I heard some people say that Magnus the Magnataur is a ok strength hero. I see people rarely choose him or use him in some public games. His abilities are above-average, though. His shockwave has a pretty long range, his Empower is really good for increasing attack power. Also Mag's Mighty swing is a great combo with Battlefury dealing 85% cleave damage. His ultimate can take care of escaping heroes, if you have battlefury, say goodbye to your opponents. For my build: I use Boots of Travel, Sange & Yasha, Cranium Basher, Vanguard, Buriza-do Kyanon, and Assault Cuirass. I think that is one a good build for him. He would able to defeat and own most heroes. If I replace Sange & Yasha with a Heart of Tarrasque, he will have more hp and regeneration. So, I think this is a recommended build for him.
