Strategy:
My key for playing Ogre Magi is not by spell spamming since the spells have long cooldown, he has low mana to start with, and he only got one spell that deals most of the damage. So, SURVIVABILITY is my strategy at the early part of the game.

If you have another player fighting with you in a single lane, try working with him/her with respect to the item's you'll be getting and have some strategy fighting the opposing heroes so you'll have better chance of winning.

It will be better if you have another disabler, stunner or nuker fighting with you in a lane.

Try to control using your Fireblast and cast it first after you have your Multi Cast. This is why i needed those stats early on.

Tips: If you are eager to have a first kill, try spamming Fireblast, after getting Multi Cast, and hit him/her as much as you can and have some clarities or try getting at least a or so you'll have enough mana for another round. By then, if lucky enough, you'll double cast Fireblast and get the kill.
