Ogre Magi is a really fun support hero to play as because his abilities are mostly disables! I recommend playing Ogre Magi in either side lane (Top or bottom) with another hero that has a disable for easy kills. He is very scary in a trilane and has fantastic strength gain as an intelligence hero. (How ironic...) This build revolves around maxing Fireblast and Ignite for maximum damage potential and that you get farm when the match is slow. Give it a try and let me know how the guide works out for you!
