tank is just crazy.  ::)
